https://bugzilla.kernel.org/show_bug.cgi?id=204849 Bug ID: 204849 Summary: amdgpu (RX560X) traceboot in dmesg boot output, system instability Product: Drivers Version: 2.5 Kernel Version: 5.3-rc8 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri(… [View More]a)kernel-bugs.osdl.org Reporter: justin(a)postgresql.org Regression: No Trying to sort out a system stability problem with my new laptop (Acer Nitro 5, model AN515-42-R3EE) with Ryzen 2700U and RX560X. dmesg output shows traceback for amdgpu with kernel 5.3-rc8, all prior kernels I've tested (various 4.x, and 5.3-rc7) also have various tracebacks shown in amdgpu. Here's the 5.3-rc8 kernel one, note there are several that show up at the same time in the dmesg output, all amdgpu related: *********************************************************************** [ 5.662316] ------------[ cut here ]------------ [ 5.662430] WARNING: CPU: 2 PID: 403 at drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_link.c:1882 write_i2c_default_retimer_setting.cold+0x45 /0xab [amdgpu] [ 5.662431] Modules linked in: hid_generic usbhid amdgpu(+) crct10dif_pclmul crc32_pclmul crc32c_intel rtsx_pci_sdmmc ghash_clmulni_intel mmc_co re amd_iommu_v2 gpu_sched i2c_algo_bit aesni_intel drm_kms_helper aes_x86_64 xhci_pci crypto_simd syscopyarea sysfillrect xhci_hcd sysimgblt fb_sys _fops ttm cryptd glue_helper drm usbcore serio_raw rtsx_pci video wmi pinctrl_amd i2c_hid button dm_mirror dm_region_hash dm_log sg dm_multipath dm _mod scsi_dh_rdac scsi_dh_emc scsi_dh_alua efivarfs [ 5.662449] CPU: 2 PID: 403 Comm: systemd-udevd Not tainted 5.3.0-rc8-2.gd6f0b71-default #1 openSUSE Tumbleweed (unreleased) [ 5.662450] Hardware name: Acer Nitro AN515-42/Freed_RRS, BIOS V1.13 02/11/2019 [ 5.662530] RIP: 0010:write_i2c_default_retimer_setting.cold+0x45/0xab [amdgpu] [ 5.662532] Code: 76 2c b5 d8 0f 0b e9 ab 14 fd ff 48 c7 c7 c0 7d c7 c0 e8 63 2c b5 d8 0f 0b e9 ea 13 fd ff 48 c7 c7 c0 7d c7 c0 e8 50 2c b5 d8 <0f> 0b e9 83 13 fd ff 48 c7 c7 c0 7d c7 c0 e8 3d 2c b5 d8 0f 0b e9 [ 5.662533] RSP: 0018:ffffaccd804b7248 EFLAGS: 00010246 [ 5.662534] RAX: 0000000000000024 RBX: 0000000000000000 RCX: 0000000000000000 [ 5.662534] RDX: 0000000000000000 RSI: ffff9eb08ec99a18 RDI: ffff9eb08ec99a18 [ 5.662535] RBP: ffff9eb077d401b8 R08: ffff9eb08ec99a18 R09: ffff9eb08f219c40 [ 5.662535] R10: 0000000000000406 R11: 00000000000ea8ac R12: 0000000000000000 [ 5.662536] R13: 0000000000000000 R14: ffff9eb077c00000 R15: ffff9eb077ce3800 [ 5.662537] FS: 00007f7734d34d40(0000) GS:ffff9eb08ec80000(0000) knlGS:0000000000000000 [ 5.662537] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 5.662538] CR2: 00007f772e838a70 CR3: 000000023ebe2000 CR4: 00000000003406e0 [ 5.662538] Call Trace: [ 5.662619] core_link_enable_stream+0x861/0x870 [amdgpu] [ 5.662696] ?

[RFC PATCH 0/4] Add a RPMsg driver to support AI Processing Unit (APU)
by Alexandre Bailon 20 Jul '21

20 Jul '21

This adds a RPMsg driver that implements communication between the CPU and an APU. This uses VirtIO buffer to exchange messages but for sharing data, this uses a dmabuf, mapped to be shared between CPU (userspace) and APU. The driver is relatively generic, and should work with any SoC implementing hardware accelerator for AI if they use support remoteproc and VirtIO. For the people interested by the firmware or userspace library, the sources are available here: https://github.com/BayLibre/open-… [View More]

[PATCH] drm/vc4: dsi: Only register our component once a DSI device is attached
by Maxime Ripard 05 Jul '21

05 Jul '21

If the DSI driver is the last to probe, component_add will try to run all the bind callbacks straight away and return the error code. However, since we depend on a power domain, we're pretty much guaranteed to be in that case on the BCM2711, and are just lucky on the previous SoCs since the v3d also depends on that power domain and is further in the probe order. In that case, the DSI host will not stick around in the system: the DSI bind callback will be executed, will not find any DSI device … [View More]attached and will return EPROBE_DEFER, and we will then remove the DSI host and ask to be probed later on. But since that host doesn't stick around, DSI devices like the RaspberryPi touchscreen whose probe is not linked to the DSI host (unlike the usual DSI devices that will be probed through the call to mipi_dsi_host_register) cannot attach to the DSI host, and we thus end up in a situation where the DSI host cannot probe because the panel hasn't probed yet, and the panel cannot probe because the DSI host hasn't yet. In order to break this cycle, let's wait until there's a DSI device that attaches to the DSI host to register the component and allow to progress further.

[PATCH] drm/rockchip: cdn-dp: fix sign extension on an int multiply for a u64 result

From: Colin Ian King <colin.king(a)canonical.com> The variable bit_per_pix is a u8 and is promoted in the multiplication to an int type and then sign extended to a u64. If the result of the int multiplication is greater than 0x7fffffff then the upper 32 bits will be set to 1 as a result of the sign extension. Avoid this by casting tu_size_reg to u64 to avoid sign extension and also a potential overflow. Addresses-Coverity: ("Unintended sign extension") Fixes: 1a0f7ed3abe2 ("drm/rockchip:… [View More]

https://bugzilla.kernel.org/show_bug.cgi?id=208573 Bug ID: 208573 Summary: Black screen on boot if two displays plugged in with NAVI 10 Product: Drivers Version: 2.5 Kernel Version: 5.7.8-6-MANJARO Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: … [View More]drivers_video-dri(a)kernel-bugs.osdl.org Reporter: thomas.langkamp(a)medicalschool-hamburg.de Regression: No With Radeon R9 Fury X and 2 4k displays @60hz, one LG TV@HDMI, one iiyama@DP => everything fine With new Radeon 5700 from Asus => black screen after grub menu and after some time the gpu-fans spin up a bit and the mainboard debug LED starts flashing. Then reset-button is the only option. With new Radeon 5700 XT from Gigabyte => same So I can already rule out a hardware fault. What helps: - Starting a recovery boot entry in grub - OR disconecting one display before reboot Both 5700 cards work always fine with only one display connected. If I connect the second display later, when I am already on desktop environment - also everything works. Other things I tried - changing to 30 hz then reboot - kernels from 5.4 onwards - different ports on the gpu - DP to HDMI-adapter sudo dmesg | grep amdgpu [sudo] Passwort für tom: [ 0.000000] Command line: BOOT_IMAGE=/boot/vmlinuz-5.7-x86_64 root=UUID=74886ca0-4a71-4692-aa0c-b2a539ec6b48 rw quiet loglevel=3 rd.systemd.show_status=auto rd.udev.log_priority=3 amdgpu.ppfeaturemask=0xfffd7fff resume=LABEL=swap libahci.ignore_sss=1 [ 0.000000] Kernel command line: BOOT_IMAGE=/boot/vmlinuz-5.7-x86_64 root=UUID=74886ca0-4a71-4692-aa0c-b2a539ec6b48 rw quiet loglevel=3 rd.systemd.show_status=auto rd.udev.log_priority=3 amdgpu.ppfeaturemask=0xfffd7fff resume=LABEL=swap libahci.ignore_sss=1 [ 2.597324] [drm] amdgpu kernel modesetting enabled.
