Add a compatible for the MediaTek MT8370 SoC, with an integrated ARM Mali G57 MC2 GPU (Valhall-JM, dual core), with new platform data for its support in the panfrost driver. It uses the same data as MT8186 for the power management features to describe power supplies, pm_domains and enablement (one regulator, two power domains) but also sets the FORCE_AARCH64_PGTABLE flag in the GPU configuration quirks bitfield to enable AARCH64 4K page table format mode. As MT8186 and MT8370 SoC have different GPU architecture (Mali G52 2EE MC2 for MT8186), making them not compatible, and this mode is only enabled for Mediatek SoC that are Mali G57 based (compatible with mediatek,mali-mt8188 or mediatek,mali-8192), having specific platform data allows to set this flag for MT8370 without modifying MT8186 configuration and behaviour.

So, create a generic power domain array (mediatek_pm_domains) and use it in the mt8183(b), mt8186, mt8188 and mt8192 platform data instead.

2025-06-19drm/bridge: tc358767: convert to devm_drm_bridge_alloc() APILuca Ceresoli
This is the new API for allocating DRM bridges. Converting this driver is a bit complex because the drm_bridge funcs pointer differs based on the bridge mode. So the current code does: * tc_probe() * devm_kzalloc() private struct embedding drm_bridge * call tc_probe_bridge_endpoint() which * parses DT description into struct fields * computes the mode * calls different bridge init functions based on the mode * each sets a different bridge.funcs pointer The new API expects the funcs pointer to be known at alloc time, which does not fit in the current code structure. Solve this by splitting tc_probe_bridge_endpoint() in two functions: * tc_probe_get_mode(), computing the mode without needing the private driver structure * tc_probe_bridge_endpoint(), only initializing the endpoints So now the mode is known before allocation and so is the funcs pointer, while all other operations are still happening after allocation, directly into the private struct data, as they used to. The new code flow is: * tc_probe() * tc_probe_get_mode() * parses DT description * computes and returns the mode * based onf the mode, pick the funcs pointer * devm_drm_bridfge_alloc(..., funcs) * call tc_probe_bridge_endpoint() which * calls different bridge init functions based on the mode * these don't set the funcs pointer, it was done by _alloc This solution is chosen to minimize the changes in the driver logical code flow. The drawback is we now iterate twice over the endpoints during probe.

2025-06-17drm/vmwgfx: Implement dma_fence_ops properlyIan Forbes
vmwgfx's fencing predates dma_fence and as a result dma_fence_ops was never properly implemented, especially with respect to enabling signaling. Because of this dma_fence callbacks don't work properly. This change implements enable_signaling properly so that dma_fence callbacks now work as expected. It also removes vmwgfx's custom implementation of fence callbacks and removes vmwgfx's custom dma_fence_ops::wait function which is no longer necessary now that enable_signaling works.

There was a possible race in vmw_update_seqno. Because of this race it was possible for last_read_seqno to go backwards. Remove this function and replace it with vmw_update_fences which now sets and returns the last_read_seqno while holding the fence lock.

2025-06-17drm/xe/guc: Default log level to non-verboseLucas De Marchi
Currently xe sets the guc log level to a verbose level since it's useful to debug hangs and general development. However the verbose level may already be too much and affect performance. Michal Mrozek did some tests with the L0 compute stack for submission latency with ULLS disabled. Below are the normalized numbers with log level 3 (the current default) as baseline for each test: Test \ Log Level 3 0 1 2 ----------------------------------------------------------- ------ ------ ------ ------ BestWalkerNthCommandListSubmission(CmdListCount=2) 1.00 0.63 0.63 0.96 BestWalkerNthSubmission(KernelCount=2) 1.00 0.62 0.63 0.96 BestWalkerNthSubmissionImmediate(KernelCount=2) 1.00 0.58 0.58 0.85 BestWalkerSubmission 1.00 0.62 0.62 0.96 BestWalkerSubmissionImmediate 1.00 0.63 0.62 0.96 BestWalkerSubmissionImmediateMultiCmdlists(cmdlistCount=2) 1.00 0.58 0.58 0.86 BestWalkerSubmissionImmediateMultiCmdlists(cmdlistCount=4) 1.00 0.70 0.70 0.83 BestWalkerSubmissionImmediateMultiCmdlists(cmdlistCount=8) 1.00 0.53 0.52 0.78 Log level 2 is the first "verbose level" for GuC, where the biggest difference happens.

We already have most for the workarounds for this in place, but the last part is simply not enabling the corresponding interrupt.

2025-06-17drm/i915/dsb: Move the DSB_PMCTRL* reset out of intel_dsb_finish()Ville Syrjälä
When using the flip queue, due to the DMC vs. DSB register corruption problem, we must not issue any register writes from the DSB after unhalting the DMC. Currently we are doing just that by trying to restore DSB_PMCTRL* back to a sane state from intel_dsb_finish(). Since the only place left that pokes at DSB_PMCTRL* is intel_dsb_chain() we can just do DSB_PMCTRL_2/DSB_FORCE_DEWAKE reset in the same place. The DSB_PMCTRL reset is trickier since we'd have to do it from the chained DSB itself. But based on my earlier testing DSB_PMCTRL/DSB_ENABLE_DEWAKE doesn't actually do anything if the DSB isn't actually enabled, so we can omit the reset to keep things a bit simpler. We do need to reset DSB_PMCTRL/DSB_ENABLE_DEWAKE before tarting the DSB however, in case it was left enabled from a previous use.
