72b845e04e [TG3]: Do not try to access NIC_SRAM_DATA_SIG on Sun parts.
Sun does't put an SEEPROM behind the tigon3 chip, among other things,
so accesses to these areas just give bus timeouts.

4a29cc2e50 [TG3]: 40-bit DMA workaround part 2
The 40-bit DMA workaround recently implemented for 5714, 5715, and
5780 needs to be expanded because there may be other tg3 devices
behind the EPB Express to PCIX bridge in the 5780 class device.

For example, some 4-port card or mother board designs have 5704 behind
the 5714.

All devices behind the EPB require the 40-bit DMA workaround.

Thanks to Chris Elmquist again for reporting the problem and testing
the patch.

72f2afb8a6 [TG3]: Add DMA address workaround
Add DMA workaround for chips that do not support full 64-bit DMA
addresses.

5714, 5715, and 5780 chips only support DMA addresses less than 40
bits. On 64-bit systems with IOMMU, set the dma_mask to 40-bit so
that pci_map_xxx() calls will map the DMA address below 40 bits if
necessary. On 64-bit systems without IOMMU, set the dma_mask to
64-bit and check for DMA addresses exceeding the limit in
tg3_start_xmit().

5788 only supports 32-bit DMA so need to set the mask appropriately
also.

Thanks to Chris Elmquist at SGI for reporting and helping to debug
the problem on 5714.

Thanks to David Miller for explaining the HIGHMEM and DMA stuff.

7faa006f94 [TG3]: Flush tg3_reset_task()
Make sure tg3_reset_task() is flushed in the close and suspend paths
as noted by Jeff Garzik.

In the close path, calling flush_scheduled_work() may cause deadlock
if linkwatch_event() is on the workqueue. linkwatch_event() will try
to get the rtnl_lock() which is already held by tg3_close(). So
instead, we set a flag in tg3_reset_task() and tg3_close() polls
the flag until it is cleared.

Change the ASF heart beat to 5 seconds for faster detection of system
crash. The driver sends the heartbeat every 2 seconds and the ASF

c94e39418a [TG3]: 5780 PHY fixes
Fix 5780 PHY related problems:

1. MAC_RX_MODE reset must be done before setting up the MAC_MODE
   register on 5705_PLUS chips or the chip will stop receiving after
   a while. The MAC_RX_MODE reset is needed to prevent intermittently
   losing the first receive packet on serdes chips.

2. Skip MAC loopback test on 5780 because of hardware errata. Normal
   traffic including PHY loopback is not affected by the errata.

3. PHY loopback fails intermittently on 5708S and this is fixed by
   putting the PHY in loopback mode first before programming the MAC
   mode register. A MAC_RX_MODE reset is also added.

4. Return -EINVAL in tg3_nway_reset() if device is in TBI mode. Allow
   nway_reset if 5780S is in parallel detect mode.

5. Add missing PHY IDs in KNOWN_PHY_ID() macro.

61487480dd [TG3]: Remove status block access in tg3_msi() and add prefetches
Remove unnecessary status block accesses in tg3_msi(). Since MSI is
not shared, it is unnecessary to read the status block to determine if
there are any new events in the MSI handler. It is also unnecessary to
clear the updated bit in the status block.

Since the poll list is per-cpu, tg3_poll() will be scheduled to run on
the same CPU that received the MSI. Prefetches for the status block
and the next rx descriptors are added in tg3_msi() to improve their
access times when tg3_poll() runs.

In the non-MSI irq handlers, we need to check the status block because
interrupts may be shared. Only prefetches for the next rx descriptors
are added.

6892914fb7 [TG3]: Add indirect register method for 5703 behind ICH
This patch adds the new workaround for 5703 A1/A2 if it is behind
certain ICH bridges. The workaround disables memory and uses config.
cycles only to access all registers. The 5702/03 chips can mistakenly
decode the special cycles from the ICH chipsets as memory write cycles,
causing corruption of register and memory space. Only certain ICH
bridges will drive special cycles with non-zero data during the address
phase which can fall within the 5703's address range. This is not an ICH
bug as the PCI spec allows non-zero address during special cycles.
However, only these ICH bridges are known to drive non-zero addresses
during special cycles.

The indirect_lock is also changed to spin_lock_irqsave from spin_lock_bh
because it is used in irq handler when using the indirect method to
disable interrupts.

d4ef160889 [TG3]: Fix ethtool loopback test lockup
The tg3_abort_hw() call in tg3_test_loopback() is causing lockups on
some devices. tg3_abort_hw() disables the memory arbiter, causing
tg3_reset_hw() to hang when it tries to write the pre-reset signature.
tg3_abort_hw() should only be called after the pre-reset signature has
been written. This is all done in tg3_reset_hw() so the tg3_abort_hw()
call is unnecessary and can be removed.

[ Also bump driver version and release date. -DaveM ]

da6b2d01d6 [TG3]: Fix SerDes detection
A problem was reported by Grant Grundler on an HP rx8620 using IOX
Core LAN partno(A7109-6) 5701 copper NIC. The tg3 driver mistakenly
detects this NIC as having a SerDes PHY and link does not come up as a
result.

The problem was caused by an incorrectly programmed eeprom that set the
NIC_SRAM_DATA_CFG_PHY_TYPE_FIBER bit in the NIC_SRAM_DATA_CFG location.

This patch will override the NIC_SRAM_DATA_CFG_PHY_TYPE_FIBER bit if a
valid PHY ID is read from the MII registers on older 570x chips where
the MII interface is not used on SerDes chips. On newer chips such as
the 5780 that use MII for both copper and SerDes, SerDes detection must
rely on the eeprom.

This patch will make the SerDes detection identical to versions 3.25 and
older.

2. Remove the tg3_enable_ints() call in tg3_reset_hw(). Interrupts are

   prevent interrupts being enabled while poll is disabled.

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

15f9850d3c [TG3]: Set minimal hw interrupt mitigation.
Even though we do software interrupt mitigation
via NAPI, it still helps to have some minimal
hw assisted mitigation.

This helps, particularly, on systems where register
I/O overhead is much greater than the CPU horsepower.

For example, it helps on NUMA systems.  In such cases
the PIO overhead to disable interrupts for NAPI accounts
for the majority of the packet processing cost.  The
CPU is fast enough such that only a single packet is
processed by each NAPI poll call.

Thanks to Michael Chan for reviewing this patch.

fac9b83ea7 [TG3]: Add tagged status support.
When supported, use the TAGGED interrupt processing support
the chip provides.  In this mode, instead of a "on/off" binary
semaphore, an incrementing tag scheme is used to ACK interrupts.

All MSI supporting chips support TAGGED mode, so the tg3_msi()
interrupt handler uses it unconditionally.  This invariant is
verified when MSI support is tested.

Since we can invoke tg3_poll() multiple times per interrupt under
high packet load, we fetch a new copy of the tag value in the
status block right before we actually do the work.

Also, because the tagged status tells the chip exactly which
work we have processed, we can make two optimizations:

1) tg3_restart_ints() need not check tg3_has_work()
2) the tg3_timer() need not poke the chip 10 times per
   second to keep from losing interrupt events

04237dddd1 [TG3]: Fix tg3_restart_ints()
tg3_restart_ints() is called to re-enable interrupts after tg3_poll()
has finished all the work. It calls tg3_cond_int() to force an interrupt
if the status block updated bit is set. The updated bit will be set if
there is a new status block update sometime during tg3_poll() and it can
be very often. The worst part is that even if all the work has been
processed, the updated bit remains set and an interrupt will be forced
unnecessarily.

The fix is to call tg3_has_work() instead to determine if new work is
posted before forcing an interrupt. The way to force an interrupt is
also changed to use "coalesce_now" instead of "SETINT". The former is
generally a safer way to force the interrupt.

Also deleted the first parameter to tg3_has_work() which is unused.

rx work is determined by comparing tp->rx_rcb_ptr with the current hw

information in eeprom.

On the 5752, there are no pull-up resistors on the GPIO pins and it is
necessary to drive the unused GPIOs as output.

Linus Torvalds
1da177e4c3 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.

Let it rip!
