From: Dan Williams Date: Fri, 23 Feb 2007 23:36:43 +0000 (-0700) Subject: sata_vsc: refactor vsc_sata_interrupt and hook up error handling X-Git-Tag: v2.6.21-rc2~25^2~10 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ea34e45a4670c4fa0da3442fc74789fd66c1201b;p=pandora-kernel.git sata_vsc: refactor vsc_sata_interrupt and hook up error handling 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 Signed-off-by: Dan Williams Signed-off-by: Jeff Garzik --- Reading git-diff-tree failed
