2021-07-13drm/amdgpu: Return error if no RASLuben Tuikov2-17/+38
In amdgpu_ras_query_error_count() return an error if the device doesn't support RAS. This prevents that function from having to always set the values of the integer pointers (if set), and thus prevents function side effects--always to have to set values of integers if integer pointers set, regardless of whether RAS is supported or not--with this change this side effect is mitigated. Also, if no pointers are set, don't count, since we've no way of reporting the counts. Also, give this function a kernel-doc.

We were getting a depmod error: depmod: ERROR: Cycle detected: drm_kms_helper -> drm -> drm_kms_helper It looks like the rule is that drm_kms_helper can call into drm, but drm can't call into drm_kms_helper. That means we've got to move the DP AUX backlight support into drm_dp_helper. NOTE: as part of this, I didn't try to do any renames of the main registration function. Even though it's in the drm_dp_helper, it still feels very parallel to drm_panel_of_backlight().

2021-07-13drm/vkms: Use dma-buf mapping from shadow-plane state for composingThomas Zimmermann3-13/+15
Store the shadow-buffer mapping's address in struct vkms_composer and use the value when composing the output. It's the same value as stored in the GEM SHMEM BO, but frees the composer code from its dependency on GEM SHMEM. Using struct dma_buf_map is how framebuffer access is supposed to be. The long-term plan is to perform all framebuffer access via struct dma_buf_map and avoid the details of accessing I/O and system memory.

This change also fixes a problem where IGT kms_flip tests would create a segmentation fault within vkms. The driver's prepare_fb function did not report an error if a BO's vmap operation failed.

2021-07-11drm/i915/gt: Fix -EDEADLK handling regressionVille Syrjälä1-1/+1
The conversion to ww mutexes failed to address the fence code which already returns -EDEADLK when we run out of fences. Ww mutexes on the other hand treat -EDEADLK as an internal errno value indicating a need to restart the operation due to a deadlock. So now when the fence code returns -EDEADLK the higher level code erroneously restarts everything instead of returning the error to userspace as is expected. To remedy this let's switch the fence code to use a different errno value for this. -ENOBUFS seems like a semi-reasonable unique choice. Apart from igt the only user of this I could find is sna, and even there all we do is dump the current fence registers from debugfs into the X server log. So no user visible functionality is affected. If we really cared about preserving this we could of course convert back to -EDEADLK higher up, but doesn't seem like that's worth the hassle here. Not quite sure which commit specifically broke this, but I'll just attribute it to the general gem ww mutex work.

2021-07-11drm/i915: Invoke another _DSM to enable MUX on HP Workstation laptopsKai-Heng Feng3-0/+25
On HP Fury G7 Workstations, graphics output is re-routed from Intel GFX to discrete GFX after S3. This is not desirable, because userspace will treat connected display as a new one, losing display settings. The expected behavior is to let discrete GFX drives all external displays. The platform in question uses ACPI method \_SB.PCI0.HGME to enable MUX. The method is inside the another _DSM, so add the _DSM and call it accordingly. I also tested some MUX-less and iGPU only laptops with that _DSM, no regression was found. v4: - Rebase. - Change the DSM name to avoid confusion. - Move the function call to intel_opregion. v3: - Remove BXT from names. - Change the parameter type. - Fold the function into intel_modeset_init_hw(). v2: - Forward declare struct pci_dev.

2021-07-09drm/i915: Add release id versionLucas De Marchi3-2/+18
Besides the arch version returned by GRAPHICS_VER(), new platforms contain a "release id" to make clear the difference from one platform to another. The release id number is not formally defined by hardware until future platforms that will expose it via a new GMD_ID register. For the platforms we support before that register becomes available we will set the values in software and we can set them as we please. So the plan is to set them so we can group different features under a single GRAPHICS_VER_FULL() check. After GMD_ID is used, the usefulness of a "full version check" will be greatly reduced and will be mostly used for deciding workarounds and a few code paths. So it makes sense to keep it as a separate field from graphics_ver. Also, as a platform with `release == n` may be closer feature-wise to `n - 2` than to `n - 1`, use the word "release" rather than the more common "minor" for this This is a mix of 2 independent changes: one by me and the other by Matt Roper. v2: - Reword commit message to make it clearer why we don't call it "minor" (Matt Roper and Tvrtko) - Rename variables s/*_ver_release/*_rel/ and print them in a single line formatted as {ver}.{rel:2} (Jani and Matt Roper) Cc: Matt Roper <matthew.d.roper@intel.com> Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com> Signed-off-by: Matt Roper <matthew.d.roper@intel.com> Reviewed-by: Matt Roper <matthew.d.roper@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210707235921.2416911-2-lucas.demarchi@intel.com

2021-07-09drm/panel: add basic DP AUX backlight supportRajeev Nandan1-0/+108
Some panels support backlight control over DP AUX channel using VESA's standard backlight control interface. Using new DRM eDP backlight helpers, add support to create and register a backlight for those panels in drm_panel to simplify the panel drivers. The panel driver with access to "struct drm_dp_aux" can create and register a backlight device using following code snippet in its probe() function: err = drm_panel_dp_aux_backlight(panel, aux); if (err) return err; Then drm_panel will handle backlight_(enable|disable) calls similar to the case when drm_panel_of_backlight() is used. Currently, we are not supporting one feature where the source device can combine the backlight brightness levels set through DP AUX and the BL_PWM_DIM eDP connector pin. Since it's not required for the basic backlight controls, it can be added later.
