2020-03-09drm/amd/display: Stop if retimer is not availableRodrigo Siqueira1-38/+29
Raven provides retimer feature support that requires i2c interaction in order to make it work well, all settings required for this configuration are loaded from the Atom bios which include the i2c address. If the retimer feature is not available, we should abort the attempt to set this feature, otherwise, it makes the following line return I2C_CHANNEL_OPERATION_NO_RESPONSE: i2c_success = i2c_write(pipe_ctx, slave_address, buffer, sizeof(buffer)); ... if (!i2c_success) ASSERT(i2c_success); This ends up causing problems with hotplugging HDMI displays on Raven, and causes retimer settings to warn like so: WARNING: CPU: 1 PID: 429 at drivers/gpu/drm/amd/amdgpu/../dal/dc/core/dc_link.c:1998 write_i2c_retimer_setting+0xc2/0x3c0 [amdgpu] Modules linked in: edac_mce_amd ccp kvm irqbypass binfmt_misc crct10dif_pclmul crc32_pclmul ghash_clmulni_intel snd_hda_codec_realtek snd_hda_codec_generic ledtrig_audio snd_hda_codec_hdmi snd_hda_intel amdgpu(+) snd_hda_codec snd_hda_core snd_hwdep snd_pcm snd_seq_midi snd_seq_midi_event snd_rawmidi aesni_intel snd_seq amd_iommu_v2 gpu_sched aes_x86_64 crypto_simd cryptd glue_helper snd_seq_device ttm drm_kms_helper snd_timer eeepc_wmi wmi_bmof asus_wmi sparse_keymap drm mxm_wmi snd k10temp fb_sys_fops syscopyarea sysfillrect sysimgblt soundcore joydev input_leds mac_hid sch_fq_codel parport_pc ppdev lp parport ip_tables x_tables autofs4 igb i2c_algo_bit hid_generic usbhid i2c_piix4 dca ahci hid libahci video wmi gpio_amdpt gpio_generic CPU: 1 PID: 429 Comm: systemd-udevd Tainted: G W 5.2.0-rc1sept162019+ #1 Hardware name: System manufacturer System Product Name/ROG STRIX B450-F GAMING, BIOS 2605 08/06/2019 RIP: 0010:write_i2c_retimer_setting+0xc2/0x3c0 [amdgpu] Code: ff 0f b6 4d ce 44 0f b6 45 cf 44 0f b6 c8 45 89 cf 44 89 e2 48 c7 c6 f0 34 bc c0 bf 04 00 00 00 e8 63 b0 90 ff 45 84 ff 75 02 <0f> 0b 42 0f b6 04 73 8d 50 f6 80 fa 02 77 8c 3c 0a 0f 85 c8 00 00 RSP: 0018:ffffa99d02726fd0 EFLAGS: 00010246 RAX: 0000000000000000 RBX: ffffa99d02727035 RCX: 0000000000000006 RDX: 0000000000000000 RSI: 0000000000000002 RDI: ffff976acc857440 RBP: ffffa99d02727018 R08: 0000000000000002 R09: 000000000002a600 R10: ffffe90610193680 R11: 00000000000005e3 R12: 000000000000005d R13: ffff976ac4b201b8 R14: 0000000000000001 R15: 0000000000000000 FS: 00007f14f99e1680(0000) GS:ffff976acc840000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00007fdf212843b8 CR3: 0000000408906000 CR4: 00000000003406e0 Call Trace: core_link_enable_stream+0x626/0x680 [amdgpu] dce110_apply_ctx_to_hw+0x414/0x4e0 [amdgpu] dc_commit_state+0x331/0x5e0 [amdgpu] ?

[why] Link or DIG BE can't be exposed to a higher stream bandwidth than they can handle. When DSC is required to fit the stream into the link bandwidth, DSC has to be programmed during timing programming to ensure this. Without it, intermittent issues such as black screen after S3 or a hot-plug can be seen. [how] Move DSC programming from enabling stream on link to timing setup.

Be sure to wait for the vma to be in place before we tell the GPU to execute from the wa batch. Since initialisation is mostly synchronous (or rather at some point during start up we will need to sync anyway), we can affort to do an explicit i915_vma_sync() during wa batch construction rather than check for a required await on every context switch.

There is a recipe to deadlock the kernel: submit a timeout sqe with a linked_timeout (e.g. test_single_link_timeout_ception() from liburing), and SIGKILL the process. Then, io_kill_timeouts() takes @ctx->completion_lock, but the timeout isn't flagged with REQ_F_COMP_LOCKED, and will try to double grab it during io_put_free() to cancel the linked timeout. Probably, the same can happen with another io_kill_timeout() call site, that is io_commit_cqring(). Signed-off-by: Pavel Begunkov <[email protected]> Signed-off-by: Jens Axboe <[email protected]>

2020-03-07drm/vboxvideo/vboxvideo.h: Replace zero-length array with flexible-array memberGustavo A. R. Silva1-1/+1
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest Pull kselftest update from Shuah Khan: "This consists of a cleanup patch to undo changes to global .gitignore that added selftests/lkdtm objects and add them to a local selftests/lkdtm/.gitignore. Summary of Linus's comments on local vs. global gitignore scope: - Keep local gitignore patterns in local files. - Put only global gitignore patterns in the top-level gitignore file. Local scope keeps things much better separated. It also incidentally means that if a directory gets renamed, the gitignore file continues to work unless in the case of renaming the actual files themselves that are named in the gitignore" * tag 'linux-kselftest-5.6-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest: selftest/lkdtm: Use local .gitignore

This workaround is to disable FF DOP Clock gating. The fix in B0 was backed out due to timing reasons and decided to be made permanent.
