2024-06-24drm/i915: Update plane alignment requirements for TGL+Ville Syrjälä
Currently we still use the SKL+ PLANE_SURF alignment even for TGL+ even though the hardware no longer needs it. Introduce a separate tgl_plane_min_alignment() and update it to more accurately reflect the hardware requirements. v2: Don't screw up DPT+semiplanar 2MiB alignment Reviewed-by: Imre Deak <imre.deak@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240612204712.31404-9-ville.syrjala@linux.intel.com

2024-06-24tty: serial: 8250: Fix port count mismatch with the deviceCrescent Hsieh
Normally, the number of ports is indicated by the third digit of the device ID on Moxa PCI serial boards. For example, `0x1121` indicates a device with 2 ports. However, `CP116E_A_A` and `CP116E_A_B` are exceptions; they have 8 ports, but the third digit of the device ID is `6`. This patch introduces a function to retrieve the number of ports on Moxa PCI serial boards, addressing the issue described above.

2024-06-24drm/i915: Introduce fb->min_alignmentVille Syrjälä
Different planes could have different alignment requirements even for the same format/modifier. Collect the alignment requirements across all planes capable of scanning out the fb such that the alignment is satisfactory to all those planes. So far this was sort of handled by making sure intel_surf_alignment() declares the superset of all planes' alignment requirements, but maintaining that manually is annoying. So we're going to move towards each plane declaring only its own requirements, and thus we need code to generate the superset. v2: Drop the borked per-plane vma optimization (Imre) Assert that the plane's declared alignment is POT (Imre) Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240612204712.31404-5-ville.syrjala@linux.intel.com Reviewed-by: Imre Deak <imre.deak@intel.com>

Different hardware generations have different scanout alignment requirements. Introduce a new vfunc that will allow us to make that distinction without horrible if-ladders. For now we directly plug in the existing intel_surf_alignment() and intel_cursor_alignment() functions.

2024-06-24staging: vc04_services: vchiq_arm: Fix initialisation checkKieran Bingham
The vchiq_state used to be obtained through an accessor which would validate that the VCHIQ had been initialised correctly with the remote, or return a null state. In commit 42a2f6664e18 ("staging: vc04_services: Move global g_state to vchiq_state") the global state was moved to the vchiq_mgnt structures stored as a vchiq instance specific context. This conversion removed the helpers and instead replaced users of this helper with the assumption that the state is always available and the remote connected. The conversion does ensure that the state is always available, so some remaining state null pointer checks that remain are unnecessary, but the assumption that the remote is present and initialised is incorrect. Fix this broken assumption by re-introducing the logic that was lost during the conversion.

2024-06-24ASoC: mediatek: mt8195: Add platform entry for ETDM1_OUT_BE dai linkChen-Yu Tsai
Commit e70b8dd26711 ("ASoC: mediatek: mt8195: Remove afe-dai component and rework codec link") removed the codec entry for the ETDM1_OUT_BE dai link entirely instead of replacing it with COMP_EMPTY(). This worked by accident as the remaining COMP_EMPTY() platform entry became the codec entry, and the platform entry became completely empty, effectively the same as COMP_DUMMY() since snd_soc_fill_dummy_dai() doesn't do anything for platform entries. This causes a KASAN out-of-bounds warning in mtk_soundcard_common_probe() in sound/soc/mediatek/common/mtk-soundcard-driver.c: for_each_card_prelinks(card, i, dai_link) { if (adsp_node && !strncmp(dai_link->name, "AFE_SOF", strlen("AFE_SOF"))) dai_link->platforms->of_node = adsp_node; else if (!dai_link->platforms->name && !dai_link->platforms->of_node) dai_link->platforms->of_node = platform_node; } where the code expects the platforms array to have space for at least one entry.

2024-06-24xdp: Remove WARN() from __xdp_reg_mem_model()Daniil Dulov
syzkaller reports a warning in __xdp_reg_mem_model(). The warning occurs only if __mem_id_init_hash_table() returns an error. It returns the error in two cases: 1. memory allocation fails; 2. rhashtable_init() fails when some fields of rhashtable_params struct are not initialized properly. The second case cannot happen since there is a static const rhashtable_params struct with valid fields. So, warning is only triggered when there is a problem with memory allocation. Thus, there is no sense in using WARN() to handle this error and it can be safely removed.

2024-06-24bpf: Fix may_goto with negative offset.Alexei Starovoitov
Zac's syzbot crafted a bpf prog that exposed two bugs in may_goto. The 1st bug is the way may_goto is patched. When offset is negative it should be patched differently. The 2nd bug is in the verifier: when current state may_goto_depth is equal to visited state may_goto_depth it means there is an actual infinite loop. It's not correct to prune exploration of the program at this point. Note, that this check doesn't limit the program to only one may_goto insn, since 2nd and any further may_goto will increment may_goto_depth only in the queued state pushed for future exploration. The current state will have may_goto_depth == 0 regardless of number of may_goto insns and the verifier has to explore the program until bpf_exit.

When CONFIG_FONTS ("Select compiled-in fonts") is not enabled, the user should not be asked about any fonts. However, when CONFIG_DRM_PANIC is enabled, the user is still asked about the Sparc console 12x22 and Terminus 16x32 fonts. Fix this by moving the "|| DRM_PANIC" to where it belongs.

No implementations of drm_plane_helper_funcs.get_scanout_buffer() fill in the optional drm_scanout_buffer.set_pixel() member.

In the past, there were similar failures reported by CI from other IGT tests, observed on other platforms. Before commit 63baf4f3d587 ("drm/i915/gt: Only wait for GPU activity before unbinding a GGTT fence"), i915_vma_revoke_fence() was waiting for idleness of vma->active via fence_update(). That commit introduced vma->fence->active in order for the fence_update() to be able to wait selectively on that one instead of vma->active since only idleness of fence registers was needed. But then, another commit 0d86ee35097a ("drm/i915/gt: Make fence revocation unequivocal") replaced the call to fence_update() in i915_vma_revoke_fence() with only fence_write(), and also added that GEM_BUG_ON(!i915_active_is_idle(&fence->active)) in front. No justification was provided on why we might then expect idleness of vma->fence->active without first waiting on it. The issue can be potentially caused by a race among revocation of fence registers on one side and sequential execution of signal callbacks invoked on completion of a request that was using them on the other, still processed in parallel to revocation of those fence registers. Fix it by waiting for idleness of vma->fence->active in i915_vma_revoke_fence().
