[PATCH] drm/i915/gt: Handle errors for i915_gem_object_trylock
by Jiasheng Jiang 03 Mar '22

As the potential failure of the i915_gem_object_trylock(), it should be better to check it and return error if fails.

[PATCH 1/5] drm/i915/vlv_dsi: Add DMI quirk for wrong panel modeline in BIOS on Asus TF103C (v2)
by Hans de Goede 03 Mar '22

03 Mar '22

Vtotal is wrong in the BIOS supplied modeline for the DSI panel on the Asus TF103C leading to the last line of the display being shown as the first line. Original: "1280x800": 60 67700 1280 1312 1328 1376 800 808 812 820 0x8 0xa Fixed: "1280x800": 60 67700 1280 1312 1328 1376 800 808 812 816 0x8 0xa The factory installed Android has a hardcoded modeline in its kernel, causing it to not suffer from this BIOS bug; and the Android boot-splash which uses the EFI FB which does have this bug has the last line all black causing the bug to not be visible. This commit introduces a generic DMI based quirk mechanism to vlv_dsi for doing various fixups, and uses this to correct the modeline. v2: - s/mode_fixup/dmi_quirk/ to make the new DMI quirk mechanism more generic - Add a comment with the old and new modelines to the patch and commit msg Reviewed-by: Javier Martinez Canillas <javierm(a)redhat.com> Signed-off-by: Hans de Goede <hdegoede(a)redhat.com> --- drivers/gpu/drm/i915/display/vlv_dsi.c | 40 ++++++++++++++++++++++++++ 1 file changed, 40 insertions(+) diff --git a/drivers/gpu/drm/i915/display/vlv_dsi.c b/drivers/gpu/drm/i915/display/vlv_dsi.c index 06ef822c27bd..831ca6401c51 100644 --- a/drivers/gpu/drm/i915/display/vlv_dsi.c +++ b/drivers/gpu/drm/i915/display/vlv_dsi.c @@ -23,6 +23,7 @@ * Author: Jani Nikula <jani.nikula(a)intel.com> */ +#include <linux/dmi.h> #include <linux/slab.h> #include <drm/drm_atomic_helper.h> @@ -1831,6 +1832,36 @@ static void vlv_dphy_param_init(struct intel_dsi *intel_dsi) intel_dsi_log_params(intel_dsi); } +typedef void (*vlv_dsi_dmi_quirk_func)(struct intel_dsi *intel_dsi, + struct drm_display_mode *fixed_mode); + +/* + * Vtotal is wrong on the Asus TF103C leading to the last line of the display + * being shown as the first line.

[PATCH v2 0/3] Improve anti-pre-emption w/a for compute workloads
by John.C.Harrison＠Intel.com 03 Mar '22

03 Mar '22

From: John Harrison <John.C.Harrison(a)Intel.com> Compute workloads are inherently not pre-emptible on current hardware. Thus the pre-emption timeout was disabled as a workaround to prevent unwanted resets. Instead, the hang detection was left to the heartbeat and its (longer) timeout. This is undesirable with GuC submission as the heartbeat is a full GT reset rather than a per engine reset and so is much more destructive. Instead, just bump the pre-emption timeout to a big value. Also, update the heartbeat to allow such a long pre-emption delay in the final heartbeat period. v2: Add clamping helpers.

[PATCH 00/15] drm/i915: Enable DG2
by Ramalingam C 03 Mar '22

03 Mar '22

Enabling the Dg2 on drm/i915. This series adds support for 64k pagesize and documents the uapi impacts. And also adds basic flat-ccs enabling patches to support the local memory initialization and object creation. Kdoc is added to document the Flat-ccs support. Flat-ccs modifiers will be enabled in upcoming patches. Note: This is subset of https://patchwork.freedesktop.org/series/95686/ The remaining patches of the series will be pursued in subsequent series. And few patches are reviewed at and pulled from many series like https://patchwork.freedesktop.org/series/99119/ https://patchwork.freedesktop.org/series/100373/ https://patchwork.freedesktop.org/series/97544/ Abdiel Janulgue (1): drm/i915/lmem: Enable lmem for platforms with Flat CCS Ayaz A Siddiqui (1): drm/i915/gt: Clear compress metadata for Xe_HP platforms CQ Tang (1): drm/i915/xehpsdv: Add has_flat_ccs to device info John Harrison (1): drm/i915/dg2: Define GuC firmware version for DG2 Jouni Högander (1): drm/i915: Fix for PHY_MISC_TC1 offset Matt Roper (2): drm/i915/dg2: Drop 38.4 MHz MPLLB tables drm/i915/dg2: Enable 5th port Matthew Auld (6): drm/i915: enforce min GTT alignment for discrete cards drm/i915: support 64K GTT pages for discrete cards drm/i915/gtt: allow overriding the pt alignment drm/i915/gtt: add xehpsdv_ppgtt_insert_entry drm/i915/migrate: add acceleration support for DG2 drm/i915/uapi: document behaviour for DG2 64K support Ramalingam C (1): drm/i915: add needs_compact_pt flag Robert Beckett (1): drm/i915: add gtt misalignment test drivers/gpu/drm/i915/display/intel_display.c | 1 + drivers/gpu/drm/i915/display/intel_gmbus.c | 16 +- drivers/gpu/drm/i915/display/intel_snps_phy.c | 210 +---------- .../gpu/drm/i915/gem/selftests/huge_pages.c | 60 ++++ .../i915/gem/selftests/i915_gem_client_blt.c | 21 +- drivers/gpu/drm/i915/gt/gen8_ppgtt.c | 158 +++++++- drivers/gpu/drm/i915/gt/intel_gpu_commands.h | 15 + drivers/gpu/drm/i915/gt/intel_gt.c | 19 + drivers/gpu/drm/i915/gt/intel_gt.h | 1 + drivers/gpu/drm/i915/gt/intel_gt_regs.h | 3 + drivers/gpu/drm/i915/gt/intel_gtt.c | 12 + drivers/gpu/drm/i915/gt/intel_gtt.h | 35 +- drivers/gpu/drm/i915/gt/intel_migrate.c | 337 ++++++++++++++++-- drivers/gpu/drm/i915/gt/intel_ppgtt.c | 17 +- drivers/gpu/drm/i915/gt/intel_region_lmem.c | 26 +- drivers/gpu/drm/i915/gt/uc/intel_uc_fw.c | 1 + drivers/gpu/drm/i915/i915_drv.h | 17 +- drivers/gpu/drm/i915/i915_irq.c | 5 +- drivers/gpu/drm/i915/i915_pci.c | 3 + drivers/gpu/drm/i915/i915_reg.h | 7 +- drivers/gpu/drm/i915/i915_vma.c | 9 + drivers/gpu/drm/i915/intel_device_info.h | 2 + drivers/gpu/drm/i915/selftests/i915_gem_gtt.c | 222 ++++++++++-- include/uapi/drm/i915_drm.h | 45 ++- 24 files changed, 934 insertions(+), 308 deletions(-) -- 2.20.1
