[PATCH v2 0/5] drm/solomon: Add SSD130x OLED displays SPI support
by Javier Martinez Canillas 12 Apr '22

12 Apr '22

Hello, This series adds a ssd130x-spi driver that provides a 4-wire SPI transport support for SSD130x OLED controllers that can be accessed through a SPI. The driver is quite similar to existing ssd130x-i2c driver that is used by I2C controllers, but there is a difference in the protocol used by SSD130x depending on the transport used. The details are in patch #4 description. Patch #1 just makes the current ssd130x-i2c compatible strings in the DT binding to be deprecated, and add new ones that don't have an "fb-i2c". Patch #2 extends the DT binding with the properties needed to support SPI. Patch #3 adds the new compatible strings to the OF device ID table in the ssd130x-i2c DRM driver and deprecate the old ones. Patch #4 moves the device info for the different SSD130x variants from the ssd130x-i2c transport driver to the ssd130x core driver. Finally patch #5 adds the ssd130x-spi DRM driver for the OLED controllers that come with a 4-wire SPI interface, instead of an I2C interface. This is a v2 that addresses the issues pointed out in v1. Best regards, Javier Changes in v2: - Drop the -i2c suffixes from the compatible strings too (Geert Uytterhoeven). - Don't add compatible strings with an "-spi" suffix (Geert Uytterhoeven). - Drop ssd13x_variant_to_info() and just use the array index (Neil Armstrong). - Add Mark Brown's Acked-by tag to all patches.

[PATCHv3] drm/amdgpu: disable ASPM on Intel Alder Lake based systems
by Richard Gong 12 Apr '22

12 Apr '22

Active State Power Management (ASPM) feature is enabled since kernel 5.14. There are some AMD GFX cards (such as WX3200 and RX640) that won't work with ASPM-enabled Intel Alder Lake based systems. Using these GFX cards as video/display output, Intel Alder Lake based systems will hang during suspend/resume. The issue was initially reported on one system (Dell Precision 3660 with BIOS version 0.14.81), but was later confirmed to affect at least 4 Alder Lake based systems. Add extra check to disable ASPM on Intel Alder Lake based systems.

AMD Display Core (DC) patches (was: [PATCH 13/16] drm/amd/display: Revert FEC check in validation)

[Cc: +dri-devel(a)lists.freedesktop.org, +Daniel Vetter, +Alexander Deucher, +Greg KH] Dear Alex, I am a little confused and upset about how Display Core patches are handled in the Linux kernel.

I guess, because these indicators and meta data are missing. > why and how: > causes failure on install on certain machines Why are such kind of commit messages accepted? What does “failure on install” even mean? Why can’t the machine configuration be documented so it can be reproduced, when necessary. No less confusing, the date you posted it on amd-gfx is from March 25th, 2022, but the author date of the commit in agd5f/amd-staging-drm-next is `Fri Mar 18 11:12:36 2022 -0400`.

Seeing how many people are in the Cc list, I would have hoped, that somebody noticed and commented. The current state also makes it really hard for non-AMD employees to get the necessary information to do proper reviews as the needed documentation and information is non-public. So good/excellent commit messages are a must. I think to remember, you replied to me once, that Display Core patches are shared also with the Microsoft Windows driver, restricting the workflow options. But I think the issues I mentioned are unrelated. I know graphics hardware is very complex, but if quality of the commits and review would be improved, hopefully it saves time for everyone in the end, as less bugs are introduced. Could AMD team please address these issues as soon as possible? Kind regards, Paul

If we hit the sync case, like when skipping clearing for kernel internal objects, or when falling back to cpu clearing, like in i915, we end up trying to add a NULL fence, but with some recent changes in this area this now just results in NULL deref in dma_resv_add_fence: <1>[ 5.466383] BUG: kernel NULL pointer dereference, address: 0000000000000008 <1>[ 5.466384] #PF: supervisor read access in kernel mode <1>[ 5.466385] #PF: error_code(0x0000) - not-present page <6>[ 5.466386] PGD 0 P4D 0 <4>[ 5.466387] Oops: 0000 [#1] PREEMPT SMP NOPTI <4>[ 5.466389] CPU: 5 PID: 267 Comm: modprobe Not tainted 5.18.0-rc2-CI-CI_DRM_11481+ #1 <4>[ 5.466391] RIP: 0010:dma_resv_add_fence+0x63/0x260 <4>[ 5.466395] Code: 38 85 c0 0f 84 df 01 00 00 0f 88 e8 01 00 00 83 c0 01 0f 88 df 01 00 00 8b 05 35 89 10 01 49 8d 5e 68 85 c0 0f 85 45 01 00 00 <48> 8b 45 08 48 3d c0 a5 0a 82 0f 84 5c 01 00 00 48 3d 60 a5 0a 82 <4>[ 5.466396] RSP: 0018:ffffc90000e974f8 EFLAGS: 00010202 <4>[ 5.466397] RAX: 0000000000000001 RBX: ffff888123e88b28 RCX: 00000000ffffffff <4>[ 5.466398] RDX: 0000000000000001 RSI: ffffffff822e4f50 RDI: ffffffff8233f087 <4>[ 5.466399] RBP: 0000000000000000 R08: ffff8881313dbc80 R09: 0000000000000001 <4>[ 5.466399] R10: 0000000000000001 R11: 00000000da354294 R12: 0000000000000000 <4>[ 5.466400] R13: ffff88810927dc58 R14: ffff888123e88ac0 R15: ffff88810a88d600 <4>[ 5.466401] FS: 00007f5fa1193540(0000) GS:ffff88845d880000(0000) knlGS:0000000000000000 <4>[ 5.466402] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 <4>[ 5.466402] CR2: 0000000000000008 CR3: 0000000106dd6003 CR4: 00000000003706e0 <4>[ 5.466403] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 <4>[ 5.466404] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 <4>[ 5.466404] Call Trace: <4>[ 5.466405] <TASK> <4>[ 5.466406] ttm_bo_move_accel_cleanup+0x62/0x270 [ttm] <4>[ 5.466411] ? i915_rsgt_from_buddy_resource+0x185/0x1e0 [i915] <4>[ 5.466529] i915_ttm_move+0xfd/0x430 [i915] <4>[ 5.466833] ? dma_resv_reserve_fences+0x4e/0x320 <4>[ 5.466836] ? ttm_bo_add_move_fence.constprop.20+0xf7/0x140 [ttm] <4>[ 5.466841] ttm_bo_handle_move_mem+0xa1/0x140 [ttm] <4>[ 5.466845] ttm_bo_validate+0xee/0x160 [ttm] <4>[ 5.466849] __i915_ttm_get_pages+0x4f/0x210 [i915] <4>[ 5.466976] i915_ttm_get_pages+0xad/0x140 [i915] <4>[ 5.467094] ____i915_gem_object_get_pages+0x32/0xf0 [i915] <4>[ 5.467210] __i915_gem_object_get_pages+0x89/0xa0 [i915] <4>[ 5.467323] i915_vma_get_pages+0x114/0x1d0 [i915] <4>[ 5.467446] i915_vma_pin_ww+0xd3/0xa90 [i915] <4>[ 5.467570] i915_vma_pin.constprop.10+0x119/0x1b0 [i915] <4>[ 5.467700] ? __mutex_unlock_slowpath+0x3e/0x2b0 <4>[ 5.467704] intel_alloc_initial_plane_obj.isra.6+0x1a9/0x390 [i915] <4>[ 5.467833] intel_crtc_initial_plane_config+0x83/0x340 [i915] In the ttm_bo_move_sync_cleanup() case it seems we only really care about calling ttm_bo_wait_free_node(), so let's instead just call that directly.

[PATCH 00/10] drm/sun4i: Allwinner D1 Display Engine 2.0 Support
by Samuel Holland 12 Apr '22

12 Apr '22

This series adds binding and driver support for Display Engine 2.0 variant found in the Allwinner D1. So far it has only been tested with HDMI. I will be sending the HDMI support series separately, because the hardware comes with a brand new custom HDMI PHY, which requires some refactoring to support cleanly. Samuel Holland (10): dt-bindings: display: Separate clock item lists by compatible dt-bindings: display: Add D1 display engine compatibles drm/sun4i: Remove obsolete references to PHYS_OFFSET drm/sun4i: Allow building the driver on RISC-V drm/sun4i: csc: Add support for the new MMIO layout drm/sun4i: Allow VI layers to be primary planes drm/sun4i: Add support for D1 mixers drm/sun4i: Add support for D1 TCON TOP drm/sun4i: Add support for D1 TCONs drm/sun4i: Add compatible for D1 display engine .../allwinner,sun4i-a10-display-engine.yaml | 1 + .../display/allwinner,sun4i-a10-tcon.yaml | 2 + .../allwinner,sun8i-a83t-de2-mixer.yaml | 2 + .../display/allwinner,sun8i-r40-tcon-top.yaml | 145 ++++++++++++------ drivers/gpu/drm/sun4i/Kconfig | 2 +- drivers/gpu/drm/sun4i/sun4i_drv.c | 1 + drivers/gpu/drm/sun4i/sun4i_frontend.c | 3 - drivers/gpu/drm/sun4i/sun4i_tcon.c | 8 + drivers/gpu/drm/sun4i/sun8i_csc.c | 3 +- drivers/gpu/drm/sun4i/sun8i_csc.h | 1 + drivers/gpu/drm/sun4i/sun8i_mixer.c | 26 ++++ drivers/gpu/drm/sun4i/sun8i_mixer.h | 6 +- drivers/gpu/drm/sun4i/sun8i_tcon_top.c | 15 +- drivers/gpu/drm/sun4i/sun8i_vi_layer.c | 36 ++++- 14 files changed, 196 insertions(+), 55 deletions(-) -- 2.35.1
