drm/amdgpu: Fix GPU TLB update error when PAGE_SIZE > AMDGPU_PAGE_SIZE

commit d53751568359e5b3ffb859b13cbd79dc77a571f1 upstream. When PAGE_SIZE is larger than AMDGPU_PAGE_SIZE, the number of GPU TLB entries which need to update in amdgpu_map_buffer() should be multiplied by AMDGPU_GPU_PAGES_IN_CPU_PAGE (PAGE_SIZE / AMDGPU_PAGE_SIZE).

drm/amd/display: Fix two cursor duplication when using overlay

2021-05-22T09:40:54+00:00

[ Upstream commit 16e9b3e58bc3fce7391539e0eb3fd167cbf9951f ] Our driver supports overlay planes, and as expected, some userspace compositor takes advantage of these features. If the userspace is not enabling the cursor, they can use multiple planes as they please. Nevertheless, we start to have constraints when userspace tries to enable hardware cursor with various planes. Basically, we cannot draw the cursor at the same size and position on two separated pipes since it uses extra bandwidth and DML only run with one cursor. For those reasons, when we enable hardware cursor and multiple planes, our driver should accept variations like the ones described below: +-------------+ +--------------+ | +---------+ | | | | |Primary | | | Primary | | | | | | Overlay | | +---------+ | | | |Overlay | | | +-------------+ +--------------+ In this scenario, we can have the desktop UI in the overlay and some other framebuffer attached to the primary plane (e.g., video). However, userspace needs to obey some rules and avoid scenarios like the ones described below (when enabling hw cursor): +--------+ |Overlay | +-------------+ +-----+-------+ +-| |--+ | +--------+ | +--------+ | | +--------+ | | |Overlay | | |Overlay | | | | | | | | | | | | | | +--------+ | +--------+ | | | | Primary | | Primary | | Primary | +-------------+ +-------------+ +-------------+ +-------------+ +-------------+ | +--------+ | Primary | | |Overlay | | | | | | | | | +--------+ | +--------+ | | Primary | | |Overlay | | +-------------+ +-| |--+ +--------+ If the userspace violates some of the above scenarios, our driver needs to reject the commit; otherwise, we can have unexpected behavior. Since we don't have a proper driver validation for the above case, we can see some problems like a duplicate cursor in applications that use multiple planes. This commit fixes the cursor issue and others by adding adequate verification for multiple planes. Change since V1 (Harry and Sean): - Remove cursor verification from the equation.

drm/amd/display: Initialize attribute for hdcp_srm sysfs file

commit fe1c97d008f86f672f0e9265f180c22451ca3b9f upstream. It is stored in dynamically allocated memory, so sysfs_bin_attr_init() must be called to initialize it. (Note: "initialization" only sets the .attr.key member in this struct; it does not change the value of any other members.) Otherwise, when CONFIG_DEBUG_LOCK_ALLOC=y this message appears during boot: BUG: key ffff9248900cd148 has not been registered!
