* drm/amd/display: Enable vblank interrupt during CRC captureNicholas Kazlauskas2019-04-052-22/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit 428da2bdb05d76c48d0bd8fbfa2e4c102685be08 ] [Why] In order to read CRC events when CRC capture is enabled the vblank interrput handler needs to be running for the CRTC. The handler is enabled while there is an active vblank reference. When running IGT tests there will often be no active vblank reference but the test expects to read a CRC value. This is valid usage (and works on i915 since they have a CRC interrupt handler) so the reference to the vblank should be grabbed while capture is active. This issue was found running: igt@kms_plane_multiple@atomic-pipe-b-tiling-none The pipe-b is the only one in the initial commit and was not previously active so no vblank reference is grabbed. The vblank interrupt is not enabled and the test times out. [How] Keep a reference to the vblank as long as CRC capture is enabled. If userspace never explicitly disables it then the reference is also dropped when removing the CRTC from the context (stream = NULL).

* drm/amd/display: Disconnect mpcc when changing tgNicholas Kazlauskas2019-04-051-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit 77476360f173c127c191bfe8ca8113130ef283b8 ] [Why] This fixes an mpc programming error for the following sequence of atomic commits when pipe split is enabled: Commit 1: CRTC0 (plane 4, plane 3) Pipe 0: old_plane_state = A0, new_plane_state = A1, new_tg = T0 Pipe 1: old_plane_state = B0, new_plane_state = B1, new_tg = T0 Pipe 2: old_plane_state = A0, new_plane_state = A1, new_tg = T0 Pipe 3: old_plane_state = B0, new_plane_state = B1, new_tg = T0 Commit 2: CRTC0 (plane 3), CRTC1 (plane 2) Pipe 0: old_plane_state = A1, new_plane_state = A2, new_tg = T0 Pipe 1: old_plane_state = B1, new_plane_state = B2, new_tg = T1 Pipe 2: old_plane_state = A1, new_plane_state = NULL, new_tg = NULL Pipe 3: old_plane_state = B1, new_plane_state = NULL, new_tg = NULL In the second commit the assertion for mpcc in use is hit because mpcc disconnect never occurs for pipe 1. This is because the stream changes for pipe 1 and the opp_list is empty. This sequence occurs when running the "igt@kms_plane_multiple@atomic-pipe-A-tiling-none" test with two displays connected. [How] Expand the reset condition to include: "old_pipe_ctx->stream_res.tg != new_pipe_ctx->stream_res.tg" ...but only when the plane state is non-NULL for both old and new.

* drm/amd/display: Don't re-program planes for DPMS changesNicholas Kazlauskas2019-04-051-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit 5062b797db4103218fa00ee254417b8ecaab7401 ] [Why] There are opt1c lock warnings and CRTC read timeouts when running the "igt@kms_plane@plane-position-hole-dpms-pipe-*" tests. These are caused by trying to reprogram planes that are not in the current context. DPMS off removes the stream from the context. In this case: new_crtc_state->active_changed = true new_crtc_state->mode_changed = false The planes are reprogrammed before the stream is removed from the context because stream_state->mode_changed = false. For DPMS adds the stream and planes back to the context: new_crtc_state->active_changed = true new_crtc_state->mode_changed = false The planes are also reprogrammed here before the stream is added to the context because stream_state->mode_changed = true. They were not previously in the current context so warnings occur here. [How] Set stream_state->mode_changed = true when new_crtc_state->active_changed = true too. This prevents reprogramming before the context is applied in DC. The programming will be done after the context is applied.

* drm/amd/display: Fix reference counting for struct dc_sink.Mathias Fröhlich2019-04-053-8/+37

Thus make reference counting consistent for these members and just plain increment the reference count when the variable gets assigned and decrement when the pointer is set to zero or replaced. Also simplify reference counting in selected function sopes to be sure the reference is released in any case. In some cases add NULL pointer check before dereferencing. At a hand full of places a comment is placed to stat that the reference increment happened already somewhere else. This actually fixes the following kernel bug on my system when enabling display core in amdgpu. There are some more similar bug reports around, so it probably helps at more places. kernel BUG at mm/slub.c:294! invalid opcode: 0000 [#1] SMP PTI CPU: 9 PID: 1180 Comm: Xorg Not tainted 5.0.0-rc1+ #2 Hardware name: Supermicro X10DAi/X10DAI, BIOS 3.0a 02/05/2018 RIP: 0010:__slab_free+0x1e2/0x3d0 Code: 8b 54 24 30 48 89 4c 24 28 e8 da fb ff ff 4c 8b 54 24 28 85 c0 0f 85 67 fe ff ff 48 8d 65 d8 5b 41 5c 41 5d 41 5e 41 5f 5d c3 <0f> 0b 49 3b 5c 24 28 75 ab 48 8b 44 24 30 49 89 4c 24 28 49 89 44 RSP: 0018:ffffb0978589fa90 EFLAGS: 00010246 RAX: ffff92f12806c400 RBX: 0000000080200019 RCX: ffff92f12806c400 RDX: ffff92f12806c400 RSI: ffffdd6421a01a00 RDI: ffff92ed2f406e80 RBP: ffffb0978589fb40 R08: 0000000000000001 R09: ffffffffc0ee4748 R10: ffff92f12806c400 R11: 0000000000000001 R12: ffffdd6421a01a00 R13: ffff92f12806c400 R14: ffff92ed2f406e80 R15: ffffdd6421a01a20 FS: 00007f4170be0ac0(0000) GS:ffff92ed2fb40000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 0000562818aaa000 CR3: 000000045745a002 CR4: 00000000003606e0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 Call Trace: ? drm_dbg+0x87/0x90 [drm] dc_stream_release+0x28/0x50 [amdgpu] amdgpu_dm_connector_mode_valid+0xb4/0x1f0 [amdgpu] drm_helper_probe_single_connector_modes+0x492/0x6b0 [drm_kms_helper] drm_mode_getconnector+0x457/0x490 [drm] ? drm_connector_property_set_ioctl+0x60/0x60 [drm] drm_ioctl_kernel+0xa9/0xf0 [drm] drm_ioctl+0x201/0x3a0 [drm] ? drm_connector_property_set_ioctl+0x60/0x60 [drm] amdgpu_drm_ioctl+0x49/0x80 [amdgpu] do_vfs_ioctl+0xa4/0x630 ? __sys_recvmsg+0x83/0xa0 ksys_ioctl+0x60/0x90 __x64_sys_ioctl+0x16/0x20 do_syscall_64+0x5b/0x160 entry_SYSCALL_64_after_hwframe+0x44/0xa9 RIP: 0033:0x7f417110809b Code: 0f 1e fa 48 8b 05 ed bd 0c 00 64 c7 00 26 00 00 00 48 c7 c0 ff ff ff ff c3 66 0f 1f 44 00 00 f3 0f 1e fa b8 10 00 00 00 0f 05 <48> 3d 01 f0 ff ff 73 01 c3 48 8b 0d bd bd 0c 00 f7 d8 64 89 01 48 RSP: 002b:00007ffdd8d1c268 EFLAGS: 00000246 ORIG_RAX: 0000000000000010 RAX: ffffffffffffffda RBX: 0000562818a8ebc0 RCX: 00007f417110809b RDX: 00007ffdd8d1c2a0 RSI: 00000000c05064a7 RDI: 0000000000000012 RBP: 00007ffdd8d1c2a0 R08: 0000562819012280 R09: 0000000000000007 R10: 0000000000000000 R11: 0000000000000246 R12: 00000000c05064a7 R13: 0000000000000012 R14: 0000000000000012 R15: 00007ffdd8d1c2a0 Modules linked in: nfsv4 dns_resolver nfs lockd grace fscache fuse vfat fat amdgpu intel_rapl sb_edac x86_pkg_temp_thermal intel_powerclamp coretemp kvm_intel kvm irqbypass crct10dif_pclmul chash gpu_sched crc32_pclmul snd_hda_codec_realtek ghash_clmulni_intel amd_iommu_v2 iTCO_wdt iTCO_vendor_support ttm snd_hda_codec_generic snd_hda_codec_hdmi ledtrig_audio snd_hda_intel drm_kms_helper snd_hda_codec intel_cstate snd_hda_core drm snd_hwdep snd_seq snd_seq_device intel_uncore snd_pcm intel_rapl_perf snd_timer snd soundcore ioatdma pcspkr intel_wmi_thunderbolt mxm_wmi i2c_i801 lpc_ich pcc_cpufreq auth_rpcgss sunrpc igb crc32c_intel i2c_algo_bit dca wmi hid_cherry analog gameport joydev This patch is based on agd5f/drm-next-5.1-wip.

* drm/amd/display: Use vrr friendly pageflip throttling in DC.Mario Kleiner2019-02-272-4/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In VRR mode, keep track of the vblank count of the last completed pageflip in amdgpu_crtc->last_flip_vblank, as recorded in the pageflip completion handler after each completed flip. Use that count to prevent mmio programming a new pageflip within the same vblank in which the last pageflip completed, iow. to throttle pageflips to at most one flip per video frame, while at the same time allowing to request a flip not only before start of vblank, but also anywhere within vblank. The old logic did the same, and made sense for regular fixed refresh rate flipping, but in vrr mode it prevents requesting a flip anywhere inside the possibly huge vblank, thereby reducing framerate in vrr mode instead of improving it, by delaying a slightly delayed flip requests up to a maximum vblank duration + 1 scanout duration. This would limit VRR usefulness to only help applications with a very high GPU demand, which can submit the flip request before start of vblank, but then have to wait long for fences to complete. With this method a flip can be both requested and - after fences have completed - executed, ie. it doesn't matter if the request (amdgpu_dm_do_flip()) gets delayed until deep into the extended vblank due to cpu execution delays. This also allows clients which want to regulate framerate within the vrr range a much more fine-grained control of flip timing, a feature that might be useful for video playback, and is very useful for neuroscience/vision research applications. In regular non-VRR mode, retain the old flip submission behavior. This to keep flip scheduling for fullscreen X11/GLX OpenGL clients intact, if they use the GLX_OML_sync_control extensions glXSwapBufferMscOML(, ..., target_msc,...) function with a specific target_msc target vblank count. glXSwapBuffersMscOML() or DRI3/Present PresentPixmap() will not flip at the proper target_msc for a non-zero target_msc if VRR mode is active with this patch. They'd often flip one frame too early. However, this limitation should not matter much in VRR mode, as scheduling based on vblank counts is pretty futile/unusable under variable refresh duration anyway, so no real extra harm is done.

* drm/amd/display: Fix negative cursor pos programmingNicholas Kazlauskas2019-02-201-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [Why] If the cursor pos passed from DM is less than the plane_state->dst_rect top left corner then the unsigned cursor pos wraps around to a large positive number since cursor pos is a u32. There was an attempt to guard against this in hubp1_cursor_set_position by checking the src_x_offset and src_y_offset and offseting the cursor hotspot within hubp1_cursor_set_position. However, the cursor position itself is still being programmed incorrectly as a large value. This manifests itself visually as the cursor disappearing or containing strange artifacts near the middle of the screen on raven. [How] Don't subtract the destination rect top left corner from the pos but add it to the hotspot instead. This happens before the pos gets passed into hubp1_cursor_set_position. This achieves the same result but avoids the subtraction wrap around. With this fix the original cursor programming logic can be used again.

* drm/amdgpu: Transfer fences to dmabuf importerChris Wilson2019-01-301-8/+51
| | | | | | | | | | | | | | | | | | | | | | | | | | | | amdgpu only uses shared-fences internally, but dmabuf importers rely on implicit write hazard tracking via the reservation_object.fence_excl. For example, the importer use the write hazard for timing a page flip to only occur after the exporter has finished flushing its write into the surface. As such, on exporting a dmabuf, we must either flush all outstanding fences (for we do not know which are writes and should have been exclusive) or alternatively create a new exclusive fence that is the composite of all the existing shared fences, and so will only be signaled when all earlier fences are signaled (ensuring that we can not be signaled before the completion of any earlier write). v2: reservation_object is already locked by amdgpu_bo_reserve() v3: Replace looping with get_fences_rcu and special case the promotion of a single shared fence directly to an exclusive fence, bypassing the fence array. v4: Drop the fence array ref after assigning to reservation_object Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=107341 Testcase: igt/amd_prime/amd-to-i915 References: 8e94a46c1770 ("drm/amdgpu: Attach exclusive fence to prime exported bo's.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | [Why] This fixes a stuttering issue that occurs when moving a hardware cursor when VRR is enabled. Previously when VRR is enabled atomic check will grab the connector state for every atomic update. This has to lock the connector in order to do so. The locking is bad enough by itself for performance, but it gets worse with what we do just below that - add all the planes for the CRTC to the commit. This prevents the cursor fast path from working - there's more than one plane now. With state->allow_modeset = true on top of this, it also adds and removes all the planes from the DC context triggering a full (very slow) update in DC. [How] We need the connector state to get the VRR min/max capbilities, but we only need them when there's a CRTC mode change or when VRR is toggled. The condition has been updated accordingly.
