| * [PATCH] drivers/net/amd8111e.c: fix NAPI interrupt in pollLiu Tao2005-05-121-10/+14
| | | | | | | | | | | | | | | | | | This patch makes the netif_rx_complete() and rx_interrupt_enable atomic when exiting the poll() method, so to avoid interrupt in poll. It also fixes the rx interrupt check logic in interrupt handler. Signed-off-by: Liu Tao <liutao1980@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

| | | | | | | | | | | | | | | | | | The 'if' clause for ULI526X in tulip_mdio_write allows for spin_unlock_irqrestore to be called twice for tp->mii_lock.

* | [TG3]: Set minimal hw interrupt mitigation.David S. Miller2005-05-182-14/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: David S. Miller <davem@davemloft.net>
* | [TG3]: Add tagged status support.David S. Miller2005-05-182-55/+142
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Based upon valuable feedback from Michael Chan <mchan@broadcom.com> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | Version 2 of the 3com OfficeConnect 11g Cardbus Card aka 3CRWE154G72 is not supported by the prism54 project. To stop confusion, the kernel documentation should state so as 3com made a good job hiding the version.
