* spidernet: transmit raceLinas Vepstas2007-02-27
| | | | | | | | | | | Multiple threads performing a transmit can race into the spidernet tx ring cleanup code. This puts the relevant check under a lock.

* spidernet: fix racy double-free of skbLinas Vepstas2007-02-27
| | | | | | | | | | | | It appears that under certain circumstances, a race will result in a double-free of an skb. This patch null's out the skb pointer upon the skb free, avoiding the inadvertent deref of bogus data. The next patch fixes the actual race.

| | | | | | | | | | | | As of 2.6.20-git4, the spider_net driver does not compile. This appears to be due to some archaic usage involving kobjects.

* sungem_phy: support bcm5461 phy, autoneg.Jens Osterkamp2007-02-27
| | | | | | | | | | | | | | | | | | | | | | | | This version moves the medium variable to the card specific structure and changes the GMII_* to BCM54XX_* #defines. This patch adds improved version of enable_fiber for both the 5421 and the 5461 phy. It is now possible to specify with these wether you want autonegotiation or not. This is needed for bladecenter switches where some expect autonegotiation and some dont seem to like this at all. Depending on this flag it sets phy->autoneg accordingly for the fiber mode. More importantly it implements proper read_link and poll_link functions for both phys which can handle both copper and fiber mode by determining the medium first and then branching to the required functions. For fiber they all work fine, for copper they are not tested but return the result of the genmii_* function anyway which is supposed to work. The patch moves the genmii_* functions around to avoid foreward declarations.

| | | | | | | | | | | | | | | | | | | | | | IRQ mask bits assumed a 60xx or newer generation chip, which is very wrong for the 50xx series. Luckily both generations shared the per-port interrupt mask bits, leaving only the "misc chip features" bits to be completely mismatched. Fix 50xx by ensuring we only program bits that exist.

| * sata_promise: simplify port setupMikael Pettersson2007-02-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Each place in pdc_ata_init_one() that initialises a SATA port first calls pdc_ata_setup_port(), and then manually assigns the port's ->scr_addr. Simplify the code by extending pdc_ata_setup_port() to also handle scr_addr initialisation; for PATA ports we pass NULL as scr_addr. The initialisation of the PATA-only 20619 redundantly set up scr_addr for the ports. Remove this. Tested on 20619, 20575, and 20775 chips.

| * sata_vsc: refactor vsc_sata_interrupt and hook up error handlingDan Williams2007-02-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Separate sata_vsc interrupt handling into a normal (per-port) path and an error path with the addition of vsc_port_intr and vsc_error_intr respectively. The error path handles interrupt based hotplug events which requires the definition of vsc_freeze and vsc_thaw. Note: vsc_port_intr has a workaround for unexpected interrupts that occur during polled commands. This fixes a regression between 2.6.19 and 2.6.20. Changes in take2: * removed definition of invalid fis bit * let standard ata-error-handling handle the serror register * clear all unhandled interrupts * revert changes to vsc_intr_mask_update (vsc_thaw enables all interrupts) * use unlikely() for the pci-abort and not-our-interrupt cases in vsc_sata_interrupt Changes in take3: * Unify the "add" + "hook-up" patches into this single patch [htejun@gmail.com: clean up comments and suggestions] Cc: Jeremy Higdon <jeremy@sgi.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
| * sata_sil: ignore and clear spurious IRQs while executing commands by pollingTejun Heo2007-02-24
| | | | | | | | | | | | | | | | | | | | | | | | sata_sil used to trigger HSM error if IRQ occurs during polling command. This didn't matter because polling wasn't used in sata_sil. However, as of 2.6.20, all IDENTIFYs are performed by polling and device detection sometimes fails due to spurious IRQ. This patch makes sata_sil ignore and clear spurious IRQ while executing commands by polling. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | sata_nv implemented its own copies of the BMDMA helper functions for ADMA, since the ADMA BMDMA status registers are PIO while the other registers are MMIO, and this was the only way to handle this previously. Now that we have iomap support, the standard routines should just work, so use them. The only thing we need to override as far as ADMA and BMDMA is the post_internal_cmd callback, where we should only call ata_post_internal_cmd if we are in port-register mode.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (regenerated) SDB FIS containing spurious NCQ completions is a clear protocol violation. Currently, only some Maxtors with early firmware revisions are showing this problem. Those firmwares have other NCQ related problems including buggy NCQ error reporting and occasional lock up after NCQ errors. Consider spurious NCQ completions HSM violation and freeze the port after it. EH will turn off NCQ after this happens several times. Eventually drives which show this behavior should be blacklisted for NCQ. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
