* [TG3]: Speed up SRAM accessMichael Chan2006-03-28
| | | | | | | | | | | | | | | | | Speed up SRAM read and write functions if possible by using MMIO instead of config. cycles. With this change, the post reset signature done at the end of D3 power change must now be moved before the D3 power change. IBM reported a problem on powerpc blades during ethtool self test that was caused by the memory test taking excessively long. Config. cycles are very slow on powerpc and the memory test can take more than 10 seconds to complete using config. cycles. As a result, NETDEV WATCHDOG can be triggered during self test and the chip can end up in a funny state. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S.

* [TG3]: Fix bug in 40-bit DMA workaround codeMichael Chan2006-03-28

* [TG3]: Fix probe failure due to invalid MAC addressMichael Chan2006-03-28
| | | | | | | | | | | | | Some older bootcode in some devices may report 0 MAC address in SRAM when booting up from low power state. This patch fixes the problem by checking for a valid MAC address in SRAM and falling back to NVRAM if necessary.

* [TG3]: netif_carrier_off runs too early; could still be queued when init failsJeff Mahoney2006-03-21
| | | | | | | | | | | | | | | | | | | | | | Move the netif_carrier_off() call from tg3_init_one()-> tg3_init_link_config() to tg3_open() as is the convention for most other network drivers. I was getting a panic after a tg3 device failed to initialize due to DMA failure. The oops pointed to the link watch queue with spinlock debugging enabled. Without spinlock debugging, the Oops didn't occur. I suspect that the link event was getting queued but not executed until after the DMA test had failed and the device was freed. The link event was then operating on freed memory, which could contain anything. With this patch applied, the Oops no longer occurs. [ Based upon feedback from Michael Chan, we move netif_carrier_off() to the end of tg3_init_one() instead of moving it to tg3_open() -DaveM ] Signed-off-by: Jeff Mahoney <jeffm@suse.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: David S.

| | | | | | | | | | | | | Support 5787 hardware TSO using a new flag TG3_FLG2_HW_TSO_2. Since the TSO interface is slightly different and these chips have finally fixed the 4GB DMA problem and do not have the 40-bit DMA problem, a new hard_start_xmit is used for these chips. All previous chips will use the old hard_start_xmit that is now renamed tg3_start_xmit_dma_bug(). Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Change the power state parameter to pci_power_t type and use constants defined in pci.h. Certain ethtool operations cannot be performed after tg3_close() because the device will go to low power state. Add return -EAGAIN in such cases where appropriate.

| * [TG3]: 40-bit DMA workaround part 2Michael Chan2006-03-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | 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. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
