ACPICA: Tables: Add new table events indicating table installation/uninstallation

2016-09-10T00:43:01Z

ACPICA commit ed6a5fbc694f3a27d93014391aa9a6f6fe490461 This patch adds 2 new table events to indicate table installation/uninstallation. Currently, as ACPICA never uninstalls tables, this patch thus only adds table handler invocation for the table installation event. Lv Zheng. The 2 events are to be used to fix a sysfs table handling issue related to LoadTable opcode (see Link # [1] below). The actual sysfs fixing code is not included, the sysfs fixes will be sent as separate patches.

ACPICA: Clib: Eliminate acpi_os_XXXFile()/acpi_log_error and link clibrary fxxx()/errno/perror() instead

2016-08-13T01:12:32Z

ACPICA commit 189429fb7d06cdb89043ae32d615faf553467f1d This patch follows new ACPICA design, eliminates old portable OSLs, and implements fopen/fread/fwrite/fclose/fseek/ftell for GNU EFI environment. This patch also eliminates acpi_log_error(), convering them into fprintf(stderr)/perror(). Lv Zheng.

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

2016-08-13T01:09:33Z

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

2016-05-05T13:14:35Z

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: Revert "acpi_get_object_info: Add support for ACPI 5.0 _SUB method."

2016-01-01T02:47:35Z

ACPICA commit e4743959b59ad93eab7310adf756adc930be0ddb This reverts commit 8e7a8753827660c3dd1f571f3185610402b756f0. The _SUB method was found to be problematic for this interface because some implementations use control methods. Therefore, it is being removed. Operations cannot be used because this interface is called during the device discovery scan and the region handlers are not fully installed at that time.
