drm/amd: Fix logic error in sienna_cichlid_update_pcie_parameters()

2023-10-10T20:00:39+00:00

commit 2a1fe39a5be785e962e387146aed34fa9a829f3f upstream. While aligning SMU11 with SMU13 implementation an assumption was made that `dpm_context->dpm_tables.pcie_table` was populated in dpm table initialization like in SMU13 but it isn't. So restore some of the original logic and instead just check for amdgpu_device_pcie_dynamic_switching_supported() to decide whether to hardcode values; erring on the side of performance.

drm/amd: Fix detection of _PR3 on the PCIe root port

2023-10-10T20:00:39+00:00

commit 134b8c5d8674e7cde380f82e9aedfd46dcdd16f7 upstream. On some systems with Navi3x dGPU will attempt to use BACO for runtime PM but fails to resume properly. This is because on these systems the root port goes into D3cold which is incompatible with BACO. This happens because in this case dGPU is connected to a bridge between root port which causes BOCO detection logic to fail. Fix the intent of the logic by looking at root port, not the immediate upstream bridge for _PR3.

drm/amd/display: Adjust the MST resume flow

2023-10-10T20:00:37+00:00

commit ec5fa9fcdeca69edf7dab5ca3b2e0ceb1c08fe9a upstream. [Why] In drm_dp_mst_topology_mgr_resume() today, it will resume the mst branch to be ready handling mst mode and also consecutively do the mst topology probing. Which will cause the dirver have chance to fire hotplug event before restoring the old state. Then Userspace will react to the hotplug event based on a wrong state. [How] Adjust the mst resume flow as: 1. set dpcd to resume mst branch status 2. restore source old state 3. Do mst resume topology probing For drm_dp_mst_topology_mgr_resume(), it's better to adjust it to pull out topology probing work into a 2nd part procedure of the mst resume. Will have a follow up patch in drm.

drm/i915/gt: Fix reservation address in ggtt_reserve_guc_top

2023-10-06T12:57:05+00:00

commit b7599d241778d0b10cdf7a5c755aa7db9b83250c upstream. There is an assertion in ggtt_reserve_guc_top that the global GTT is of size at least GUC_GGTT_TOP, which is not the case on a 32-bit platform; see commit 562d55d991b39ce376c492df2f7890fd6a541ffc ("drm/i915/bdw: Only use 2g GGTT for 32b platforms"). If GEM_BUG_ON is enabled, this triggers a BUG(); if GEM_BUG_ON is disabled, the subsequent reservation fails and the driver fails to initialise the device: i915 0000:00:02.0: [drm:i915_init_ggtt [i915]] Failed to reserve top of GGTT for GuC i915 0000:00:02.0: Device initialization failed (-28) i915 0000:00:02.0: Please file a bug on drm/i915; see https://gitlab.freedesktop.org/drm/intel/-/wikis/How-to-file-i915-bugs for details. i915: probe of 0000:00:02.0 failed with error -28 Make the reservation at the top of the available space, whatever that is, instead of assuming that the top will be GUC_GGTT_TOP.

drm/tests: Fix incorrect argument in drm_test_mm_insert_range

commit 2ba157983974ae1b6aaef7d4953812020d6f1eb5 upstream. While drm_mm test was converted form igt selftest to kunit, unexpected value of "end" argument equal "start" was introduced to one of calls to a function that executes the drm_test_mm_insert_range for specific start/end pair of arguments. As a consequence, DRM_MM_BUG_ON(end <= start) is triggered. Fix it by restoring the original value.

[ Upstream commit 5e7e82254270c8cf8b107451c5de01cee2f135ae ] On some APU systems, there is no atom context and so the atom_context struct is null.
