ACPICA: Events: Stop unconditionally clearing ACPI IRQs during suspend/resume

2018-03-18T17:51:59+00:00

Unconditionally clearing ACPI IRQs during suspend/resume can lead to unexpected IRQ losts. This patch fixes this issue by removing such IRQ clearing code. If this patch triggers regression, the regression should be in the GPE handlers that cannot correctly determine some spurious triggered events as no-ops. Please report any regression related to this commit to the ACPI component on kernel bugzilla. Lv Zheng.

ACPICA: Events: Introduce acpi_mask_gpe() to implement GPE masking mechanism

2016-08-13T01:09:33+00:00

ACPICA commit 23a417ca406a527e7ae1710893e59a8b6db30e14 There is a facility in Linux, developers can control the enabling/disabling of a GPE via /sys/firmware/acpi/interrupts/gpexx. This is mainly for debugging purposes. But many users expect to use this facility to implement quirks to mask a specific GPE when there is a gap in Linux causing this GPE to flood. This is not working correctly because currently this facility invokes enabling/disabling counting based GPE driver APIs: acpi_enable_gpe()/acpi_disable_gpe() and the GPE drivers can still affect the count to mess up the GPE masking purposes. However, most of the IRQ chip designs allow masking/unmasking IRQs via a masking bit which is different from the enabled bit to achieve the same purpose. But the GPE hardware doesn't contain such a feature, this brings the trouble. In this patch, we introduce a software mechanism to implement the GPE masking feature, and acpi_mask_gpe() are provided to the OSPMs to mask/unmask GPEs in the above mentioned situation instead of acpi_enable_gpe()/acpi_disable_gpe().

ACPICA: Divergence: remove unwanted spaces for typedef

2016-05-05T13:14:35+00:00

ACPICA commit b2294cae776f5a66a7697414b21949d307e6856f This patch removes unwanted spaces for typedef. This solution doesn't cover function types. Note that the linuxize result of this commit is very giant and should have many conflicts against the current Linux upstream. Thus it is required to modify the linuxize result of this commit and the commits around it manually in order to have them merged to the Linux upstream. Since this is very costy, we should do this only once, and if we can't ensure to do this only once, we need to revert the Linux code to the wrong indentation result before merging the linuxize result of this commit.

ACPICA: Linuxize: reduce divergences for 20151218 release

2016-01-01T02:26:44+00:00

The patch reduces source code differences between the Linux kernel and the ACPICA upstream so that the linuxized ACPICA 20151218 release can be applied with reduced human intervention. The pscode.c has already been out of sync for months, and it becomes more and more difficult to merge pscode.c changes, so instead of update the affected lines of pscode.c, this patch synchronizes entire pscode.c file.
