firesat: copyrights, rename to firedtv, API conversions, fix remote control input Combination of the following changes: Tue, 26 Aug 2008 00:17:30 +0200 (CEST) firedtv: fix remote control input and update the scancode-to-keycode mapping to a current model. Per default, various media key keycodes are emitted which closely match what is printed on the remote. Userland can modify the mapping by means of evdev ioctls. (Not tested.) The old scancode-to-keycode mapping is left in the driver but cannot be modified by ioctls. This preserves status quo for old remotes. Tue, 26 Aug 2008 00:11:28 +0200 (CEST) firedtv: replace tasklet by workqueue job Non-atomic context is a lot nicer to work with. Sun, 24 Aug 2008 23:30:00 +0200 (CEST) firedtv: move some code back to ieee1394 core Partially reverts "ieee1394: remove unused code" of Linux 2.6.25. Sun, 24 Aug 2008 23:29:30 +0200 (CEST) firedtv: replace semaphore by mutex firesat->avc_sem and ->demux_sem have been used exactly like a mutex. The only exception is the schedule_remotecontrol tasklet which did a down_trylock in atomic context. This is not possible with mutex_trylock; however the whole remote control related code is non-functional anyway at the moment. This should be fixed eventually, probably by turning the tasklet into a worqueue job. Convert everything else from semaphore to mutex. Also rewrite a few of the affected functions to unlock the mutex at a single exit point, instead of in several branches. Sun, 24 Aug 2008 23:28:45 +0200 (CEST) firedtv: some header cleanups Unify #ifndef/#define/#endif guards against multiple inclusion. Drop extern keyword from function declarations. Remove #include's into header files where struct declarations suffice. Remove unused ohci1394 interface and related unused ieee1394 interfaces. Add a few missing #include's and remove a few apparently obsolete ones. Sort them alphabetically. Sun, 24 Aug 2008 23:27:45 +0200 (CEST) firedtv: nicer registration message and some initialization fixes Print the correct name in dvb_register_adapter(). While we are at it, replace two switch cascades by one for loop, remove a superfluous member of struct firesat and of two unused arguments of AVCIdentifySubunit(), and fix bogus kfree's in firesat_dvbdev_init(). Tue, 26 Aug 2008 14:24:17 +0200 (CEST) firesat: rename to firedtv Suggested by Andreas Monitzer. Besides DVB-S/-S2 receivers, the driver also supports DVB-C and DVB-T receivers, hence the previous project name is too narrow now. Not yet done: Rename source directory, files, types, variables...

#include <linux/kernel.h>
include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

#include <linux/slab.h>
firedtv: cleanups and minor fixes Combination of the following changes: Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: increase FCP frame length for DVB-S2 tune QSPK The last three bytes didn't go out to the wire. Effect of the fix not yet tested. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: replace mdelay by msleep These functions can sleep (and in fact sleep for the duration of a whole FCP transaction). Hence msleep is more appropriate here. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: trivial reorganization in avc_api Reduce nesting level by factoring code out of avc_tuner_dsd() into helper functions. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: trivial cleanups in avc_api Use dev_err(), no CamelCase function names, adjust comment style, put #if 0 around unused code and add FIXME comments, standardize on lower-case hexadecimal constants, use ALIGN() for some frame length calculations, make a local function static... The code which writes FCP command frames and reads FCP response frames is not yet brought into canonical kernel coding style because this involves changes of typedefs (on-the-wire bitfields). Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: don't retry oPCR updates endlessly In the theoretical case that the target node wasn't handling the lock transactions as expected or there was continued interference by other initiating nodes, these functions wouldn't return for ages. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: remove bitfield typedefs from cmp, fix for big endian CPUs Use macros/ inline functions/ standard byte order accessors to read and write oPCR register values (big endian bitfields, on-the-wire data). The new code may not be the ultimate optimum, but it doesn't occur in a hot path. This fixes the CMP code for big endian CPUs. So far I tested it only on a little endian CPU though. For now, include <asm/byteorder.h> instead of <linux/byteorder.h> because drivers/ieee1394/*.h also include the former. I will fix this in drivers/ieee1394 and firedtv later. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: trivial cleanups in cmp Reduce nesting level by means of early exit and goto. Remove obsolete includes, use dev_err(), no CamelCase function names... Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: trivial cleanups in firesat-ci Whitespace, variable names, comment style... Also, use dvb_generic_open() and dvb_generic_release() directly as our hooks in struct file_operations because firedtv's wrappers merely called these generic functions. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: remove CA debug code This looks like it is not necessary to have available for endusers who cannot patch kernels for bug reporting and tests of fixes. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: remove AV/C debug code This looks like it is not necessary to have available for endusers who cannot patch kernels for bug reporting and tests of fixes. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: remove various debug code Most of this was already commented out. And that which wasn't is not relevant in normal use. Mon, 29 Sep 2008 19:22:48 +0200 (CEST) firedtv: register input device as child of a FireWire device Instead of one virtual input device which exists for the whole lifetime of the driver and receives events from all connected FireDTVs, register one input device for each firedtv device. These input devices will show up as children of the respective firedtv devices in the sysfs hierarchy. However, the implementation falls short because of a bug in userspace: Udev's path_id script gets stuck with 100% CPU utilization, maybe because of an assumption about the maximum ieee1394 device hierarchy depth. To avoid this bug, we use the fw-host device instead of the proper unit_directory device as parent of the input device. There is hope that the port to the new firewire stack won't be inhibited by this userspace bug because there are no fw-host devices there. Mon, 29 Sep 2008 19:21:52 +0200 (CEST) firedtv: fix string comparison and a few sparse warnings Sparse found a bug: while ((kv_buf + kv_len - 1) == '\0') should have been while (kv_buf[kv_len - 1] == '\0') We fix it by a better implementation without a temporary copy. Also fix sparse warnings of 0 instead of NULL and signedness mismatches. Mon, 29 Sep 2008 19:21:20 +0200 (CEST) firedtv: remove unused struct members and redefine an int as a bool. Mon, 29 Sep 2008 19:20:36 +0200 (CEST) firedtv: fix initialization of dvb_frontend.ops There was a NULL pointer reference if no dvb_frontend_info was found. Also, don't directly assign struct typed values to struct typed variables. Instead write out assignments to individual strcut members. This reduces module size by about 1 kB. Mon, 29 Sep 2008 19:19:41 +0200 (CEST) firedtv: remove unused dual subunit code from initialization No FireDTVs with more than one subunit exists, hence simplify the initialization for the special case of one subunit. The driver was able to check for more than one subunit but was broken for more than two subunits. While we are at it, add several missing cleanups after failure, and include a few dynamically allocated structures diretly into struct firesat instead of allocating them separately. Mon, 29 Sep 2008 19:19:08 +0200 (CEST) firedtv: add vendor_id and version to driver match table Now that nodemgr was enhanced to match against the root directory's vendor ID if there isn't one in the unit directory, use this to prevent firedtv to be bound to wrong devices by accident. Also add the AV/C software version ID to the match flags for completeness; specifier ID and software only make sense as a pair. Mon, 29 Sep 2008 19:18:30 +0200 (CEST) firedtv: use hpsb_node_read(), _write(), _lock() because they are simpler and treat the node generation more correctly. While we are at it, clean up and simplify surrounding code. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

firedtv: cleanups and minor fixes Combination of the following changes: Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: increase FCP frame length for DVB-S2 tune QSPK The last three bytes didn't go out to the wire. Effect of the fix not yet tested. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: replace mdelay by msleep These functions can sleep (and in fact sleep for the duration of a whole FCP transaction). Hence msleep is more appropriate here. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: trivial reorganization in avc_api Reduce nesting level by factoring code out of avc_tuner_dsd() into helper functions. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: trivial cleanups in avc_api Use dev_err(), no CamelCase function names, adjust comment style, put #if 0 around unused code and add FIXME comments, standardize on lower-case hexadecimal constants, use ALIGN() for some frame length calculations, make a local function static... The code which writes FCP command frames and reads FCP response frames is not yet brought into canonical kernel coding style because this involves changes of typedefs (on-the-wire bitfields). Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: don't retry oPCR updates endlessly In the theoretical case that the target node wasn't handling the lock transactions as expected or there was continued interference by other initiating nodes, these functions wouldn't return for ages. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: remove bitfield typedefs from cmp, fix for big endian CPUs Use macros/ inline functions/ standard byte order accessors to read and write oPCR register values (big endian bitfields, on-the-wire data). The new code may not be the ultimate optimum, but it doesn't occur in a hot path. This fixes the CMP code for big endian CPUs. So far I tested it only on a little endian CPU though. For now, include <asm/byteorder.h> instead of <linux/byteorder.h> because drivers/ieee1394/*.h also include the former. I will fix this in drivers/ieee1394 and firedtv later. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: trivial cleanups in cmp Reduce nesting level by means of early exit and goto. Remove obsolete includes, use dev_err(), no CamelCase function names... Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: trivial cleanups in firesat-ci Whitespace, variable names, comment style... Also, use dvb_generic_open() and dvb_generic_release() directly as our hooks in struct file_operations because firedtv's wrappers merely called these generic functions. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: remove CA debug code This looks like it is not necessary to have available for endusers who cannot patch kernels for bug reporting and tests of fixes. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: remove AV/C debug code This looks like it is not necessary to have available for endusers who cannot patch kernels for bug reporting and tests of fixes. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: remove various debug code Most of this was already commented out. And that which wasn't is not relevant in normal use. Mon, 29 Sep 2008 19:22:48 +0200 (CEST) firedtv: register input device as child of a FireWire device Instead of one virtual input device which exists for the whole lifetime of the driver and receives events from all connected FireDTVs, register one input device for each firedtv device. These input devices will show up as children of the respective firedtv devices in the sysfs hierarchy. However, the implementation falls short because of a bug in userspace: Udev's path_id script gets stuck with 100% CPU utilization, maybe because of an assumption about the maximum ieee1394 device hierarchy depth. To avoid this bug, we use the fw-host device instead of the proper unit_directory device as parent of the input device. There is hope that the port to the new firewire stack won't be inhibited by this userspace bug because there are no fw-host devices there. Mon, 29 Sep 2008 19:21:52 +0200 (CEST) firedtv: fix string comparison and a few sparse warnings Sparse found a bug: while ((kv_buf + kv_len - 1) == '\0') should have been while (kv_buf[kv_len - 1] == '\0') We fix it by a better implementation without a temporary copy. Also fix sparse warnings of 0 instead of NULL and signedness mismatches. Mon, 29 Sep 2008 19:21:20 +0200 (CEST) firedtv: remove unused struct members and redefine an int as a bool. Mon, 29 Sep 2008 19:20:36 +0200 (CEST) firedtv: fix initialization of dvb_frontend.ops There was a NULL pointer reference if no dvb_frontend_info was found. Also, don't directly assign struct typed values to struct typed variables. Instead write out assignments to individual strcut members. This reduces module size by about 1 kB. Mon, 29 Sep 2008 19:19:41 +0200 (CEST) firedtv: remove unused dual subunit code from initialization No FireDTVs with more than one subunit exists, hence simplify the initialization for the special case of one subunit. The driver was able to check for more than one subunit but was broken for more than two subunits. While we are at it, add several missing cleanups after failure, and include a few dynamically allocated structures diretly into struct firesat instead of allocating them separately. Mon, 29 Sep 2008 19:19:08 +0200 (CEST) firedtv: add vendor_id and version to driver match table Now that nodemgr was enhanced to match against the root directory's vendor ID if there isn't one in the unit directory, use this to prevent firedtv to be bound to wrong devices by accident. Also add the AV/C software version ID to the match flags for completeness; specifier ID and software only make sense as a pair. Mon, 29 Sep 2008 19:18:30 +0200 (CEST) firedtv: use hpsb_node_read(), _write(), _lock() because they are simpler and treat the node generation more correctly. While we are at it, clean up and simplify surrounding code. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

Effect of the fix not yet tested. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: replace mdelay by msleep These functions can sleep (and in fact sleep for the duration of a whole FCP transaction). Hence msleep is more appropriate here. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: trivial reorganization in avc_api Reduce nesting level by factoring code out of avc_tuner_dsd() into helper functions. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: trivial cleanups in avc_api Use dev_err(), no CamelCase function names, adjust comment style, put #if 0 around unused code and add FIXME comments, standardize on lower-case hexadecimal constants, use ALIGN() for some frame length calculations, make a local function static... The code which writes FCP command frames and reads FCP response frames is not yet brought into canonical kernel coding style because this involves changes of typedefs (on-the-wire bitfields). Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: don't retry oPCR updates endlessly In the theoretical case that the target node wasn't handling the lock transactions as expected or there was continued interference by other initiating nodes, these functions wouldn't return for ages. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: remove bitfield typedefs from cmp, fix for big endian CPUs Use macros/ inline functions/ standard byte order accessors to read and write oPCR register values (big endian bitfields, on-the-wire data). The new code may not be the ultimate optimum, but it doesn't occur in a hot path. This fixes the CMP code for big endian CPUs. So far I tested it only on a little endian CPU though. For now, include <asm/byteorder.h> instead of <linux/byteorder.h> because drivers/ieee1394/*.h also include the former. I will fix this in drivers/ieee1394 and firedtv later. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: trivial cleanups in cmp Reduce nesting level by means of early exit and goto. Remove obsolete includes, use dev_err(), no CamelCase function names... Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: trivial cleanups in firesat-ci Whitespace, variable names, comment style... Also, use dvb_generic_open() and dvb_generic_release() directly as our hooks in struct file_operations because firedtv's wrappers merely called these generic functions. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: remove CA debug code This looks like it is not necessary to have available for endusers who cannot patch kernels for bug reporting and tests of fixes. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: remove AV/C debug code This looks like it is not necessary to have available for endusers who cannot patch kernels for bug reporting and tests of fixes. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: remove various debug code Most of this was already commented out. And that which wasn't is not relevant in normal use. Mon, 29 Sep 2008 19:22:48 +0200 (CEST) firedtv: register input device as child of a FireWire device Instead of one virtual input device which exists for the whole lifetime of the driver and receives events from all connected FireDTVs, register one input device for each firedtv device. These input devices will show up as children of the respective firedtv devices in the sysfs hierarchy. However, the implementation falls short because of a bug in userspace: Udev's path_id script gets stuck with 100% CPU utilization, maybe because of an assumption about the maximum ieee1394 device hierarchy depth. To avoid this bug, we use the fw-host device instead of the proper unit_directory device as parent of the input device. There is hope that the port to the new firewire stack won't be inhibited by this userspace bug because there are no fw-host devices there. Mon, 29 Sep 2008 19:21:52 +0200 (CEST) firedtv: fix string comparison and a few sparse warnings Sparse found a bug: while ((kv_buf + kv_len - 1) == '\0') should have been while (kv_buf[kv_len - 1] == '\0') We fix it by a better implementation without a temporary copy. Also fix sparse warnings of 0 instead of NULL and signedness mismatches. Mon, 29 Sep 2008 19:21:20 +0200 (CEST) firedtv: remove unused struct members and redefine an int as a bool. Mon, 29 Sep 2008 19:20:36 +0200 (CEST) firedtv: fix initialization of dvb_frontend.ops There was a NULL pointer reference if no dvb_frontend_info was found. Also, don't directly assign struct typed values to struct typed variables. Instead write out assignments to individual strcut members. This reduces module size by about 1 kB. Mon, 29 Sep 2008 19:19:41 +0200 (CEST) firedtv: remove unused dual subunit code from initialization No FireDTVs with more than one subunit exists, hence simplify the initialization for the special case of one subunit. The driver was able to check for more than one subunit but was broken for more than two subunits. While we are at it, add several missing cleanups after failure, and include a few dynamically allocated structures diretly into struct firesat instead of allocating them separately. Mon, 29 Sep 2008 19:19:08 +0200 (CEST) firedtv: add vendor_id and version to driver match table Now that nodemgr was enhanced to match against the root directory's vendor ID if there isn't one in the unit directory, use this to prevent firedtv to be bound to wrong devices by accident. Also add the AV/C software version ID to the match flags for completeness; specifier ID and software only make sense as a pair. Mon, 29 Sep 2008 19:18:30 +0200 (CEST) firedtv: use hpsb_node_read(), _write(), _lock() because they are simpler and treat the node generation more correctly. While we are at it, clean up and simplify surrounding code. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

firesat: copyrights, rename to firedtv, API conversions, fix remote control input Combination of the following changes: Tue, 26 Aug 2008 00:17:30 +0200 (CEST) firedtv: fix remote control input and update the scancode-to-keycode mapping to a current model. Per default, various media key keycodes are emitted which closely match what is printed on the remote. Userland can modify the mapping by means of evdev ioctls. (Not tested.) The old scancode-to-keycode mapping is left in the driver but cannot be modified by ioctls. This preserves status quo for old remotes. Tue, 26 Aug 2008 00:11:28 +0200 (CEST) firedtv: replace tasklet by workqueue job Non-atomic context is a lot nicer to work with. Sun, 24 Aug 2008 23:30:00 +0200 (CEST) firedtv: move some code back to ieee1394 core Partially reverts "ieee1394: remove unused code" of Linux 2.6.25. Sun, 24 Aug 2008 23:29:30 +0200 (CEST) firedtv: replace semaphore by mutex firesat->avc_sem and ->demux_sem have been used exactly like a mutex. The only exception is the schedule_remotecontrol tasklet which did a down_trylock in atomic context. This is not possible with mutex_trylock; however the whole remote control related code is non-functional anyway at the moment. This should be fixed eventually, probably by turning the tasklet into a worqueue job. Convert everything else from semaphore to mutex. Also rewrite a few of the affected functions to unlock the mutex at a single exit point, instead of in several branches. Sun, 24 Aug 2008 23:28:45 +0200 (CEST) firedtv: some header cleanups Unify #ifndef/#define/#endif guards against multiple inclusion. Drop extern keyword from function declarations. Remove #include's into header files where struct declarations suffice. Remove unused ohci1394 interface and related unused ieee1394 interfaces. Add a few missing #include's and remove a few apparently obsolete ones. Sort them alphabetically. Sun, 24 Aug 2008 23:27:45 +0200 (CEST) firedtv: nicer registration message and some initialization fixes Print the correct name in dvb_register_adapter(). While we are at it, replace two switch cascades by one for loop, remove a superfluous member of struct firesat and of two unused arguments of AVCIdentifySubunit(), and fix bogus kfree's in firesat_dvbdev_init(). Tue, 26 Aug 2008 14:24:17 +0200 (CEST) firesat: rename to firedtv Suggested by Andreas Monitzer. Besides DVB-S/-S2 receivers, the driver also supports DVB-C and DVB-T receivers, hence the previous project name is too narrow now. Not yet done: Rename source directory, files, types, variables...

However, the implementation falls short because of a bug in userspace: Udev's path_id script gets stuck with 100% CPU utilization, maybe because of an assumption about the maximum ieee1394 device hierarchy depth. To avoid this bug, we use the fw-host device instead of the proper unit_directory device as parent of the input device. There is hope that the port to the new firewire stack won't be inhibited by this userspace bug because there are no fw-host devices there. Mon, 29 Sep 2008 19:21:52 +0200 (CEST) firedtv: fix string comparison and a few sparse warnings Sparse found a bug: while ((kv_buf + kv_len - 1) == '\0') should have been while (kv_buf[kv_len - 1] == '\0') We fix it by a better implementation without a temporary copy. Also fix sparse warnings of 0 instead of NULL and signedness mismatches. Mon, 29 Sep 2008 19:21:20 +0200 (CEST) firedtv: remove unused struct members and redefine an int as a bool. Mon, 29 Sep 2008 19:20:36 +0200 (CEST) firedtv: fix initialization of dvb_frontend.ops There was a NULL pointer reference if no dvb_frontend_info was found. Also, don't directly assign struct typed values to struct typed variables. Instead write out assignments to individual strcut members. This reduces module size by about 1 kB. Mon, 29 Sep 2008 19:19:41 +0200 (CEST) firedtv: remove unused dual subunit code from initialization No FireDTVs with more than one subunit exists, hence simplify the initialization for the special case of one subunit. The driver was able to check for more than one subunit but was broken for more than two subunits. While we are at it, add several missing cleanups after failure, and include a few dynamically allocated structures diretly into struct firesat instead of allocating them separately.

Also add the AV/C software version ID to the match flags for completeness; specifier ID and software only make sense as a pair.

firedtv: cleanups and minor fixes Combination of the following changes: Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: increase FCP frame length for DVB-S2 tune QSPK The last three bytes didn't go out to the wire. Effect of the fix not yet tested. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: replace mdelay by msleep These functions can sleep (and in fact sleep for the duration of a whole FCP transaction). Hence msleep is more appropriate here. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: trivial reorganization in avc_api Reduce nesting level by factoring code out of avc_tuner_dsd() into helper functions. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: trivial cleanups in avc_api Use dev_err(), no CamelCase function names, adjust comment style, put #if 0 around unused code and add FIXME comments, standardize on lower-case hexadecimal constants, use ALIGN() for some frame length calculations, make a local function static... The code which writes FCP command frames and reads FCP response frames is not yet brought into canonical kernel coding style because this involves changes of typedefs (on-the-wire bitfields). Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: don't retry oPCR updates endlessly In the theoretical case that the target node wasn't handling the lock transactions as expected or there was continued interference by other initiating nodes, these functions wouldn't return for ages. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: remove bitfield typedefs from cmp, fix for big endian CPUs Use macros/ inline functions/ standard byte order accessors to read and write oPCR register values (big endian bitfields, on-the-wire data). The new code may not be the ultimate optimum, but it doesn't occur in a hot path. This fixes the CMP code for big endian CPUs. So far I tested it only on a little endian CPU though. For now, include <asm/byteorder.h> instead of <linux/byteorder.h> because drivers/ieee1394/*.h also include the former. I will fix this in drivers/ieee1394 and firedtv later. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: trivial cleanups in cmp Reduce nesting level by means of early exit and goto. Remove obsolete includes, use dev_err(), no CamelCase function names... Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: trivial cleanups in firesat-ci Whitespace, variable names, comment style... Also, use dvb_generic_open() and dvb_generic_release() directly as our hooks in struct file_operations because firedtv's wrappers merely called these generic functions.

firesat: copyrights, rename to firedtv, API conversions, fix remote control input Combination of the following changes: Tue, 26 Aug 2008 00:17:30 +0200 (CEST) firedtv: fix remote control input and update the scancode-to-keycode mapping to a current model. Per default, various media key keycodes are emitted which closely match what is printed on the remote. Userland can modify the mapping by means of evdev ioctls. (Not tested.) The old scancode-to-keycode mapping is left in the driver but cannot be modified by ioctls. This preserves status quo for old remotes. Tue, 26 Aug 2008 00:11:28 +0200 (CEST) firedtv: replace tasklet by workqueue job Non-atomic context is a lot nicer to work with. Sun, 24 Aug 2008 23:30:00 +0200 (CEST) firedtv: move some code back to ieee1394 core Partially reverts "ieee1394: remove unused code" of Linux 2.6.25. Sun, 24 Aug 2008 23:29:30 +0200 (CEST) firedtv: replace semaphore by mutex firesat->avc_sem and ->demux_sem have been used exactly like a mutex. The only exception is the schedule_remotecontrol tasklet which did a down_trylock in atomic context. This is not possible with mutex_trylock; however the whole remote control related code is non-functional anyway at the moment. This should be fixed eventually, probably by turning the tasklet into a worqueue job. Convert everything else from semaphore to mutex. Also rewrite a few of the affected functions to unlock the mutex at a single exit point, instead of in several branches. Sun, 24 Aug 2008 23:28:45 +0200 (CEST) firedtv: some header cleanups Unify #ifndef/#define/#endif guards against multiple inclusion. Drop extern keyword from function declarations. Remove #include's into header files where struct declarations suffice. Remove unused ohci1394 interface and related unused ieee1394 interfaces. Add a few missing #include's and remove a few apparently obsolete ones. Sort them alphabetically.

The old scancode-to-keycode mapping is left in the driver but cannot be modified by ioctls. This preserves status quo for old remotes. Tue, 26 Aug 2008 00:11:28 +0200 (CEST) firedtv: replace tasklet by workqueue job Non-atomic context is a lot nicer to work with. Sun, 24 Aug 2008 23:30:00 +0200 (CEST) firedtv: move some code back to ieee1394 core Partially reverts "ieee1394: remove unused code" of Linux 2.6.25. Sun, 24 Aug 2008 23:29:30 +0200 (CEST) firedtv: replace semaphore by mutex firesat->avc_sem and ->demux_sem have been used exactly like a mutex. The only exception is the schedule_remotecontrol tasklet which did a down_trylock in atomic context. This is not possible with mutex_trylock; however the whole remote control related code is non-functional anyway at the moment. This should be fixed eventually, probably by turning the tasklet into a worqueue job. Convert everything else from semaphore to mutex. Also rewrite a few of the affected functions to unlock the mutex at a single exit point, instead of in several branches. Sun, 24 Aug 2008 23:28:45 +0200 (CEST) firedtv: some header cleanups Unify #ifndef/#define/#endif guards against multiple inclusion. Drop extern keyword from function declarations. Remove #include's into header files where struct declarations suffice. Remove unused ohci1394 interface and related unused ieee1394 interfaces. Add a few missing #include's and remove a few apparently obsolete ones. Sort them alphabetically. Sun, 24 Aug 2008 23:27:45 +0200 (CEST) firedtv: nicer registration message and some initialization fixes Print the correct name in dvb_register_adapter(). While we are at it, replace two switch cascades by one for loop, remove a superfluous member of struct firesat and of two unused arguments of AVCIdentifySubunit(), and fix bogus kfree's in firesat_dvbdev_init(). Tue, 26 Aug 2008 14:24:17 +0200 (CEST) firesat: rename to firedtv Suggested by Andreas Monitzer. Besides DVB-S/-S2 receivers, the driver also supports DVB-C and DVB-T receivers, hence the previous project name is too narrow now. Not yet done: Rename source directory, files, types, variables...

firedtv: cleanups and minor fixes Combination of the following changes: Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: increase FCP frame length for DVB-S2 tune QSPK The last three bytes didn't go out to the wire. Effect of the fix not yet tested. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: replace mdelay by msleep These functions can sleep (and in fact sleep for the duration of a whole FCP transaction). Hence msleep is more appropriate here. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: trivial reorganization in avc_api Reduce nesting level by factoring code out of avc_tuner_dsd() into helper functions. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: trivial cleanups in avc_api Use dev_err(), no CamelCase function names, adjust comment style, put #if 0 around unused code and add FIXME comments, standardize on lower-case hexadecimal constants, use ALIGN() for some frame length calculations, make a local function static... The code which writes FCP command frames and reads FCP response frames is not yet brought into canonical kernel coding style because this involves changes of typedefs (on-the-wire bitfields). Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: don't retry oPCR updates endlessly In the theoretical case that the target node wasn't handling the lock transactions as expected or there was continued interference by other initiating nodes, these functions wouldn't return for ages. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: remove bitfield typedefs from cmp, fix for big endian CPUs Use macros/ inline functions/ standard byte order accessors to read and write oPCR register values (big endian bitfields, on-the-wire data). The new code may not be the ultimate optimum, but it doesn't occur in a hot path. This fixes the CMP code for big endian CPUs. So far I tested it only on a little endian CPU though. For now, include <asm/byteorder.h> instead of <linux/byteorder.h> because drivers/ieee1394/*.h also include the former. I will fix this in drivers/ieee1394 and firedtv later. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: trivial cleanups in cmp Reduce nesting level by means of early exit and goto. Remove obsolete includes, use dev_err(), no CamelCase function names... Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: trivial cleanups in firesat-ci Whitespace, variable names, comment style... Also, use dvb_generic_open() and dvb_generic_release() directly as our hooks in struct file_operations because firedtv's wrappers merely called these generic functions. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: remove CA debug code This looks like it is not necessary to have available for endusers who cannot patch kernels for bug reporting and tests of fixes. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: remove AV/C debug code This looks like it is not necessary to have available for endusers who cannot patch kernels for bug reporting and tests of fixes. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: remove various debug code Most of this was already commented out. And that which wasn't is not relevant in normal use. Mon, 29 Sep 2008 19:22:48 +0200 (CEST) firedtv: register input device as child of a FireWire device Instead of one virtual input device which exists for the whole lifetime of the driver and receives events from all connected FireDTVs, register one input device for each firedtv device. These input devices will show up as children of the respective firedtv devices in the sysfs hierarchy. However, the implementation falls short because of a bug in userspace: Udev's path_id script gets stuck with 100% CPU utilization, maybe because of an assumption about the maximum ieee1394 device hierarchy depth. To avoid this bug, we use the fw-host device instead of the proper unit_directory device as parent of the input device. There is hope that the port to the new firewire stack won't be inhibited by this userspace bug because there are no fw-host devices there. Mon, 29 Sep 2008 19:21:52 +0200 (CEST) firedtv: fix string comparison and a few sparse warnings Sparse found a bug: while ((kv_buf + kv_len - 1) == '\0') should have been while (kv_buf[kv_len - 1] == '\0') We fix it by a better implementation without a temporary copy. Also fix sparse warnings of 0 instead of NULL and signedness mismatches. Mon, 29 Sep 2008 19:21:20 +0200 (CEST) firedtv: remove unused struct members and redefine an int as a bool. Mon, 29 Sep 2008 19:20:36 +0200 (CEST) firedtv: fix initialization of dvb_frontend.ops There was a NULL pointer reference if no dvb_frontend_info was found. Also, don't directly assign struct typed values to struct typed variables. Instead write out assignments to individual strcut members. This reduces module size by about 1 kB. Mon, 29 Sep 2008 19:19:41 +0200 (CEST) firedtv: remove unused dual subunit code from initialization No FireDTVs with more than one subunit exists, hence simplify the initialization for the special case of one subunit. The driver was able to check for more than one subunit but was broken for more than two subunits. While we are at it, add several missing cleanups after failure, and include a few dynamically allocated structures diretly into struct firesat instead of allocating them separately. Mon, 29 Sep 2008 19:19:08 +0200 (CEST) firedtv: add vendor_id and version to driver match table Now that nodemgr was enhanced to match against the root directory's vendor ID if there isn't one in the unit directory, use this to prevent firedtv to be bound to wrong devices by accident. Also add the AV/C software version ID to the match flags for completeness; specifier ID and software only make sense as a pair. Mon, 29 Sep 2008 19:18:30 +0200 (CEST) firedtv: use hpsb_node_read(), _write(), _lock() because they are simpler and treat the node generation more correctly. While we are at it, clean up and simplify surrounding code. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
