Subject: [BUG] acpi_hw_[enable|disable]_non_wakeup_gpe_block
Date: Sat, 14 Feb 2004 23:17:37 +0100 [thread overview]
Message-ID: <200402142317.41033.a.malysh@centrium.de> (raw)
Hi all,
I have found a bug? in linux acpi that values within gpe_register_info are
overwritten. Please see these values (note: only system_io gpe_register were
dumped):
1) system go into S1
Feb 14 23:01:08 rose kernel:
acpi_hw_disable_non_wakeup_gpe_block:gpe_block(0xcef335c8)
gpe_register_info(0xcefec548) gpe_register_info->wake_enable=0x0
gpe_register_info->enable_address=0x1022 gpe_register_info->enable=0x11
Feb 14 23:01:08 rose kernel:

gpe_register_info->enable_address=0x1023 gpe_register_info->enable=0x5d
Feb 14 23:01:08 rose kernel:
acpi_hw_disable_non_wakeup_gpe_block:gpe_block(0xcef33568)
gpe_register_info(0xcefec4c8) gpe_register_info->wake_enable=0x0

gpe_register_info(0xcefec4e4) gpe_register_info->wake_enable=0x0
gpe_register_info->enable_address=0x1033 gpe_register_info->enable=0x0
2) system wakeup
Feb 14 23:01:08 rose kernel:

gpe_register_info(0xcefec564) gpe_register_info->wake_enable=0x0

Feb 14 23:01:08 rose kernel:
acpi_hw_disable_non_wakeup_gpe_block:gpe_block(0xcef33568)
gpe_register_info(0xcefec4e4) gpe_register_info->wake_enable=0x0
gpe_register_info->enable_address=0x1033 gpe_register_info->enable=0x0
As you can see, io_addr 0x1022 and 0x1023 were restored with wrong values.
any thoughts or patches to try?
