Subject: HID: quirks: Add Apple Magic Trackpad 2 to hid_have_special_driver
 list
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The Apple Magic Trackpad 2 is handled by the magicmouse driver. And
there were severe stability issues when both drivers (hid-generic and
hid-magicmouse) were loaded for this device.

Fixes: https://bugzilla.kernel.org/show_bug.cgi?id=210241

Subject: [PATCH] drm/amdgpu: don't limit gtt size on apus

Since commit 24562523688b ("Revert "drm/amd/amdgpu: set gtt size
according to system memory size only""), the GTT size was limited by
3GiB or VRAM size.

This is problematic on APU systems with a small carveout
(notably, those that ship with dGPUs where this is unconfigurable),
where the carveout size can be as low as 128MiB.

This makes it so the GTT size heuristic always uses 3/4ths of
the system memory size on APUs (limiting the size by 3GiB/VRAM size
only on devices with dedicated video memory).

Fixes: 24562523688b ("Revert drm/amd/amdgpu: set gtt size according to
system memory size only")
