linux-next: merge conflict between drm-misc and sound trees
by Lukas Wunner 14 Mar '18

14 Mar '18

Dear Stephen, when rebuilding linux-next you're going to see a merge conflict in: sound/pci/hda/hda_intel.c betwen commit: 1ba8f9d30817 ("ALSA: hda: Add a power_save blacklist") from the sound tree and commit: 07f4f97d7b4b ("vga_switcheroo: Use device link for HDA controller") from the drm-misc tree. I recommend fixing it up like below. -- >8 -- @@@ -2284,16 -2298,22 +2303,30 @@@ chip->running = 1; azx_add_card_list(chip); + /* + * The discrete GPU cannot power down unless the HDA controller runtime + * suspends, so activate runtime PM on codecs even if power_save == 0. + */ + if (use_vga_switcheroo(hda)) + list_for_each_codec(codec, &chip->bus) + codec->auto_runtime_pm = 1; + - snd_hda_set_power_save(&chip->bus, power_save * 1000); + val = power_save; + #ifdef CONFIG_PM + if (val == -1) { + const struct snd_pci_quirk *q; + + val = CONFIG_SND_HDA_POWER_SAVE_DEFAULT; + q = snd_pci_quirk_lookup(chip->pci, power_save_blacklist); + if (q && val) { + dev_info(chip->card->dev, "device %04x:%04x is on the power_save blacklist, forcing power_save to 0\n", + q->subvendor, q->subdevice); + val = 0; + } + } + #endif /* CONFIG_PM */ + snd_hda_set_power_save(&chip->bus, val * 1000); - if (azx_has_pm_runtime(chip) || hda->use_vga_switcheroo) + if (azx_has_pm_runtime(chip)) pm_runtime_put_autosuspend(&pci->dev); out_free:

[PATCH] [v2] drm/i915/pmu: avoid -Wmaybe-uninitialized warning
by Arnd Bergmann 14 Mar '18

14 Mar '18

The conditional spinlock confuses gcc into thinking the 'flags' value might contain uninitialized data: drivers/gpu/drm/i915/i915_pmu.c: In function '__i915_pmu_event_read': arch/x86/include/asm/paravirt_types.h:573:3: error: 'flags' may be used uninitialized in this function [-Werror=maybe-uninitialized] The code is correct, but it's easy to see how the compiler gets confused here. This avoids the problem by pulling the lock outside of the function into its only caller.

[PATCH v2 0/7] Modernize vga_switcheroo by using device link for HDA
by Lukas Wunner 14 Mar '18

14 Mar '18

Modernize vga_switcheroo by using a device link to enforce a runtime PM dependency from an HDA controller to the GPU it's integrated into, v2. Changes since v1: - Replace patch [1/7] to use pci_save_state() / pci_restore_state() for consistency between runtime PM code path of bound and unbound devices. (Rafael, Bjorn) - Patch [5/7]: Drop an unnecessary initialization. (Bjorn) Rephrase error message on failed link addition for clarity. Link to v1: https://www.spinics.net/lists/dri-devel/msg165889.html Testing on more machines would be greatly appreciated, particularly Nvidia Optimus or AMD PowerXpress. The series is based on 4.16-rc3. To test it on 4.15, you need to cherry-pick 7506dc798993 and 2fa6d6cdaf28. For your convenience I've pushed a 4.15-based branch to: https://github.com/l1k/linux/commits/switcheroo_devlink_v2 Minimal test procedure: - Note well: Recent Optimus require that a Mini-DP or HDMI cable is plugged in on boot for the HDA device to be present. - Check that HDA, GPU and root port autosuspend when not in use: cat /sys/bus/pci/devices/0000:01:00.1/power/runtime_status # HDA cat /sys/bus/pci/devices/0000:01:00.0/power/runtime_status # GPU cat /sys/bus/pci/devices/0000:00:01.0/power/runtime_status # Root Port - Check that all three autoresume when accessing the HDA: hdajacksensetest -c 1 - Unbind the HDA controller: echo 0000:01:00.1 > /sys/bus/pci/drivers/snd_hda_intel/unbind Wait for GPU to power off, then rebind the HDA controller: echo 0000:01:00.1 > /sys/bus/pci/drivers/snd_hda_intel/bind Check dmesg for errors, try accessing HDA with hdajacksensetest. - If your laptop uses the root port's _PR3 to cut power to the GPU: Unbind the GPU: echo 0000:01:00.0 > /sys/bus/pci/drivers/{nouveau,amdgpu,radeon}/unbind Allow runtime PM on the GPU: echo auto > /sys/bus/pci/devices/0000:01:00.0/power/control Wait for GPU to power off, then rebind it: echo 0000:01:00.0 > /sys/bus/pci/drivers/{nouveau,amdgpu,radeon}/bind Check dmesg for errors. If you see any then we may need to perform further actions in pci_pm_runtime_resume(), see patch [1/7]. Thanks, Lukas Lukas Wunner (6): PCI: Make pci_wakeup_bus() & pci_bus_set_current_state() public vga_switcheroo: Update PCI current_state on power change vga_switcheroo: Deduplicate power state tracking vga_switcheroo: Use device link for HDA controller vga_switcheroo: Let HDA autosuspend on mux change drm/nouveau: Runtime suspend despite HDA being unbound Rafael J.

[Bug 102905] [R600] Miscompilation of TGSI to VLIW causes artifacts in Gallium Nine with Crysis2 bump mapping
by bugzilla-daemon＠freedesktop.org 14 Mar '18

https://bugs.freedesktop.org/show_bug.cgi?id=102905 Bug ID: 102905 Summary: [R600] Miscompilation of TGSI to VLIW causes artifacts in Gallium Nine with Crysis2 bump mapping Product: Mesa Version: 17.2 Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 Assignee: dri-devel(a)lists.freedesktop.org Reporter: iive(a)yahoo.com QA Contact: dri-devel(a)lists.freedesktop.org In short, the miscompilation happens at "cmp" instruction where the destination register is also one of the source registers. I suspect that the problem is caused by breaking "cmp" on two operands that are executed in different VLIW, thus the result of the first one changes the outcome of the second. Using a temporal register in "cmp" workarounds the issue. The bug is NOT related to Shader Backend. Artifacts are still visible with "R600_DEBUG=nosb". A D3D9 apitrace could be obtained from the ixit Nine ftp. The bug is also tracked at https://github.com/iXit/Mesa-3D/issues/288 . My hardware is Radeon HD5670 (Evergreen, Redwood). Not reproducible on Radeon SI.

by yannick fertre 13 Mar '18

13 Mar '18

Version 3: - Replace some pr_error, pr_warn or pr_info by dev_error, dev_warn & dev_info. - Refresh stm32f769-disco_defconfig with last modification done on v2018.3-rc4. - rework include files ordering. Version 2: - Replace debug log by pr_error, pr_warn or pr_info. - Rework bridge between ltdc & dsi panel - Rework backligh management (with or witout gpio) - Rework panel otm8009a - Add new panel raydium rm68200 Version 1: - Initial commit This serie contains all patchsets needed for displaying a splash screen on the stm32f769 disco board. A new config has been created configs/stm32f769-disco_defconfig. This is necessary due to the difference of panels between stm32f769-disco & stm32f746-disco boards.

[PATCH v3 0/6] DRM/i915 cgroup integration
by Matt Roper 13 Mar '18

13 Mar '18

This is the third iteration of the work previously posted here: (v1) https://lists.freedesktop.org/archives/intel-gfx/2018-January/153156.html (v2) https://www.mail-archive.com/dri-devel@lists.freedesktop.org/msg208170.html The high level goal of this work is to allow non-cgroup-controller parts of the kernel (e.g., device drivers) to register their own private policy data for specific cgroups. That mechanism is then made use of in the i915 graphics driver to allow GPU priority to be assigned according to the cgroup membership of the owning process. Please see the v1 cover letter linked above for a more in-depth explanation and justification. Key changes in v3 of this series: * The cgroup core interfaces have been redesigned as suggested by Tejun. The cgroup core now supports the following: void cgroup_priv_install(struct cgroup *cgrp, struct cgroup_priv *priv); struct cgroup_priv *cgroup_priv_lookup(struct cgroup *cgrp, const void *key); void cgroup_priv_free(struct cgroup *cgrp, const void *key); * Consumers of this interface may want to test the filesystem permissions of a cgroup to decide whether to allow custom syscalls or ioctls to operate on a cgroup's private data. A new cgroup_permission(cgrp_fd, mask) function has been added to make this easier. * The i915 code looks up cgroup private data for 'current' rather than drm_file->pid to account for the device handle passing done by DRI3 (i.e., the process that opened the device filehandle isn't necessarily the same process issuing ioctl's on it). * Other minor updates/changes based on feedback from Chris Wilson and Tejun Heo. One open question on the i915 side of this work is whether we need to limit the "priority offset" that can be assigned via cgroup (and if so, what it should be limited to). At the moment we make the assumption that cgroup-based priority will be assigned by a privileged system administrator / system integrator, so we accept any integer value they choose to assign to the priority, even if it doesn't make sense. As noted on previous iterations, the i915 userspace consumer for the ioctl here is a simple i-g-t tool that will be sent shortly as a followup on the intel-gfx list. The tool itself is pretty trivial, but that's intetional; the "real" userspace consumer of this work would usually be something like a sysv-init script or systemd recipe that would call that simple tool in an appropriate way to accomplish the desired policy for a specific system. Matt Roper (6): cgroup: Allow registration and lookup of cgroup private data cgroup: Introduce task_get_dfl_cgroup() cgroup: Introduce cgroup_permission() drm/i915: cgroup integration drm/i915: Introduce 'priority offset' for GPU contexts drm/i915: Add context priority & priority offset to debugfs (v2) drivers/gpu/drm/i915/Makefile | 1 + drivers/gpu/drm/i915/i915_cgroup.c | 214 ++++++++++++++++++++++++++++++++ drivers/gpu/drm/i915/i915_debugfs.c | 3 + drivers/gpu/drm/i915/i915_drv.c | 5 + drivers/gpu/drm/i915/i915_drv.h | 25 ++++ drivers/gpu/drm/i915/i915_gem_context.c | 7 +- drivers/gpu/drm/i915/i915_gem_context.h | 9 ++ include/linux/cgroup-defs.h | 38 ++++++ include/linux/cgroup.h | 102 +++++++++++++++ include/uapi/drm/i915_drm.h | 13 ++ kernel/cgroup/cgroup.c | 56 +++++++++ 11 files changed, 470 insertions(+), 3 deletions(-) create mode 100644 drivers/gpu/drm/i915/i915_cgroup.c -- 2.14.3

[PATCH libdrm] meson: don't use compiler.has_header
by Dylan Baker 13 Mar '18

13 Mar '18

Meson's compiler.has_header is completely useless, it only checks that a header exists, not whether it's usable. This creates problems if a header contains a conditional #error declaration, like so: > #if __x86_64__ > # error "Doesn't work with x86_64!" > #endif Compiler.has_header will return true in this case, even when compiling for x86_64. This is useless. Instead, we'll do a compile check so that any #error declarations will be treated as errors, and compilation will work. Fixes compilation on x32 architecture.
