* [BNX2]: Use CPU native page sizeMichael Chan2006-06-18
| | | | | | | | | | | | | Use CPU native page size to determine various ring sizes. This allows order-0 memory allocations on all systems. Added check to limit the page size to 16K since that's the maximum rx ring size that will be used. This will prevent using unnecessarily large page sizes on some architectures with large page sizes.

* [BNX2]: Add firmware decompressionMichael Chan2006-06-18
| | | | | | | | | | | Add functions to decompress firmware before loading to the internal CPUs. Compressing the firmware reduces the driver size significantly. Added file name length sanity check in the gzip header to prevent going past the end of buffer [suggested by DaveM]. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* [BNX2]: Combine small mem allocationsMichael Chan2006-03-23
| | | | | | | | | | | | Combine two small (56 byte and 320 byte) pci consistent memory allocations into one allocation. Jeff Garzik suggested to store the combined size in the bp structure for later use when freeing the memory. Use kzalloc() instead of kmalloc() + memset().

* [BNX2]: Fix link change handlingMichael Chan2006-03-23
| | | | | | | | | | | Fix some link-related problems by doing a coalesce_now after link change interrupt to flush out the transient link status. To facilitate this, the host coalesce cmd register value is cached in the device structure. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* [BNX2]: include <linux/vmalloc.h>Michael Chan2006-03-20

* [BNX2]: Support larger rx ring sizes (part 1)Michael Chan2006-03-20
| | | | | | | | | | | | | | | | | | | | Increase maximum receive ring size from 255 to 1020 by supporting up to 4 linked pages of receive descriptors. To accomodate the higher memory usage, each physical descriptor page is allocated separately and the software ring that keeps track of the SKBs and the DMA addresses is allocated using vmalloc. Some of the receive-related fields in the bp structure are re- organized a bit for better locality of reference. The max. was reduced to 1020 from 4080 after discussion with David Miller. This patch contains ring init code changes only. This next patch contains rx data path code changes. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S.

* [BNX2]: Fix UDP checksum verificationMichael Chan2006-01-23
| | | | | | | | | | | | Fix TCP/UDP checksum verification. Use status bits in the buffer descriptor instead of the checksum value to verify rx checksum. Using the checksum value will be incorrect if the UDP packet has zero in the UDP checksum field. Firmware update required for this fix.

* [BNX2]: Fix VLAN on ASFMichael Chan2006-01-23

* [PATCH] bnx2: refine bnx2_pollMichael Chan2005-11-05
| | | | | | | | | | | | | | | Refine bnx2_poll() logic to write back the most up-to-date status tag when all work has been processed. This eliminates some occasional extra interrupts when a older status tag is written even though all work has been processed. The idea is to read the status tag just before exiting bnx2_poll() and then check again for any new work. If no new work is pending, the status tag written back will not generate any extra interrupt. This logic is similar to the changes David Miller did to tg3_poll(). Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* [PATCH] bnx2: update firmware handshake for 5708Michael Chan2005-11-05

* [BNX2]: Fix bug in irq handler and add prefetchMichael Chan2005-09-08
| | | | | | | | | | | | | | | | Fix bug in bnx2_interrupt() that caused an unnecessary register read. The BNX2_PCICFG_MISC_STATUS should only be read when the status tag has not changed. Add prefetch of the status block in bnx2_msi() similar to tg3_msi(). The status block is not touched in bnx2_msi() and prefetching it will speed up bnx2_poll() that will run on the same CPU that received the MSI. Update version.

* [BNX2]: remove atomics in txMichael Chan2005-08-29
| | | | | | | | | | | | | Remove atomic operations in the fast tx path. Expensive atomic operations were used to keep track of the number of available tx descriptors. The new code uses the difference between the consumer and producer index to determine the number of free tx descriptors. As suggested by Jeff Garzik, the name of the inline function is changed to all lower case. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* [BNX2]: speedup serdes linkupMichael Chan2005-08-29
| | | | | | | | | | | | | | | | | | | | | | This speeds up link-up time on 5706 SerDes if the link partner does not autoneg, a rather common scenario in blade servers. Some blade servers use IPMI for keyboard input and it's important to minimize link disruptions. The speedup is achieved by shortening the timer to (HZ / 3) during the transient period right after initiating a SerDes autoneg. If autoneg does not complete, parallel detect can be done sooner. After the transient period is over, the timer goes back to its normal HZ interval. As suggested by Jeff Garzik, the timer initialization is moved to bnx2_init_board() from bnx2_open(). An eeprom bit is also added to allow default forced SerDes speed for even faster link-up time. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* [BNX2]: Fix rtnl deadlock in bnx2_closeMichael Chan2005-08-29
| | | | | | | | | | | | | | | | | | This fixes an rtnl deadlock problem when flush_scheduled_work() is called from bnx2_close(). In rare cases, linkwatch_event() may be on the workqueue from a previous close of a different device and it will try to get the rtnl lock which is already held by dev_close(). The fix is to set a flag if we are in the reset task which is run from the workqueue. bnx2_close() will loop until the flag is cleared. As suggested by Jeff Garzik, the loop is changed to call msleep(1) instead of yield() in the original patch. flush_scheduled_work() is also moved to bnx2_remove_one() before the netdev is freed.
