* | drm/bochs: use devm_ioremap_wc() to map framebufferYan Zhao2024-09-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Opt for devm_ioremap_wc() over devm_ioremap() when mapping the framebuffer. Using devm_ioremap() results in the VA being mapped with PAT=UC-, which considerably slows down drm_fb_memcpy(). In contrast, devm_ioremap_wc() maps the VA with PAT set to WC, leading to better performance on platforms where access to UC memory is much slower than WC memory. Here's the performance data measured in a guest on the physical machine "Sapphire Rapids XCC". With host KVM honors guest PAT memory types, the effective memory type for this framebuffer range is - WC when devm_ioremap_wc() is used - UC- when devm_ioremap() is used. The data presented is an average from 10 execution runs.

* | drm/bochs: Use GEM SHMEM helpers for memory managementThomas Zimmermann2024-09-062-43/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace GEM VRAM with GEM SHMEM in bochs. The new memory manager stores buffer objects in system memory. Makes the driver's memory management more reliably. Most of the changes are hidden in external helpers that allocate buffers. Replacing DRM_GEM_VRAM_DRIVER with DRM_GEM_SHMEM_DRIVER_OPS swaps these. With GEM VRAM, the video memory was updated directly by the DRM client. The biggest change within bochs is in atomic_update, which now updates video memory via memcpy() from the BO in system memory. Shadow-plane helpers maintaining the pointers to the buffer's data, so bochs doesn't have to. The update is triggered by each page flip's call to the framebuffer's dirty helper. The driver supports damage clipping to minimize memcpy() overhead. The advantage of GEM SHMEM is that it makes memory management more reliable. Given DRM's double buffering during page flips, the minimum amount of video memory is three times the maximum consumption in some pathological cases. For example, if the maximum size of a GEM buffer is 1920x1080-32 (i.e., 32-bit FullHD), the buffer size is 8 MiB. Display hardware has to provide at lease 24 MiB to reliably page flip such configurations. This cannot always be guaranteed and bochs already contains code to rule out <4 MiB configurations. With GEM SHMEM, only 8 MiB of video memory are required for the given example. Unsupported modes can be sorted out easily.

* | drm/bochs: Use regular atomic helpersThomas Zimmermann2024-09-061-45/+132
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove the simple display pipeline in favor of the regular atomic helpers in bochs. The simple-pipe helpers are considered deprecated in DRM. This effectivly inlines the simple-pipe code for plane and CRTC support. Instead of a single update helper, there's now a mode-set helper for the CRTC and an update helper for the plane. The encoder changes type from NONE ot VIRTUAL. Removing simple-pipe helpers from bochs will allow for related cleanups in GEM VRAM helpers.

| | | | | | | | | | | | | | | | | | | | | | Add support for the drm_panic module, which displays a user-friendly message to the screen when a kernel panic occurs. v8: * Replace get_scanout_buffer() with drm_panic_set_buffer() (Thomas Zimmermann) v9: * Revert to using get_scanout_buffer() (Sima) * move get_scanout_buffer() to plane helper functions (Thomas Zimmermann) v12: * Use array for map and pitch in struct drm_scanout_buffer to support multi-planar format later.

* drm/arcpgu: Convert to platform remove callback returning voidUwe Kleine-König2023-11-211-4/+2
| | | | | | | | | | | | | | | | | | | The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.
