Now that its possible for the first region to be non-zero we need to check to see if the new region should be added at the head and if so actually add it.

It is okay for most setups because bus-frequency is equal to clock-frequency. The problem emerges when cpu frequency is > 66MHz, quoting u-boot/cpu/mpc8xx/speed.c: if (gd->cpu_clk <= 66000000) { sccr_reg |= SCCR_EBDF00; /* bus division factor = 1 */ gd->bus_clk = gd->cpu_clk; } else { sccr_reg |= SCCR_EBDF01; /* bus division factor = 2 */ gd->bus_clk = gd->cpu_clk / 2; } So in case of cpu clock > 66MHz, bus_clk = cpu_clk / 2. An then, from Linux, we calculate timebase frequency as tb_freq = bus_clk / 16, that is cpu_clk / 2 / 16, which is wrong. This fixes the system time drifting problem on the EP885C board running at 133MHz.

In particular, + PCI and I/O devices have been reinitialized and are + in a clean, consistent state. +-- As the dump is performed, the dumped memory becomes + immediately available to the system for normal use. +-- After the dump is completed, no further reboots are + required; the system will be fully usable, and running + in it's normal, production mode on it normal kernel. + +The above can only be accomplished by coordination with, +and assistance from the hypervisor. The procedure is +as follows: + +-- When a system crashes, the hypervisor will save + the low 256MB of RAM to a previously registered + save region. It will also save system state, system + registers, and hardware PTE's. + +-- After the low 256MB area has been saved, the + hypervisor will reset PCI and other hardware state. + It will *not* clear RAM. It will then launch the + bootloader, as normal. + +-- The freshly booted kernel will notice that there + is a new node (ibm,dump-kernel) in the device tree, + indicating that there is crash data available from + a previous boot. It will boot into only 256MB of RAM, + reserving the rest of system memory. + +-- Userspace tools will parse /sys/kernel/release_region + and read /proc/vmcore to obtain the contents of memory, + which holds the previous crashed kernel. The userspace + tools may copy this info to disk, or network, nas, san, + iscsi, etc. as desired. + + For Example: the values in /sys/kernel/release-region + would look something like this (address-range pairs). + CPU:0x177fee000-0x10000: HPTE:0x177ffe020-0x1000: / + DUMP:0x177fff020-0x10000000, 0x10000000-0x16F1D370A + +-- As the userspace tools complete saving a portion of + dump, they echo an offset and size to + /sys/kernel/release_region to release the reserved + memory back to general use. + + An example of this is: + "echo 0x40000000 0x10000000 > /sys/kernel/release_region" + which will release 256MB at the 1GB boundary. + +Please note that the hypervisor-assisted dump feature +is only available on Power6-based systems with recent +firmware versions. + +Implementation details: +---------------------- + +During boot, a check is made to see if firmware supports +this feature on this particular machine. If it does, then +we check to see if a active dump is waiting for us. If yes +then everything but 256 MB of RAM is reserved during early +boot. This area is released once we collect a dump from user +land scripts that are run. If there is dump data, then +the /sys/kernel/release_region file is created, and +the reserved memory is held. + +If there is no waiting dump data, then only the highest +256MB of the ram is reserved as a scratch area. This area +is *not* released: this region will be kept permanently +reserved, so that it can act as a receptacle for a copy +of the low 256MB in the case a crash does occur. See, +however, "open issues" below, as to whether +such a reserved region is really needed. + +Currently the dump will be copied from /proc/vmcore to a +a new file upon user intervention. The starting address +to be read and the range for each data point in provided +in /sys/kernel/release_region. + +The tools to examine the dump will be same as the ones +used for kdump. + +General notes: +-------------- +Security: please note that there are potential security issues +with any sort of dump mechanism. In particular, plaintext +(unencrypted) data, and possibly passwords, may be present in +the dump data. Userspace tools must take adequate precautions to +preserve security. + +Open issues/ToDo: +------------ + o The various code paths that tell the hypervisor that a crash + occurred, vs. it simply being a normal reboot, should be + reviewed, and possibly clarified/fixed. + + o Instead of using /sys/kernel, should there be a /sys/dump + instead? There is a dump_subsys being created by the s390 code, + perhaps the pseries code should use a similar layout as well. + + o Is reserving a 256MB region really required? The goal of + reserving a 256MB scratch area is to make sure that no + important crash data is clobbered when the hypervisor + save low mem to the scratch area. But, if one could assure + that nothing important is located in some 256MB area, then + it would not need to be reserved. Something that can be + improved in subsequent versions. + + o Still working the kdump team to integrate this with kdump, + some work remains but this would not affect the current + patches. + + o Still need to write a shell script, to copy the dump away. + Currently I am parsing it manually.

The now obsolete linux,network-index properties are removed from the corresponding device trees. This won't break backwards compatiblity, because in cases where this fixup code is relevant, the device tree is part of the kernel image. The references to linux,network-index are removed from booting-without-of.txt. Not only is it now deprecated, but as a hack applicable only when the device tree blob and fixup code were in the same image, this property never belonged in booting-without-of.txt which describes the interface between the kernel and firmware or bootloaders which produce a device tree. By the time the device tree reaches the kernel, all the MAC addresses must be fully filled in.

We re-initialize all ports again, even though this has been done in the bootloader (U-Boot) before. This way we make sure, that we always run the latest init code in Linux and don't depend on code versions from U-Boot. Unfortunately all IBM/AMCC chips currently supported in this PCIe driver need a different reset-/init-sequence. Tested on AMCC Canyonlands eval board.

From 4c58f8fe2e84ba76a4bef01cbd987b5ce62771c3 Mon Sep 17 00:00:00 2001 From: Stephen Neuendorffer Date: Tue, 18 Mar 2008 04:36:31 +1100 Subject: [PATCH 052/202] [POWERPC] Xilinx: hwicap: Verify sync before reading idcode. It appears that in some cases, the sync word might not be recognized by the hardware correctly. If this happens, then attempting to read from the port results in an unrecoverable error because of the design of the FPGA core. This patch updates the code to check the status of the device before reading the IDCODE, in order to avoid entering this unrecoverable state. This patch also adds additional NOOP commands into the sychronization sequence, which appears to be necessary to avoid the condition on some hardware.

It introduces a common 4xx SoC file (sysdev/ppc4xx_soc.c) which currently "only" adds the L2 cache init code. Other common 4xx stuff can be added later here. The L2 cache handling code is a copy of Eugene's code in arch/ppc with small modifications. Tested on AMCC Taishan 440GX.

While the core dumps notes have correct contents, they have the wrong names, as the file descriptors used to generate the note names are off-by-one. An application that opens a SPE context as fd 3, the current core dump code will generate notes like: SPU/4/mem SPU/4/regs etc. This confuses GDB, which knows it is looking for SPE context 3 (from parsing the spu_context_run system call arguments), and cannot find any notes that match context 3. This change corrects the file descriptor counting, to only increment the fd until after we've written the note name.

This should never happen, but if it does, we try to print a nice oops message. That doesn't work, however, because the code at unrecov_slb assumes that the MMU has been turned on, but we call it with the MMU off (and have done so since the SLB miss handler was rewritten to run without turning the MMU on) -- except on iSeries, where everything runs with the MMU on. This fixes it by adding the necessary code to turn the MMU on if necessary.

Each block contains a single register bank containing the registers for up to three ports interleaved within that bank. This patch updates the PowerPC OF to platform_device glue code to support multiple silicon blocks, each with up to three ethernet ports. The main difference is that we now allow multiple mv64x60_shared platform_devices to be registered and we provide each port platform_device with a pointer to its associated shared platform_device. The pointer will not be used until the mv643xx_eth driver changes are committed.

Miller" Date: Mon, 24 Mar 2008 20:50:48 +1100 Subject: [PATCH 120/202] [LMB] Add lmb_alloc_nid() A variant of lmb_alloc() that tries to allocate memory on a specified NUMA node 'nid' but falls back to normal lmb_alloc() if that fails. The caller provides a 'nid_range' function pointer which assists the allocator. It is given args 'start', 'end', and pointer to integer 'this_nid'. It places at 'this_nid' the NUMA node id that corresponds to 'start', and returns the end address within 'start' to 'end' at which memory assosciated with 'nid' ends. This callback allows a platform to use lmb_alloc_nid() in just about any context, even ones in which early_pfn_to_nid() might not be working yet. This function will be used by the NUMA setup code on sparc64, and also it can be used by powerpc, replacing it's hand crafted "careful_allocation()" function in arch/powerpc/mm/numa.c If x86 ever converts it's NUMA support over to using the LMB helpers, it can use this too as it has something entirely similar.

It fixes the whitespace and formatting a bit, gets rid of a local DBG macro and uses the equivalent pr_debug instead, and restructures one while loop that had a function call and assignment in the condition to be a bit more readable. Some comments about functions being called with relocation disabled were also removed as they would just be confusing to most readers now that the code is in lib/.

In fact it probably isn't possible to hit the bug in practice since it would only occur in the situation where we can't satisfy the allocation request and there is a reserved region starting at 0. This fixes the potential bug by breaking out of the loop when we get to the point where the base of the reserved region is less than the size requested. This also restructures the loop to be a bit easier to follow. The same logic got copied into lmb_alloc_nid_unreserved, so this makes a similar change there. Here the bug is more likely to be hit because the outer loop (in lmb_alloc_nid) goes through the memory regions in increasing order rather than decreasing order as __lmb_alloc_base does, and we are therefore more likely to hit the case where we are testing against a reserved region with a base address of 0.

e92716f2aa68cdfbf6ec24d6f31f08b072e1a246 Mon Sep 17 00:00:00 2001 From: Jerone Young Date: Sat, 12 Apr 2008 05:03:33 +1000 Subject: [PATCH 125/202] [POWERPC] 4xx: Add idle wait support for 44x platforms This changes the cpu_idle loop for 44x platforms to utilize the Wait Enable feature of the CPU. This helps virtulization solutions know when the guest Linux kernel is in an idle state. A command line option called "idle" is also added to allow people to change the idle loop back to the original variation. This is done by setting "idle=spin" on the kernel command line.

It also initializes the softirq stack preempt_count to 0 instead of SOFTIRQ_OFFSET, like x86, as __do_softirq() does the increment, and we hit some lockdep checks if we have it twice. That means we do run for a little while off the softirq stack with the preempt-count set to 0, which could be deadly if we try to take a softirq at that point, however we do so with interrupts disabled, so I think we are ok.

With one exception -- because 'CHRP' still appears on the 'machine:' line in /proc/cpuinfo, the installer misdetects the platform and misconfigures yaboot, putting it into a PReP boot partition instead of in the /boot filesystem where the Efika's firmware could find it. The kernel's fixups for Efika already correct one instance of 'chrp', in the 'device_type' property. This fixes it in the 'CODEGEN,description' property too, since that's what's exposed to userspace in /proc/cpuinfo.

For the sub-arches that support relocatable interrupt vectors (book-e), it's reasonable to have memory start at a non-zero physical address. For those cases use the variable memstart_addr instead of the #define PPC_MEMSTART since the only uses of PPC_MEMSTART are for initialization and in the future we can set memstart_addr at runtime to have a relocatable kernel.

If the start of memory is at 0 it happens that total_lowmem can be used as both the size and the address that lowmem ends at (or more specifically one byte beyond the end). To make the code a bit more clear and deal with the case when the start of memory isn't at physical 0, we introduce lowmem_end_addr that represents one byte beyond the last physical address in the lowmem region.

Currently we reserve 256MB only. With this change, the code first checks to see if an amount has been specified on the boot command line with the "phyp_dump_reserve_size" option, and if so, uses that much. Otherwise it computes 5% of total ram and rounds it down to a multiple of 256MB, and uses the larger of that or 256MB. This is for large systems with a lot of memory (10GB or more). The aim is to have more space available for the kernel on reboot on machines with more resources. Although the dump will be collected pretty fast and the memory released really early on allowing the machine to have the full memory available, this alleviates any issues that can be caused by having way too little memory on very very large systems during those few minutes.

This trips up if you use "netconsole=foo" on the command line, and has the result that you get _only_ the netconsole, because the hvc device is never added as a preferred console. Worse still if you get the netconsole configuration wrong somehow, you end up with no console at all. As it turns out we don't need to worry about checking the command line. If the user has specified "console=foo", then foo will be set as the preferred console when the command line is parsed in start_kernel(), much later than the pseries code, and so the latter setting will take effect.

To allow for a dynamic kernel to support machines of either type we want to be able to compile in the interrupt handling code for both exception levels. Towards this goal we renamed the debug handling macros to specify the interrupt level in their name (DEBUG_CRIT_EXCEPTION/DebugCrit and DEBUG_DEBUG_EXCEPTION/DebugDebug). Additionally, on the Freescale Book-e parts we expanded the exception stacks to cover the maximum case of needing three exception stacks (normal, machine check and debug). There is some kernel text space optimization to be gained if a kernel is configured for a specific Freescale implementation but we aren't handling that now to allow for the single kernel image support.

This patch allocates parameter RAM for SMC serial ports without relying on previous initialisation by a boot loader or a wrapper layer. SMC parameter RAM on CPM2-based platforms can be allocated anywhere in the general-purpose areas of the dual-port RAM. The current code relies on the boot loader to allocate a section of general-purpose CPM RAM and gets the section address from the device tree. This patch modifies the device tree address usage to reference the SMC parameter RAM base pointer instead of a pre-allocated RAM section and allocates memory from the CPM dual-port RAM when initialising the SMC port. CPM1-based platforms are not affected.

This patch adds a new generic device tree processing function that retrieves virtual reg addresses from the device tree to the bootwrapper code. It also updates the bootwrapper code to use the new function. dt_get_virtual_reg() retrieves the virtual reg addresses from the "virtual-reg" property. If the property can't be found, it uses the "reg" property and walks the tree to translate it to absolute addresses.

This patch implements few routines so drivers could work with UPMs in safe and generic manner. So far there is just one user of these routines: Freescale UPM NAND driver.

Also, we switch to using DBCR0_IDM to determine if the user space app is being debugged as its a more consistent way. In the future we should support features like hardware breakpoint and watchpoints which will have DBCR0_IDM set but not necessarily DBCR0_IC (single step).

86xx: Add device tree source for Wind River SBC8641D This adds in the device tree source for the SBC8641D, based largely on the mpc8641_hpcn.dts. The biggest differences are the lack of a complex IRQ mapping (since no Uli/i8259 cascade) and the different layout of devices on the localbus node.

MPC8315 Reference Manual says: "The USB DR unit must have the same clock ratio as the encryption core unit, unless one of them has its clock disabled." The encryption core also drives I2C clock, so it is enabled and is equal to 01. That means USBDRCM should be 01 here. Plus, according to MPC8315E-RDB schematics, USB unit consumes CLK_IN clock from the 24.00MHz oscillator, which means we must adjust REFSEL bits as well. p.s. Idially we should rework whole 83xx/usb.c code, in two steps: 1. Move SCCR code to the U-Boot; 2. Implement fsl,usb-clock property in the device tree, so usb.c could decide what clock exactly to use on per-board basis. Though, today we're not in a hurry since there is just one 8315e board out there.

The combination of those two can thus deadlock. While some of those cases of interrupt read lock could be fixed (such as caching the RTAS tokens) I figured that taking the lock for writing is so rare (device-tree modification) that we may as well penalize that case and allow reading from interrupts. Thus, this turns all the writers to take the lock with irqs masked to avoid the situation.
