ACPI: video: Prefer native over vendor

2023-01-07T10:11:42Z

[ Upstream commit fb1836c91317e0770950260dfa91eb9b2170cb27 ] When available prefer native backlight control over vendor backlight control. Testing has shown that there are quite a few laptop models which rely on native backlight control (they don't have ACPI video bus backlight control) and on which acpi_osi_is_win8() returns false. Currently __acpi_video_get_backlight_type() returns vendor on these laptops, leading to an empty /sys/class/backlight. As a workaround for this acpi_video_backlight_use_native() has been temporarily changed to always return true. This re-introduces the problem of having multiple backlight devices under /sys/class/backlight for a single panel. Change __acpi_video_get_backlight_type() to prefer native over vendor when available. So that it returns native on these models. And change acpi_video_backlight_use_native() back to only return true when __acpi_video_get_backlight_type() returns native. Signed-off-by: Hans de Goede Signed-off-by: Rafael J.

ACPI: video: Simplify __acpi_video_get_backlight_type()

2023-01-07T10:11:42Z

[ Upstream commit a5df42521f328b45c9d89c13740e747be08ac66e ] Simplify __acpi_video_get_backlight_type() removing a nested if which makes the flow harder to follow. This also results in having only 1 exit point with return acpi_backlight_native instead of 2. Note this drops the (video_caps & ACPI_VIDEO_BACKLIGHT) check from the if (acpi_osi_is_win8() && native_available) return native path. Windows 8's hardware certification requirements include that there must be ACPI video bus backlight control, so the ACPI_VIDEO_BACKLIGHT check is redundant.

ACPI: x86: s2idle: Stop using AMD specific codepath for Rembrandt+

2023-01-04T10:29:00Z

commit e555c85792bd5f9828a2fd2ca9761f70efb1c77b upstream. After we introduced a module parameter and quirk infrastructure for picking the Microsoft GUID over the SOC vendor GUID we discovered that lots and lots of systems are getting this wrong. The table continues to grow, and is becoming unwieldy. We don't really have any benefit to forcing vendors to populate the AMD GUID. This is just extra work, and more and more vendors seem to mess it up. As the Microsoft GUID is used by Windows as well, it's very likely that it won't be messed up like this. So drop all the quirks forcing it and the Rembrandt behavior. This means that Cezanne or later effectively only run the Microsoft GUID codepath with the exception of HP Elitebook 8*5 G9.

ACPI: x86: s2idle: Force AMD GUID/_REV 2 on HP Elitebook 865

2023-01-04T10:29:00Z

commit 3ea45390e9c0d35805ef8357ace55594fd4233d0 upstream. HP Elitebook 865 supports both the AMD GUID w/ _REV 2 and Microsoft GUID with _REV 0. Both have very similar code but the AMD GUID has a special workaround that is specific to a problem with spurious wakeups on systems with Qualcomm WLAN. This is believed to be a bug in the Qualcomm WLAN F/W (it doesn't affect any other WLAN H/W). If this WLAN firmware is fixed this quirk can be dropped.

ACPI: video: Fix Apple GMUX backlight detection

2023-01-04T10:28:51Z

[ Upstream commit 3cf3b7f012f3ea8bdc56196e367cf07c10424855 ] The apple-gmux driver only binds to old GMUX devices which have an IORESOURCE_IO resource (using inb()/outb()) rather then memory-mapped IO (IORESOURCE_MEM). T2 MacBooks use the new style GMUX devices (with IORESOURCE_MEM access), so these are not supported by the apple-gmux driver. This is not a problem since they have working ACPI video backlight support. But the apple_gmux_present() helper only checks if an ACPI device with the "APP000B" HID is present, causing acpi_video_get_backlight_type() to return acpi_backlight_apple_gmux disabling the acpi_video backlight device. Add a new apple_gmux_backlight_present() helper which checks that the "APP000B" device actually is an old GMUX device with an IORESOURCE_IO resource. This fixes the acpi_video0 backlight no longer registering on T2 MacBooks. Note people are working to add support for the new style GMUX to Linux: https://github.com/kekrby/linux-t2/commits/wip/hybrid-graphics Once this lands this patch should be reverted so that acpi_video_get_backlight_type() also prefers the gmux on new style GMUX MacBooks, but for now this is necessary to avoid regressing backlight control on T2 Macs.
