2024-08-29drm/i915: deprecate the i915.modeset module parameterJani Nikula1-2/+1
The i915.modeset parameter doesn't really provide any useful benefit over the nomodeset kernel parameter. Anything that i915.modeset does can be achieved via nomodeset or not probing i915 at all. Unfortunately, the i915.modeset parameter is widely referenced on various forums, and removing it is not that simple. Start off by deprecating it in the module parameter documentation, and logging a warning message on non-default values.

2024-05-16drm/i915: Support replaying GPU hangs with captured context imageTvrtko Ursulin1-0/+5
When debugging GPU hangs Mesa developers are finding it useful to replay the captured error state against the simulator. But due various simulator limitations which prevent replicating all hangs, one step further is being able to replay against a real GPU. This is almost doable today with the missing part being able to upload the captured context image into the driver state prior to executing the uploaded hanging batch and all the buffers. To enable this last part we add a new context parameter called I915_CONTEXT_PARAM_CONTEXT_IMAGE. It follows the existing SSEU configuration pattern of being able to select which context to apply against, paired with the actual image and its size. Since this is adding a new concept of debug only uapi, we hide it behind a new kconfig option and also require activation with a module parameter. Together with a warning banner printed at driver load, all those combined should be sufficient to guard against inadvertently enabling the feature. In terms of implementation we allow the legacy context set param to be used since that removes the need to record the per context data in the proto context, while still allowing flexibility of specifying context images for any context. Mesa MR using the uapi can be seen at: https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/27594 v2: * Fix whitespace alignment as per checkpatch. * Added warning on userspace misuse. * Rebase for extracting ce->default_state shadowing. v3: * Rebase for I915_CONTEXT_PARAM_LOW_LATENCY.

2024-04-22drm/i915/dmc: change how to disable DMC firmware using module paramJani Nikula1-1/+2
The distinction between the dmc_firmware_path module param being NULL and the empty string "" is problematic. It's not possible to set the parameter back to NULL via sysfs or debugfs. Remove the distinction, and consider NULL and the empty string to be the same thing, and use the platform default for them. This removes the possibility to disable DMC (and runtime PM) via i915.dmc_firmware_path="". Instead, use "/dev/null" as the magic firmware path to skip DMC firmware loading and disable runtime PM. v2: Add support for i915.dmc_firmware_path="/dev/null" (Gustavo) Cc: Gustavo Sousa <[email protected]> Cc: Lucas De Marchi <[email protected]> Reviewed-by: Gustavo Sousa <[email protected]> Acked-by: Lucas De Marchi <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/8695aca8a6643e36bb680bc2dcab97c637e70b00.1713519628.git.jani.nikula@intel.com Signed-off-by: Jani Nikula <[email protected]>

This reverts commit 0d82a0d6f5561af8dea7011d1b7cae510021723e. The commit failed to take into account that the parameter duplication and debugfs for char * parameters were subtly different between i915 core and display, and caused the DMC and PM to be disabled.

There are new cases where we want to block i915 probe, such as when experimenting or developing the new Xe driver. But also, with the new hybrid cards, users or developers might want to use i915 only on integrated and fully block the probe of the i915 for the discrete. Or vice versa. There are even older development and validation reasons, like when you use some distro where the modprobe.blacklist is not present. But in any case, let's introduce a more granular control, but without introducing yet another parameter, but using the existent force_probe one. Just by adding a ! in the begin of the id in the force_probe, like in this case where we would block the probe for Alder Lake: $ insmod i915.ko force_probe='!46a6' v2: Take care of '*' and '!*' cases as pointed out by Gustavo and Jani.

Use DECLARE_DYNDBG_CLASSMAP across DRM: - in .c files, since macro defines/initializes a record - in drivers, $mod_{drv,drm,param}.c ie where param setup is done, since a classmap is param related - in drm/drm_print.c since existing __drm_debug param is defined there, and we ifdef it, and provide an elaborated alternative. - in drm_*_helper modules: dp/drm_dp - 1st item in makefile target drivers/gpu/drm/drm_crtc_helper.c - random pick iirc. Since these modules all use identical CLASSMAP declarations (ie: names and .class_id's) they will all respond together to "class DRM_UT_*" query-commands: :#> echo class DRM_UT_KMS +p > /proc/dynamic_debug/control NOTES: This changes __drm_debug from int to ulong, so BIT() is usable on it. DRM's enum drm_debug_category values need to sync with the index of their respective class-names here. Then .class_id == category, and dyndbg's class FOO mechanisms will enable drm_dbg(DRM_UT_KMS, ...). Though DRM needs consistent categories across all modules, thats not generally needed; modules X and Y could define FOO differently (ie a different NAME => class_id mapping), changes are made according to each module's private class-map. No callsites are actually selected by this patch, since none are class'd yet.

2021-12-14drm/i915: Test all device memory on probingChris Wilson1-0/+3
This extends the previous sanitychecking of device memory to read/write all the memory on the device during the device probe, ala memtest86, as an optional module parameter: i915.memtest=1. This is not expected to be fast, but a reasonably thorough verfification that the device memory is accessible and doesn't return bit errors. v2: Rebased.

2021-06-09drm/i915/uc: Use platform specific defaults for GuC/HuC enablingJohn Harrison1-1/+1
The meaning of 'default' for the enable_guc module parameter has been updated to accurately reflect what is supported on current platforms. So start using the defaults instead of forcing everything off. Although, note that right now, the default is for everything to be off anyway. So this is not a change for current platforms.

2021-01-19drm/i915/dp: Allow forcing specific interfaces through enable_dpcd_backlightLyude Paul1-1/+1
Since we now support controlling panel backlights through DPCD using both the standard VESA interface, and Intel's proprietary HDR backlight interface, we should allow the user to be able to explicitly choose between one or the other in the event that we're wrong about panels reliably reporting support for the Intel HDR interface. So, this commit adds support for this by introducing two new enable_dpcd_backlight options: 2 which forces i915 to only probe for the VESA interface, and 3 which forces i915 to only probe for the Intel backlight interface (might be useful if we find panels in the wild that report the VESA interface in their VBT, but actually only support the Intel backlight interface). v3: * Rebase Signed-off-by: Lyude Paul <[email protected]> Reviewed-by: Jani Nikula <[email protected]> Cc: [email protected] Cc: Vasily Khoruzhick <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]
2020-08-17drm/i915: Initial implementation of PSR2 selective fetchJosé Roberto de Souza1-0/+5
All GEN12 platforms supports PSR2 selective fetch but not all GEN12 platforms supports PSR2 hardware tracking(aka RKL). This feature consists in software programming registers with the damaged area of each plane this way hardware will only fetch from memory those areas and sent the PSR2 selective update blocks to panel, saving even more power. But as initial step it is only enabling the full frame fetch at every flip, the actual selective fetch part will come in a future patch. Also this is only handling the page flip side, it is still completely missing frontbuffer modifications, that is why the enable_psr2_sel_fetch parameter was added. v3: - calling intel_psr2_sel_fetch_update() during the atomic check phase (Ville) BSpec: 55229 Cc: Ville Syrjälä <[email protected]> Cc: Imre Deak <[email protected]> Cc: Gwan-gyeong Mun <[email protected]> Cc: Rodrigo Vivi <[email protected]> Cc: Dhinakaran Pandiyan <[email protected]> Reviewed-by: Gwan-gyeong Mun <[email protected]> Signed-off-by: José Roberto de Souza <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected] Signed-off-by: Rodrigo Vivi <[email protected]>
