Lockdep complains about an AA deadlock when rebooting the device. base-commit: 19c329f6 ============================================ WARNING: possible recursive locking detected 5.4.91 #1 Not tainted -------------------------------------------- reboot/5213 is trying to acquire lock: ffffff80d13391b0 (&kms->commit_lock[i]){+.+.}, at: lock_crtcs+0x60/0xa4 but task is already holding lock: ffffff80d1339110 (&kms->commit_lock[i]){+.+.}, at: lock_crtcs+0x60/0xa4 other info that might help us debug this: Possible unsafe locking scenario: CPU0 ---- lock(&kms->commit_lock[i]); lock(&kms->commit_lock[i]); *** DEADLOCK *** May be due to missing lock nesting notation 6 locks held by reboot/5213: __arm64_sys_reboot+0x148/0x2a0 device_shutdown+0x10c/0x2c4 drm_atomic_helper_shutdown+0x48/0xfc modeset_lock+0x120/0x24c lock_crtcs+0x60/0xa4 stack backtrace: CPU: 4 PID: 5213 Comm: reboot Not tainted 5.4.91 #1 Hardware name: Google Pompom (rev1) with LTE (DT) Call trace: dump_backtrace+0x0/0x1dc show_stack+0x24/0x30 dump_stack+0xfc/0x1a8 __lock_acquire+0xcd0/0x22b8 lock_acquire+0x1ec/0x240 __mutex_lock_common+0xe0/0xc84 mutex_lock_nested+0x48/0x58 lock_crtcs+0x60/0xa4 msm_atomic_commit_tail+0x348/0x570 commit_tail+0xdc/0x178 drm_atomic_helper_commit+0x160/0x168 drm_atomic_commit+0x68/0x80 This is because lockdep thinks all the locks taken in lock_crtcs() are the same lock, when they actually aren't. That's because we call mutex_init() in msm_kms_init() and that assigns one static key for every lock initialized in this loop. Let's allocate a dynamic number of lock_class_keys and assign them to each lock so that lockdep can figure out an AA deadlock isn't possible here.

Now that we're not racing with GPU setup, also fix races of timestamps against other timestamps. In freedreno CI, we were seeing this path trigger timeouts on setting the GMU bit, producing: [drm:_a6xx_gmu_set_oob] *ERROR* Timeout waiting for GMU OOB set GPU_SET: 0x0 and this triggered especially on the first set of tests right after boot (it's probably easier to lose the race than one might think, given that we start many tests in parallel, and waiting for NFS to page in code probably means that lots of tests hit the same point of screen init at the same time). As of this patch, the message seems to have completely gone away. Signed-off-by:

We were using the same force-poweron bit in the two codepaths, so they could race to have one of them lose GPU power early. freedreno CI was seeing intermittent errors like: [drm:_a6xx_gmu_set_oob] *ERROR* Timeout waiting for GMU OOB set GPU_SET: 0x0 and this issue could have contributed to it.

Before the offending commit in msm_atomic_commit_tail wait_flush was called once per frame, after the commit was submitted. After it wait_flush is also called at the beginning to ensure previous potentially async commits are done. For cmd panels the source of wait_flush is a ping-pong irq notifying a completion. The completion needs to be notified with complete_all so multiple waiting parties (new async committers) can proceed. Signed-off-by:

There is HPD unplug interrupts missed at scenario of an irq_hpd followed by unplug interrupts with around 10 ms in between. Since both AUX_SW_RESET and DP_SW_RESET clear pending HPD interrupts, irq_hpd handler should not issues either aux or sw reset to avoid following unplug interrupt be cleared accidentally.

When configuring the tearcheck, the parameters for the engine were being set mostly as they should've been, but then it wasn't getting configured to get the vsync indication from the TE GPIO input because it was assumed that autorefresh could be enabled: since a previous commit makes sure to disable the autorefresh bit when committing to the cmd engine, it is now safe to just enable the vsync pin input at tearcheck setup time (instead of erroneously never enabling it). Also, set the right sync_cfg_height to enable the DPU auto-generated TE signal in order to avoid stalls in the event that we miss one external TE signal: this will still trigger recovery mechanisms in case the display is really unreachable.

When a command mode display is used, it may be retaining the bootloader configuration which, in most of the cases, enables the autorefresh feature in order to keep the splash up. Since there is no autorefresh management in this driver, wire up the autorefresh ops in the dpu_hw_pingpong and disable the feature when preparing for cmd commit: instead of disabling it when initializing the command mode, this road was chosen as to open future possibility of enabling and managing the autorefresh feature in the driver.

The DSPP_BLK macro was ad-hoc made for SC7180, but this is wrong because not all of the DPU DSPP versions can use the same DSPP block configuration, and not all of them have got the same features. For this reason, add two more params to the DSPP_BLK macro, so that it is possible to specify the feature mask and the sblk config for each DSPP.

Not all DPU interface sub-block versions need the same value for prog_fetch_lines_worst_case: add this to the INTF_BLK macro, so that it becomes possible to vary it for other INTF versions. For example, this is needed to implement support for older SoCs, like MSM8998 and SDM630/660 and most probably will also be needed for future SoCs. Signed-off-by:

On DPUs prior to version 4 the VBIF_XINL_QOS_LVL_REMAP_000 register is at 0x570 offset from vbif base instead of 0x590, due to the VBIF_XINL_QOS_RP_REMAP_000 having less instances (less possible XINs). Signed-off-by:

The upstream API for some reason uses logbase2 instead of just passing the argument as-is, whereas downstream CAF kernel does the latter. Hence, a mistake has been made when porting: 4 is the value that's supposed to be passed, but log2(4) = 2. Changing the value to 16 (= 2^4) fixes the issue. Signed-off-by:

Resetting the VBIF before power collapse is done to avoid getting bogus FIFO entries during the suspend sequence or subsequent resume, but this is doable only on Adreno 510 and Adreno 530, as the other units will tendentially lock up. Especially on Adreno 508, the GPU will show lockups and very bad slownesses after processing the first frame. Avoiding to execute the RBBM SW Reset before suspend will stop the lockup issue from happening on at least Adreno 508/509/512. Signed-off-by:

The "main" if branch where we program the other registers for the Adreno 5xx family of GPUs should not contain the PC_DBG_ECO_CNTL register programming because this has logical similarity differences from all the others. A later commit will show the entire sense of this. Signed-off-by:

AngeloGioacchino Del Regno authored
The PC_DBG_ECO_CNTL register on the Adreno A5xx family gets programmed to some different values on a per-model basis. At least, this is what we intend to do here; Unfortunately, though, this register is being overwritten with a static magic number, right after applying the GPU-specific configuration (including the GPU-specific quirks) and that is effectively nullifying the efforts. Let's remove the redundant and wrong write to the PC_DBG_ECO_CNTL register in order to retain the wanted configuration for the target GPU. Signed-off-by:

A6XX GPUs have support for last level cache(LLC) also known as system cache and need to set the bus attributes to use it. Currently we use a generic adreno iommu address space implementation which are also used by older GPU generations which do not have LLC and might introduce issues accidentally and is not clean in a way that anymore additions of GPUs supporting LLC would have to be guarded under ifdefs. So keep the generic code separate and make the address space creation A6XX specific. We also have a helper to set the llc attributes so that if the newer GPU generations do support them, we can use it instead of open coding domain attribute setting for each GPU. Signed-off-by:

Domain attribute setting for LLCC is guarded by !IS_ERR check which works fine only when CONFIG_QCOM_LLCC=y but when it is disabled, the LLCC apis return NULL and that is not handled by IS_ERR check. Due to this, domain attribute for LLCC will be set even on GPUs which do not support it and cause issues, so correct this by using IS_ERR_OR_NULL checks appropriately. Meanwhile also cleanup comment block and remove unwanted blank line.

On at least MSM8998 it's possible to find Adreno 540.0 and 540.1 but I have never found any 540.2. In any case, the patchids 0-1 for A540 are completely supported by this driver and there is no reason to disallow probing them (as they also share the same firmware names). Besides that, the patchid number is also used in the a5xx_power.c function a540_lm_setup to disable the battery current limiter, which makes faking the Adreno patchid to .2 (which would anyway be sad) useless and even producing breakages.

The process_sysctl_arg() does not check whether val is empty before invoking strlen(val). If the command line parameter () is incorrectly configured and val is empty, oops is triggered. For example: "hung_task_panic=1" is incorrectly written as "hung_task_panic", oops is triggered. The call stack is as follows: Kernel command line: .... hung_task_panic ......
