[TG3]: Refinements to new locking strategy. · bbe832c0

由 Michael Chan 提交于 6月 24, 2005

1. Move tp->irq_sync = 0 to before the interrupt mailbox IO in
   tg3_enable_ints() so that the interrupt handler will always see
   irq_sync == 0 when interrupts are enabled.

2. Remove the tg3_enable_ints() call in tg3_reset_hw(). Interrupts are
   always enabled explicitly or through tg3_netif_start(). This is to
   prevent interrupts being enabled while poll is disabled.

3. Update trans_start with jiffies in tg3_netif_stop() to prevent false
   NETDEV WATCHDOG.

4. Pass in the proper irq_sync parameter to tg3_full_lock() depending on
   netif_running() in some of the ethtool set calls.

[TG3]: Eliminate all hw IRQ handler spinlocks. · f47c11ee

由 David S. Miller 提交于 6月 24, 2005

Move all driver spinlocks to be taken at sw IRQ
context only.

This fixes the skb_copy() we were doing with hw
IRQs disabled (which is illegal and triggers a
BUG() with HIGHMEM enabled).  It also simplifies
the locking all over the driver tremendously.

We accomplish this feat by creating a special
sequence to synchronize with the hw IRQ handler
using a binary state and synchronize_irq().
This idea is from Herbert Xu.

Thanks to Michael Chan for helping to track down
all of the race conditions in initial versions
of this code.

[TG3]: Fix missing memory barriers and SD_STATUS_UPDATED bit clearing. · cd024c8b

由 David S. Miller 提交于 6月 24, 2005

There must be a rmb() between reading the status block tag
and calling tg3_has_work().  This was missing in tg3_mis()
and tg3_interrupt_tagged().  tg3_poll() got it right.

Also, SD_STATUS_UPDATED must be cleared in the status block
right before we call tg3_has_work().  Only tg3_poll() got this
wrong.

Based upon patches and commentary from Grant Grundler and
Michael Chan.

[TCP]: Do not present confusing congestion control options by default. · a6484045

由 David S. Miller 提交于 6月 24, 2005

Create TCP_CONG_ADVANCED option, akin to IP_ADVANCED_ROUTER, which
when disabled will bypass all of the congestion control Kconfig
options and leave the user with a safe default.

That safe default is currently BIC-TCP with new Reno as a fallback.

[PATCH] ARM: 2748/1: ixp2000 implementation of the iomap api · 2966207c

由 Lennert Buytenhek 提交于 6月 24, 2005

Patch from Lennert Buytenhek

A number of ixp2000 models have a bug where the byte lanes for PCI I/O
transactions are swapped.  We already work around this in our versions
of {in,out}{b,w,l}, but we also need to perform these workarounds in a
custom implementation of the new iomap API, provided in this patch.

This patch conditionalises the io{read,write}{8,16,32} defines and the
prototypes for ioport_map/ioport_unmap in asm-arm/io.h on ioread8 not
already having been defined.  This is done so that platforms can provide
their own implementation of the iomap API, ixp2000 for example needs
this.

由 Catalin Marinas 提交于 6月 24, 2005

Patch from Catalin Marinas

cpu_v6_set_pte() sets the kernel access rights to r/o for user
pages (L_PTE_USER) when neither L_PTE_WRITE nor L_PTE_DIRTY are
set. This causes a kernel data abort when writing the TLS value
in the 0xffff0000 page. This patch enables the kernel r/w access.

Current IXP4xx debug macros do not work in the small window between
the MMU being enabled and the call to map_io() b/c the standard

UART specifically for use with the debug macros.

Add "memory" clobbers to the x86 inline asm of strncmp and friends · 793ae774

由 Linus Torvalds 提交于 6月 24, 2005

They don't actually clobber memory, but gcc doesn't even know they
_read_ memory, so can apparently re-order memory accesses around them.

Which obviously does the wrong thing if the memory access happens to
change the memory that the compare function is accessing..

Verified to fix a strange boot problem by Jens Axboe.
