Subject: [PATCHSET #upstram-fixes] libata-acpi: improve ACPI corner case handling
Date: Fri, 14 Dec 2007 15:15:32 +0900 [thread overview]
Message-ID: <11976129411285-git-send-email-htejun@gmail.com> (raw)
Hello,
This patchset contains the following patches to improve ACPI corner
case handling.
0001-libata-drop-const-from-struct-ata_port-param-on-ata.patch
0002-libata-update-ata_-_printk-macros-such-that-level.patch
0003-libata-add-more-opcodes-to-ata.h.patch
0004-libata-implement-ata_acpi_init_gtm.patch
0005-libata-use-init_gtm-in-ata_acpi_cbl_80wire.patch
0006-libata-acpi-improve-ACPI-disabling.patch
0007-libata-acpi-improve-_GTF-execution-error-handling-a.patch
0008-libata-acpi-ignore-_GTM-failure-during-suspend.patch
0009-libata-acpi-implement-_GTF-command-filtering-and-fi.patch
The first three patches are misc prep patches.
0004-0005 backport init_gtm from #upstream to fix ACPI evaluation
failure on some boards and fix ACPI cable detection.
0006-0008 improve ATA ACPI corner case / error handling. With these
changes, most ACPI errors don't cause slow down or other side effects
for probing and suspend/resuming.
0009 implements command filtering such that certain _GTF commands are
filtered. Filtering can be controlled with kernel parameter.
Currently only lock / freeze lock commands are filtered out.
This fixes all reported ATA ACPI related regressions. There can be
cases where _GTM evaluation explodes but it doesn't affect operation
at all and the correct solution seems to be suppress those messages.
Thanks.
