2025-09-08drm/msm/a6xx: Enable IFPC on A750 GPUAkhil P Oommen
A750 GPU has similar IFPC related configurations like X1-85. Add the IFPC QUIRK to enable IFPC feature. Signed-off-by: Akhil P Oommen <akhilpo@oss.qualcomm.com> Patchwork: https://patchwork.freedesktop.org/patch/673386/ Signed-off-by: Rob Clark <robin.clark@oss.qualcomm.com>

2025-09-08drm/msm/a6xx: Make crashstate capture IFPC safeAkhil P Oommen
Now with IFPC, GX domain can collapse as soon as GPU becomes IDLE. So add gx_is_on check before accessing any GX registers during crashstate capture and recovery.

2025-09-08drm/msm/adreno: Disable IFPC when sysprof is activeAkhil P Oommen
Moving to IFPC state clears the 'Perfcounter Select' register setup by the userspace. So, lets block the IFPC when sysprof is active by using the perfcounter oob signal to the GMU.

2025-09-08drm/msm/a6xx: Fix hangcheck for IFPCAkhil P Oommen
From the hangcheck handler, KMD checks a few registers in GX domain to see if the GPU made any progress. But it cannot access those registers when IFPC is enabled. Since HW based hang detection is pretty decent, lets rely on it instead of these registers when IFPC is enabled.

2025-09-08drm/msm/a6xx: Poll AHB fence status in GPU IRQ handlerAkhil P Oommen
Even though the GX power domain is kept ON when there is a pending GPU interrupt, there is a small window of potential race with GMU where it may move the AHB fence to 'Drop' mode. Once the GMU sees the pending IRQ, it will move back the fence state to ALLOW mode. Close this race window by polling for AHB fence to ensure that it is in 'Allow' mode.

2025-09-08drm/msm/a6xx: Switch to GMU AO counterAkhil P Oommen
CP_ALWAYS_ON counter falls under GX domain which is collapsed during IFPC. So switch to GMU_ALWAYS_ON counter for any CPU reads since it is not impacted by IFPC. Both counters are clocked by same xo clock source.

2025-09-08drm/msm/a6xx: Set Keep-alive votes to block IFPCAkhil P Oommen
Set Keepalive votes at appropriate places to block IFPC power collapse until we access all the required registers. This is required during gpu IRQ handling and also during preemption.

2025-09-08drm/msm/adreno: Add fenced regwrite supportAkhil P Oommen
There are some special registers which are accessible even when GX power domain is collapsed during an IFPC sleep. Accessing these registers wakes up GPU from power collapse and allow programming these registers without additional handshake with GMU. This patch adds support for this special register write sequence.

2025-09-08drm/msm: Add an ftrace for gpu register accessAkhil P Oommen
With IFPC, there is a probability of accessing a GX domain register when it is collapsed, which leads to gmu fence errors. To debug this, we need to trace every gpu register accesses and identify the one just before a gmu fence error. So, add an ftrace to track all gpu register accesses.

2025-09-08drm/msm: a6xx: Refactor a6xx_sptprac_enable()Akhil P Oommen
A minor refactor to combine the subroutines for legacy a6xx GMUs under a single check. This helps to avoid an unnecessary check and return early from the subroutine for majority of a6xx gpus. Also, document an intermediate unknown low power state which is not exposed by the GMU firmware.

2025-09-08drm/msm/a6xx: Fix PDC sleep sequenceAkhil P Oommen
Since the PDC resides out of the GPU subsystem and cannot be reset in case it enters bad state, utmost care must be taken to trigger the PDC wake/sleep routines in the correct order. The PDC wake sequence can be exercised only after a PDC sleep sequence. Additionally, GMU firmware should initialize a few registers before the KMD can trigger a PDC sleep sequence. So PDC sleep can't be done if the GMU firmware has not initialized. Track these dependencies using a new status variable and trigger PDC sleep/wake sequences appropriately.
