2024-10-14drm/msm: Allocate memory for disp snapshot with kvzalloc()Douglas Anderson1-2/+2
With the "drm/msm: add a display mmu fault handler" series [1] we saw issues in the field where memory allocation was failing when allocating space for registers in msm_disp_state_dump_regs(). Specifically we were seeing an order 5 allocation fail. It's not surprising that order 5 allocations will sometimes fail after the system has been up and running for a while. There's no need here for contiguous memory. Change the allocation to kvzalloc() which should make it much less likely to fail.

2024-10-14drm/msm: Avoid NULL dereference in msm_disp_state_print_regs()Douglas Anderson1-7/+8
If the allocation in msm_disp_state_dump_regs() failed then `block->state` can be NULL. The msm_disp_state_print_regs() function _does_ have code to try to handle it with: if (*reg) dump_addr = *reg; ...but since "dump_addr" is initialized to NULL the above is actually a noop. The code then goes on to dereference `dump_addr`. Make the function print "Registers not stored" when it sees a NULL to solve this. Since we're touching the code, fix msm_disp_state_print_regs() not to pointlessly take a double-pointer and properly mark the pointer as `const`.

2024-10-14drm/msm/dsi: fix 32-bit signed integer extension in pclk_rate calculationJonathan Marek1-1/+1
When (mode->clock * 1000) is larger than (1<<31), int to unsigned long conversion will sign extend the int to 64 bits and the pclk_rate value will be incorrect. Fix this by making the result of the multiplication unsigned. Note that above (1<<32) would still be broken and require more changes, but its unlikely anyone will need that anytime soon.

2024-10-14drm/msm/dpu: move CRTC resource assignment to dpu_encoder_virt_atomic_checkDmitry Baryshkov2-24/+38
Historically CRTC resources (LMs and CTLs) were assigned in dpu_crtc_atomic_begin(). The commit 9222cdd27e82 ("drm/msm/dpu: move hw resource tracking to crtc state") simply moved resources to struct dpu_crtc_state, without changing the code sequence. Later on the commit b107603b4ad0 ("drm/msm/dpu: map mixer/ctl hw blocks in encoder modeset") rearanged the code, but still kept the cstate->num_mixers assignment to happen during commit phase. This makes dpu_crtc_state inconsistent between consequent atomic_check() calls. Move CRTC resource assignment to happen at the end of dpu_encoder_virt_atomic_check().

2024-09-02drm/msm/dpu: Configure DP INTF/PHY selectorDmitry Baryshkov4-6/+72
Some platforms provides a mechanism for configuring the mapping between (one or two) DisplayPort intfs and their PHYs. In particular SC8180X requires this to be configured, since on this platform there are fewer controllers than PHYs. The change implements the logic for optionally configuring which PHY each of the DP INTFs should be connected to and marks the SC8180X DPU to program 2 entries. For now the request is simply to program the mapping 1:1, any support for alternative mappings is left until the use case arrise. Note that e.g. msm-4.14 unconditionally maps INTF 0 to PHY 0 on all platforms, so perhaps this is needed in order to get DisplayPort working on some other platforms as well.

2024-09-01drm/msm/a5xx: workaround early ring-buffer emptiness checkVladimir Lypak3-0/+9
There is another cause for soft lock-up of GPU in empty ring-buffer: race between GPU executing last commands and CPU checking ring for emptiness. On GPU side IRQ for retire is triggered by CACHE_FLUSH_TS event and RPTR shadow (which is used to check ring emptiness) is updated a bit later from CP_CONTEXT_SWITCH_YIELD. Thus if GPU is executing its last commands slow enough or we check that ring too fast we will miss a chance to trigger switch to lower priority ring because current ring isn't empty just yet. This can escalate to lock-up situation described in previous patch. To work-around this issue we keep track of last submit sequence number for each ring and compare it with one written to memptrs from GPU during execution of CACHE_FLUSH_TS event.

2024-09-01drm/msm/a5xx: fix races in preemption evaluation stageVladimir Lypak2-2/+23
On A5XX GPUs when preemption is used it's invietable to enter a soft lock-up state in which GPU is stuck at empty ring-buffer doing nothing. This appears as full UI lockup and not detected as GPU hang (because it's not). This happens due to not triggering preemption when it was needed. Sometimes this state can be recovered by some new submit but generally it won't happen because applications are waiting for old submits to retire. One of the reasons why this happens is a race between a5xx_submit and a5xx_preempt_trigger called from IRQ during submit retire. Former thread updates ring->cur of previously empty and not current ring right after latter checks it for emptiness. Then both threads can just exit because for first one preempt_state wasn't NONE yet and for second one all rings appeared to be empty. To prevent such situations from happening we need to establish guarantee for preempt_trigger to make decision after each submit or retire. To implement this we serialize preemption initiation using spinlock. If switch is already in progress we need to re-trigger preemption when it finishes.

Two fields of preempt_record which are used by CP aren't reset on resume: "data" and "info". This is the reason behind faults which happen when we try to switch to the ring that was active last before suspend. In addition those faults can't be recovered from because we use suspend and resume to do so (keeping values of those fields again).

2024-09-01drm/msm/a5xx: disable preemption in submits by defaultVladimir Lypak1-2/+6
Fine grain preemption (switching from/to points within submits) requires extra handling in command stream of those submits, especially when rendering with tiling (using GMEM). However this handling is missing at this point in mesa (and always was). For this reason we get random GPU faults and hangs if more than one priority level is used because local preemption is enabled prior to executing command stream from submit. With that said it was ahead of time to enable local preemption by default considering the fact that even on downstream kernel it is only enabled if requested via UAPI.

2024-09-01drm/msm/adreno: Assign msm_gpu->pdev earlier to avoid nullptrsKonrad Dybcio2-1/+1
There are some cases, such as the one uncovered by Commit 46d4efcccc68 ("drm/msm/a6xx: Avoid a nullptr dereference when speedbin setting fails") where msm_gpu_cleanup() : platform_set_drvdata(gpu->pdev, NULL); is called on gpu->pdev == NULL, as the GPU device has not been fully initialized yet. Turns out that there's more than just the aforementioned path that causes this to happen (e.g. the case when there's speedbin data in the catalog, but opp-supported-hw is missing in DT). Assigning msm_gpu->pdev earlier seems like the least painful solution to this, therefore do so.

2024-08-30drm/msm: Fix incorrect file name output in adreno_request_fw()Aleksandr Mishin1-1/+1
In adreno_request_fw() when debugging information is printed to the log after firmware load, an incorrect filename is printed. 'newname' is used instead of 'fwname', so prefix "qcom/" is being added to filename. Looks like "copy-paste" mistake. Fix this mistake by replacing 'newname' with 'fwname'. Found by Linux Verification Center (linuxtesting.org) with SVACE.

2024-08-30drm/msm: Fix UBWC macrotile_mode for a680Connor Abbott1-0/+3
Make it match the MDSS settings for sc8180x and downstream. Note that without the previous commit that exposes the value of macrotile_mode to mesa, this will break mesa which expects the legacy default value of 0. Therefore we do *not* want to backport it.

2024-08-30drm/msm: Expand UBWC config settingConnor Abbott3-17/+53
According to downstream we should be setting RBBM_NC_MODE_CNTL to a non-default value on a663 and a680, we don't support a663 and on a680 we're leaving it at the wrong (suboptimal) value. Just set it on all GPUs. Similarly, plumb through level2_swizzling_dis which will be necessary on a663. ubwc_mode is expanded and renamed to ubwc_swizzle to match the name on the display side. Similarly macrotile_mode should match the display side.
