2022-07-18drm/amdkfd: add SPM support for SVMAlex Sierra1-13/+21
When CPU is connected throug XGMI, it has coherent access to VRAM resource. In this case that resource is taken from a table in the device gmc aperture base. This resource is used along with the device type, which could be DEVICE_PRIVATE or DEVICE_COHERENT to create the device page map region. Also, MIGRATE_VMA_SELECT_DEVICE_COHERENT flag is selected for coherent type case during migration to device.

2022-07-14amdgpu: disable powerpc support for the newer display engineLinus Torvalds1-1/+1
The DRM_AMD_DC_DCN display engine support (Raven, Navi, and newer) has not been building cleanly on powerpc and causes link errors due to mixing hard- and soft-float object files: powerpc64-linux-ld: drivers/gpu/drm/amd/amdgpu/../display/dc/dml/display_mode_lib.o uses hard float, drivers/gpu/drm/amd/amdgpu/../display/dc/dcn31/dcn31_resource.o uses soft float powerpc64-linux-ld: failed to merge target specific data of file drivers/gpu/drm/amd/amdgpu/../display/dc/dcn31/dcn31_resource.o [..] and while patches are floating around, it's not exactly obvious what is going on. The problem bisects to commit 41b7a347bf14 ("powerpc: Book3S 64-bit outline-only KASAN support") but that is probably more about changing config variables than the fundamental cause. Despite the bisection result, a more directly related commit seems to be 26f4712aedbd ("drm/amd/display: move FPU related code from dcn31 to dml/dcn31 folder"). It's probably a combination of the two. This has been going on since the merge window, without any final word. So instead of blindly applying patches that may or may not be the right thing, let's disable this for now. As Michael Ellerman says: "IIUIC this code was never enabled on ppc before, so disabling it seems like a reasonable fix to get the build clean" and once we have more actual feedback (and find any potential users) we can always re-enable it with the patch that fixes the issues and back-port as necessary.

2022-07-14drm/amdgpu: Check BO's requested pinning domains against its preferred_domainsLeo Li1-0/+4
When pinning a buffer, we should check to see if there are any additional restrictions imposed by bo->preferred_domains. This will prevent the BO from being moved to an invalid domain when pinning. For example, this can happen if the user requests to create a BO in GTT domain for display scanout. amdgpu_dm will allow pinning to either VRAM or GTT domains, since DCN can scanout from either or. However, in amdgpu_bo_pin_restricted(), pinning to VRAM is preferred if there is adequate carveout. This can lead to pinning to VRAM despite the user requesting GTT placement for the BO. v2: Allow the kernel to override the domain, which can happen when exporting a BO to a V4L camera (for example).

2022-07-13drm/amd/display: Only use depth 36 bpp linebuffers on DCN display engines.Mario Kleiner1-5/+6
Various DCE versions had trouble with 36 bpp lb depth, requiring fixes, last time in commit 353ca0fa5630 ("drm/amd/display: Fix 10bit 4K display on CIK GPUs") for DCE-8. So far >= DCE-11.2 was considered ok, but now I found out that on DCE-11.2 it causes dithering when there shouldn't be any, so identity pixel passthrough with identity gamma LUTs doesn't work when it should. This breaks various important neuroscience applications, as reported to me by scientific users of Polaris cards under Ubuntu 22.04 with Linux 5.15, and confirmed by testing it myself on DCE-11.2. Lets only use depth 36 for DCN engines, where my testing showed that it is both necessary for high color precision output, e.g., RGBA16 fb's, and not harmful, as far as more than one year in real-world use showed. DCE engines seem to work fine for high precision output at 30 bpp, so this ("famous last words") depth 30 should hopefully fix all known problems without introducing new ones. Successfully retested on DCE-11.2 Polaris and DCN-1.0 Raven Ridge on top of Linux 5.19.0-rc2 + drm-next.

2:1 combine [Why] With single display odm 2:1 policy, when moving windowed MPO across the display, we experience a momentary lag when we move between the centre of the display and the right half of the display. This is caused by the MPO pipe being reallocated when it crosses this boundary [How] Handle two cases: 1. if the head pipe has a MPO pipe already allocated in the old context, then use that pipe if it is available in the current context 2. if the head pipe is on the left side, check the right side to see if it has a MPO pipe already allocated. If so, don't use that pipe if it is selected as the idle pipe in the current context Add new function pointer called .acquire_idle_pipe_for_head_pipe that will pass in the head pipe and handle case 1 Add find_idle_secondary_pipe_check_mpo() to handle case 2 if we don't hit case 1. In dc_add_plane_to_context(), start with head pipe and check case 1 and 2 in call acquire_free_pipe_for_head(). If we are on the right side of the display, check case 1 again by passing in right side pipe as the new head in call acquire_free_pipe_for_head().

[Why&How] Add a field to store the DCN IP offset for use with runtime offset calculation This offset is indexed using reg*_BASE_IDX for the corresponding group of registers. For example, address of DIG_BE_CNTL instance 0 is calculated like: dcn_reg_offsets[regDIG0_DIG_BE_CNTL_BASE_IDX] + regDIG0_DIG_BE_CNTL. {dcn,nbio}_reg_offsets are used only for the ASICs for which runtime initializaion of offsets are enabled through the modified SR* macros that contain an additional REG_STRUCT element in the macro definition. DCN3.5+ will fail dc_create() if {dcn,nbio}_reg_offsets are null. They are applicable starting with DCN32/321 and are not used for ASICs upstreamed before them. ASICs before DCN32/321 will not contain any computation that involves {dcn,nbio}_reg_offsets. For them, the address/offset computation is done during compile time. This is evident from the BASE_INNER definition for compile time vs run time initialization: Compile time init: #define BASE_INNER(seg) DCN_BASE__INST0_SEG ## seg Run time init: #define BASE_INNER(seg) ctx->dcn_reg_offsets[seg] BASE_INNER macro is local to each dcnxx_resource.c and hence different ASICs can have either runtime or compile time initialization of offsets. The computation of offset is done for registers all at once during driver load and hence it does not introduce any performance overhead during normal operation.

[Why] ABGR16161616 colour format was added to dcn10/20/30, and set any ARGB16161616 to the same value as it (26). As such, the HDR10 Green Point y value was too far off of the EDID stated value for DisplayPort. [How] Added back the pixel format as 22 for ARGB16161616 for dcn10/20/30.

2022-07-13drm/amd/display: update DML1 logic for unbounded req handlingJun Lei2-0/+18
[why] Unbounded request logic in resource/DML has some issues where unbounded request is being enabled incorrectly. SW today enables unbounded request unconditionally in hardware, on the assumption that HW can always support it in single pipe scenarios. This worked until now because the same assumption is made in DML. A new DML update is needed to fix a bug, where there are single pipe scenarios where unbounded cannot be enabled, and this change in DML needs to be ported in, and dcn32 resource logic fixed. [how] First, dcn32_resource should program unbounded req in HW according to unbounded req enablement output from DML, as opposed to DML input Second, port in DML1 update which disables unbounded req in some scenarios to fix an issue with poor stutter performance Reviewed-by: Nevenko Stupar <Nevenko.Stupar@amd.com> Reviewed-by: Dmytro Laktyushkin <Dmytro.Laktyushkin@amd.com> Acked-by: Solomon Chiu <solomon.chiu@amd.com> Signed-off-by: Jun Lei <jun.lei@amd.com> Tested-by: Daniel Wheeler <daniel.wheeler@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
