| | * | drm/amd: Introduce additional IPS debug flagsLeo Li2024-08-271-1/+1

DM and DC is responsible for ensuring that we are out of IPS before any DCN programming happens. Any DCN programming while we're in IPS leads to undefined behavior (mostly hangs). Because IPS intersects with all display features, the ability to disable IPS by default while ironing out the known issues is desired. However, disabing it completely will cause important features such as s0ix entry to fail. Therefore, more granular IPS debug flags are desired. [How] Extend the dc debug mask bits to include the available list of IPS debug flags. All the flags should work as documented, with the exception of IPS_DISABLE_DYNAMIC. It requires dm changes which will be done in later changes. v2: enable docs and fix docstring format Signed-off-by: Leo Li <sunpeng.li@amd.com> Reviewed-by: Aurabindo Pillai <aurabindo.pillai@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

That's not great. We're not ready to get rid of the calls to drm_panel_disable() and drm_panel_unprepare() because we're not 100% convinced that all DRM modeset drivers are properly calling drm_atomic_helper_shutdown() or drm_helper_force_disable_all() at the right times. However, having the warning show up for correctly working systems is bad. As a bit of a workaround, add some "if" tests to try to avoid the warning on correctly working systems. Also add some comments and update the TODO items in the hopes that future developers won't be too confused by what's going on here.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The i915 driver has a property to force the RGB range of an HDMI output. The vc4 driver then implemented the same property with the same semantics. KWin has support for it, and a PR for mutter is also there to support it. Both drivers implementing the same property with the same semantics, plus the userspace having support for it, is proof enough that it's pretty much a de-facto standard now and we can provide helpers for it. Let's plumb it into the newly created HDMI connector.

The first one is pretty much the generic one: it's used by i915 and vc4, and is the one used by all the compositors. The second one is used by the gma500 driver, and is a subset of the first one: it can have the values "Full" or "Limited 16:235", but lack the "Automatic" value. The third one however isn't used by any driver and documents the values "off", "auto" and "on". It's unclear where the last one comes from. It was first documented in commit 6c6a3996f2c5 ("Documentation: drm: describing drm properties exposed by various drivers") which adds a number of properties used by drivers, but without mentioning which driver was using what property. Grepping at the 6c6a3996f2c5 commit however, it looks like no driver is actually using it, and a quick look at the entire kernel history doesn't show any match either. At the time though, gma500 had an "audio" property used right next to Broadcast RGB that did have the "off", "auto" and "on" values in the same order. As such, it was probably a copy/paste or scripting error back then, and there's never been such property used in the kernel. Either way, it certainly hasn't been used in a decade or two so we can just get rid of it.

Let's mark them as deprecated and instead introduce some new macros that are more intuitive. These new macros are less optimal when an error occurs but should behave more optimally when there is no error. Specifically these new macros cause smaller code to get generated and the code size savings (less to fetch from RAM, less cache space used, less RAM used) are important. Since the error case isn't something we need to optimize for and these new macros are easier to understand and more flexible, they should be used. After converting to use these new functions, one example shows some nice savings while also being easier to understand. $ scripts/bloat-o-meter \ ...after/panel-novatek-nt36672e.ko \ ...ctx/panel-novatek-nt36672e.ko add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-988 (-988) Function old new delta nt36672e_1080x2408_60hz_init 6236 5248 -988 Total: Before=10651, After=9663, chg -9.28% Reviewed-by: Neil Armstrong <neil.armstrong@linaro.org> Reviewed-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Douglas Anderson <dianders@chromium.org> Link: https://lore.kernel.org/r/20240514102056.v5.5.Ie94246c30fe95101e0e26dd5f96e976dbeb8f242@changeid Signed-off-by: Neil Armstrong <neil.armstrong@linaro.org> Link: https://patchwork.freedesktop.org/patch/msgid/20240514102056.v5.5.Ie94246c30fe95101e0e26dd5f96e976dbeb8f242@changeid

The information is misleading at best. As described in Documentation/gpu/drm-internals.rst: The driver date, formatted as YYYYMMDD, is meant to identify the date of the latest modification to the driver. However, as most drivers fail to update it, its value is mostly useless. The DRM core prints it to the kernel log at initialization time and passes it to userspace through the DRM_IOCTL_VERSION ioctl. Stop printing the driver date at init, and start returning the empty string "" as driver date through the DRM_IOCTL_VERSION ioctl. The driver date initialization in drivers and the struct drm_driver date member can be removed in follow-up.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Print the accumulated runtime for client when printing fdinfo. Each time a query is done it first does 2 things: 1) loop through all the exec queues for the current client and accumulate the runtime, per engine class. CTX_TIMESTAMP is used for that, being read from the context image. 2) Read a "GPU timestamp" that can be used for considering "how much GPU time has passed" and that has the same unit/refclock as the one recording the runtime. RING_TIMESTAMP is used for that via MMIO. Since for all current platforms RING_TIMESTAMP follows the same refclock, just read it once, using any first engine available. This is exported to userspace as 2 numbers in fdinfo: drm-cycles-<class>: <RUNTIME> drm-total-cycles-<class>: <TIMESTAMP> Userspace is expected to collect at least 2 samples, which allows to know the client engine busyness as per: RUNTIME1 - RUNTIME0 busyness = --------------------- T1 - T0 Since drm-cycles-<class> always starts at 0, it's also possible to know if and engine was ever used by a client. It's expected that userspace will read any 2 samples every few seconds. Given the update frequency of the counters involved and that CTX_TIMESTAMP is 32-bits, the counter for each exec_queue can wrap around (assuming 100% utilization) after ~200s. The wraparound is not perceived by userspace since it's just accumulated for all the exec_queues in a 64-bit counter) but the measurement will not be accurate if the samples are too far apart. This could be mitigated by adding a workqueue to accumulate the counters every so often, but it's additional complexity for something that is done already by userspace every few seconds in tools like gputop (from igt), htop, nvtop, etc, with none of them really defaulting to 1 sample per minute or more.

It currently doesn't contain any debug information, but that can be added later. v2 * Use get_scanout_buffer() instead of the drm client API. (Thomas Zimmermann) * Add the panic reason to the panic message (Nerdopolis) * Add an exclamation mark (Nerdopolis) v3 * Rework the drawing functions, to write the pixels line by line and to use the drm conversion helper to support other formats. (Thomas Zimmermann) v4 * Use drm_fb_r1_to_32bit for fonts (Thomas Zimmermann) * Remove the default y to DRM_PANIC config option (Thomas Zimmermann) * Add foreground/background color config option * Fix the bottom lines not painted if the framebuffer height is not a multiple of the font height. * Automatically register the device to drm_panic, if the function get_scanout_buffer exists. (Thomas Zimmermann) v5 * Change the drawing API, use drm_fb_blit_from_r1() to draw the font. * Also add drm_fb_fill() to fill area with background color. * Add draw_pixel_xy() API for drivers that can't provide a linear buffer. * Add a flush() callback for drivers that needs to synchronize the buffer. * Add a void *private field, so drivers can pass private data to draw_pixel_xy() and flush(). v6 * Fix sparse warning for panic_msg and logo. v7 * Add select DRM_KMS_HELPER for the color conversion functions. v8 * Register directly each plane to the panic notifier (Sima) * Add raw_spinlock to properly handle concurrency (Sima) * Register plane instead of device, to avoid looping through plane list, and simplify code. * Replace get_scanout_buffer() logic with drm_panic_set_buffer() (Thomas Zimmermann) * Removed the draw_pixel_xy() API, will see later if it can be added back. v9 * Revert to using get_scanout_buffer() (Sima) * Move get_scanout_buffer() and panic_flush() to the plane helper functions (Thomas Zimmermann) * Register all planes with get_scanout_buffer() to the panic notifier * Use drm_panic_lock() to protect against race (Sima) v10 * Move blit and fill functions back in drm_panic (Thomas Zimmermann). * Simplify the text drawing functions. * Use kmsg_dumper instead of panic_notifier (Sima). v12 * Use array for map and pitch in struct drm_scanout_buffer to support multi-planar format later. (Thomas Zimmermann) * Better indent struct drm_scanout_buffer declaration.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to reduce the DC5->DC2 restore time, wakelocks have been introduced in DMC so the driver can tell it when registers and other memory areas are going to be accessed and keep their respective blocks awake. Implement this in the driver by adding the concept of DMC wakelocks. When the driver needs to access memory which lies inside pre-defined ranges, it will tell DMC to set the wakelock, access the memory, then wait for a while and clear the wakelock. The wakelock state is protected in the driver with spinlocks to prevent concurrency issues.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Panthor follows the lead of other recently submitted drivers with ioctls allowing us to support modern Vulkan features, like sparse memory binding: - Pretty standard GEM management ioctls (BO_CREATE and BO_MMAP_OFFSET), with the 'exclusive-VM' bit to speed-up BO reservation on job submission - VM management ioctls (VM_CREATE, VM_DESTROY and VM_BIND). The VM_BIND ioctl is loosely based on the Xe model, and can handle both asynchronous and synchronous requests - GPU execution context creation/destruction, tiler heap context creation and job submission. Those ioctls reflect how the hardware/scheduler works and are thus driver specific. We also have a way to expose IO regions, such that the usermode driver can directly access specific/well-isolate registers, like the LATEST_FLUSH register used to implement cache-flush reduction. This uAPI intentionally keeps usermode queues out of the scope, which explains why doorbell registers and command stream ring-buffers are not directly exposed to userspace. v6: - Add Maxime's and Heiko's acks v5: - Fix typo - Add Liviu's R-b v4: - Add a VM_GET_STATE ioctl - Fix doc - Expose the CORE_FEATURES register so we can deal with variants in the UMD - Add Steve's R-b v3: - Add the concept of sync-only VM operation - Fix support for 32-bit userspace - Rework drm_panthor_vm_create to pass the user VA size instead of the kernel VA size (suggested by Robin Murphy) - Typo fixes - Explicitly cast enums with top bit set to avoid compiler warnings in -pedantic mode. - Drop property core_group_count as it can be easily calculated by the number of bits set in l2_present.
