Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it.

[PATCH] Remove more unnecessary driver printk's As I promised last week, here is the first pass at removing all unnecessary printk's that exist in network device drivers currently in promiscuous mode. The duplicate messages are not needed so they have been removed. Some of these drivers are quite old and might not need an update, but I did them all anyway. I am currently auditing the remaining conditional printk's and will send out a patch for those soon. Signed-off-by: Andy Gospodarek <andy@greyhouse.net> Signed-off-by: Jeff Garzik <jeff@garzik.org>

/*
Theory of Operation
I. Board Compatibility
This device driver is designed for the AMD 79C960, the "PCnet-ISA
single-chip ethernet controller for ISA". This chip is used in a wide
variety of boards from vendors such as Allied Telesis, HP, Kingston,
and Boca. This driver is also intended to work with older AMD 7990
designs, such as the NE1500 and NE2100, and newer 79C961. For convenience,
I use the name LANCE to refer to all of the AMD chips, even though it properly
refers only to the original 7990.
II. Board-specific settings
The driver is designed to work the boards that use the faster
bus-master mode, rather than in shared memory mode. (Only older designs
have on-board buffer memory needed to support the slower shared memory mode.)
Most ISA boards have jumpered settings for the I/O base, IRQ line, and DMA
channel. This driver probes the likely base addresses:
{0x300, 0x320, 0x340, 0x360}.
After the board is found it generates a DMA-timeout interrupt and uses
autoIRQ to find the IRQ line. The DMA channel can be set with the low bits
of the otherwise-unused dev->mem_start value (aka PARAM1). If unset it is
probed for by enabling each free DMA channel in turn and checking if
initialization succeeds.
The HP-J2405A board is an exception: with this board it is easy to read the
EEPROM-set values for the base, IRQ, and DMA. (Of course you must already
_know_ the base address -- that field is for writing the EEPROM.)
III. Driver operation
IIIa. Ring buffers
The LANCE uses ring buffers of Tx and Rx descriptors. Each entry describes
the base and length of the data buffer, along with status bits. The length
of these buffers is set by LANCE_LOG_{RX,TX}_BUFFERS, which is log_2() of
the buffer length (rather than being directly the buffer length) for
implementation ease. The current values are 2 (Tx) and 4 (Rx), which leads to
ring sizes of 4 (Tx) and 16 (Rx). Increasing the number of ring entries
needlessly uses extra space and reduces the chance that an upper layer will
be able to reorder queued Tx packets based on priority. Decreasing the number
of entries makes it more difficult to achieve back-to-back packet transmission
and increases the chance that Rx ring will overflow. (Consider the worst case
of receiving back-to-back minimum-sized packets.)
The LANCE has the capability to "chain" both Rx and Tx buffers, but this driver
statically allocates full-sized (slightly oversized -- PKT_BUF_SZ) buffers to
avoid the administrative overhead. For the Rx side this avoids dynamically
allocating full-sized buffers "just in case", at the expense of a
memory-to-memory data copy for each packet received. For most systems this
is a good tradeoff: the Rx buffer will always be in low memory, the copy
is inexpensive, and it primes the cache for later packet processing. For Tx
the buffers are only used when needed as low-memory bounce buffers.
IIIB. 16M memory limitations.
For the ISA bus master mode all structures used directly by the LANCE,
the initialization block, Rx and Tx rings, and data buffers, must be
accessible from the ISA bus, i.e. in the lower 16M of real memory.
This is a problem for current Linux kernels on >16M machines. The network
devices are initialized after memory initialization, and the kernel doles out
memory from the top of memory downward. The current solution is to have a
special network initialization routine that's called before memory
initialization; this will eventually be generalized for all network devices.
As mentioned before, low-memory "bounce-buffers" are used when needed.
IIIC. Synchronization
The driver runs as two independent, single-threaded flows of control. One
is the send-packet routine, which enforces single-threaded use by the
dev->tbusy flag. The other thread is the interrupt handler, which is single
threaded by the hardware and other software.
The send packet thread has partial control over the Tx ring and 'dev->tbusy'
flag. It sets the tbusy flag whenever it's queuing a Tx packet. If the next
queue slot is empty, it clears the tbusy flag when finished otherwise it sets
the 'lp->tx_full' flag.
The interrupt handler has exclusive control over the Rx ring and records stats
from the Tx ring. (The Tx-done interrupt can't be selectively turned off, so
we can't avoid the interrupt overhead by having the Tx routine reap the Tx
stats.) After reaping the stats, it marks the queue entry as empty by setting
the 'base' to zero. Iff the 'lp->tx_full' flag is set, it clears both the
tx_full and tbusy flags.
*/
/* Set the number of Tx and Rx buffers, using Log_2(# buffers).
Reasonable default values are 16 Tx buffers, and 16 Rx buffers.
That translates to 4 and 4 (16 == 2^^4).
This is a compile-time option for efficiency.

static int lance_rx(struct net_device *dev);
IRQ: Maintain regs pointer globally rather than passing to IRQ handlers Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.

[NET]: Remove gratuitous use of skb->tail in network drivers. Many drivers use skb->tail unnecessarily. In these situations, the code roughly looks like: dev = dev_alloc_skb(...); [optional] skb_reserve(skb, ...); ... skb->tail ... But even if the skb_reserve() happens, skb->data equals skb->tail. So it doesn't make any sense to use anything other than skb->data in these cases. Another case was the s2io.c driver directly mucking with the skb->data and skb->tail pointers. It really just wanted to do an skb_reserve(), so that's what the code was changed to do instead. Another reason I'm making this change as it allows some SKB cleanups I have planned simpler to merge. In those cleanups, skb->head, skb->tail, and skb->end pointers are removed, and replaced with skb->head_room and skb->tail_room integers. Signed-off-by: David S.

[NET]: Avoid allocating skb in skb_pad First of all it is unnecessary to allocate a new skb in skb_pad since the existing one is not shared. More importantly, our hard_start_xmit interface does not allow a new skb to be allocated since that breaks requeueing. This patch uses pskb_expand_head to expand the existing skb and linearize it if needed. Actually, someone should sift through every instance of skb_pad on a non-linear skb as they do not fit the reasons why this was originally created. Incidentally, this fixes a minor bug when the skb is cloned (tcpdump, TCP, etc.). As it is skb_pad will simply write over a cloned skb. Because of the position of the write it is unlikely to cause problems but still it's best if we don't do it. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

/* The LANCE interrupt handler. */
IRQ: Maintain regs pointer globally rather than passing to IRQ handlers Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.
