[PATCH 1/8] drm/i915/migrate: don't check the scratch page
by Matthew Auld 02 Dec '21

02 Dec '21

The scratch page might not be allocated in LMEM(like on DG2), so instead of using that as the deciding factor for where the paging structures live, let's just query the pt before mapping it.

[PATCH] drm/radeon/radeon_kms: Fix a NULL pointer dereference in radeon_driver_open_kms()
by Zhou Qingyang 02 Dec '21

02 Dec '21

In radeon_driver_open_kms(), radeon_vm_bo_add() is assigned to vm->ib_bo_va and passes and used in radeon_vm_bo_set_addr(). In radeon_vm_bo_set_addr(), there is a dereference of vm->ib_bo_va, which could lead to a NULL pointer dereference on failure of radeon_vm_bo_add(). Fix this bug by adding a check of vm->ib_bo_va. This bug was found by a static analyzer. The analysis employs differential checking to identify inconsistent security operations (e.g., checks or kfrees) between two code paths and confirms that the inconsistent operations are not recovered in the current function or the callers, so they constitute bugs. Note that, as a bug found by static analysis, it can be a false positive or hard to trigger. Multiple researchers have cross-reviewed the bug. Builds with CONFIG_DRM_RADEON=m show no new warnings, and our static analyzer no longer warns about this code.

[PATCH] fix a NULL pointer dereference in amdgpu_connector_lcd_native_mode()
by Zhou Qingyang 02 Dec '21

02 Dec '21

In amdgpu_connector_lcd_native_mode(), the return value of drm_mode_duplicate() is assigned to mode, and there is a dereference of it in amdgpu_connector_lcd_native_mode(), which will lead to a NULL pointer dereference on failure of drm_mode_duplicate().

Finally, HDMI audio is enabled in device-trees.

This is a note for Mark Brown. I also based this series on top of power management series [2]. I.e. [2] should be applied first, otherwise "Add S/PDIF node to Tegra20 device-tree" patch should have merge conflict. This is a note for Thierry.

[PATCH v3 0/2] R-Car DU: Add DSI encoder driver for V3U
by Laurent Pinchart 02 Dec '21

02 Dec '21

Hello, This patch series adds a driver for the DSI encoder found in the R-Car V3U SoC, which is the first SoC in the family that supports DSI. The driver is based on an implementation from the BSP written by Luu Hoai, with lots of further rework. If anyone is interested in the history, a broken down v1 is available from [1]. The driver has been successfully tested on the Falcon board, which connects an SN65DSI86 to the output of the DSI encoder. Further patches are needed for the ti-sn65dsi86 driver to enable usage in plain DP (non-eDP) mode, as the Falcon board has a mini-DP connector wired to the output of the SN65DSI86. This is work in progress (see [2]).

linux-next: manual merge of the drm-intel-gt tree with the drm-intel tree

Hi all, Today's linux-next merge of the drm-intel-gt tree got a conflict in: drivers/gpu/drm/i915/display/intel_fbc.c between commit: d06188234427 ("drm/i915/fbc: s/dev_priv/i915/") from the drm-intel tree and commit: cca084692394 ("drm/i915: Use per device iommu check") from the drm-intel-gt tree. I fixed it up (see below) and can carry the fix as necessary. This is now fixed as far as linux-next is concerned, but any non trivial conflicts should be mentioned to your upstream maintainer when your tree is submitted for merging. You may also want to consider cooperating with the maintainer of the conflicting tree to minimise any particularly complex conflicts. -- Cheers, Stephen Rothwell diff --cc drivers/gpu/drm/i915/display/intel_fbc.c index d0c34bc3af6c,c40444206425..000000000000 --- a/drivers/gpu/drm/i915/display/intel_fbc.c +++ b/drivers/gpu/drm/i915/display/intel_fbc.c @@@ -1674,12 -1536,12 +1674,12 @@@ static int intel_sanitize_fbc_option(st return 0; } -static bool need_fbc_vtd_wa(struct drm_i915_private *dev_priv) +static bool need_fbc_vtd_wa(struct drm_i915_private *i915) { /* WaFbcTurnOffFbcWhenHyperVisorIsUsed:skl,bxt */ - if (intel_vtd_active() && - if (intel_vtd_active(dev_priv) && - (IS_SKYLAKE(dev_priv) || IS_BROXTON(dev_priv))) { - drm_info(&dev_priv->drm, ++ if (intel_vtd_active(i915) && + (IS_SKYLAKE(i915) || IS_BROXTON(i915))) { + drm_info(&i915->drm, "Disabling framebuffer compression (FBC) to prevent screen flicker with VT-d enabled\n"); return true; }
