2023-07-25drm/amdkfd: avoid svm dump when dynamic debug disabledAlex Sierra
Set dynamic_svm_range_dump macro to avoid iterating over SVM lists from svm_range_debug_dump when dynamic debug is disabled. Otherwise, it could drop performance, specially with big number of SVM ranges. Make sure both svm_range_set_attr and svm_range_debug_dump functions are dynamically enabled to print svm_range_debug_dump debug traces.

2023-07-24drm/omapdrm: Set VM flags in GEM-object mmap functionThomas Zimmermann
Use the mmap callback in struct drm_gem_object_funcs to set the VM flags. Replace a number of mmap helpers in omapdrm with their GEM helper counterparts. Generate DRM's file-operations instance with GEM's DEFINE_DRM_GEM_FOPS. The omapdrm driver uses DRM's drm_gem_mmap() helper to prepare the VMA structure. It then modifies the resulting VMA state in its own helper omap_gem_mmap_obj(). The patch improves this by setting up the VMA in the mmap callback in drm_gem_object_funcs, which is called from within drm_gem_mmap(). Omapdrm's omap_gem_mmap() and omap_gem_mmap() can then be removed from the driver. A call to drm_gem_mmap() is sufficient for the mmap operation. Finally, with the omap functions gone, the drivers file_ops in omapdriver_fops can be generated with DEFINE_DRM_GEM_FOPS, which sets DRM's default helpers. v2: * detailed commit message (Javier) * do not set VM_PFNMAP Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Acked-by: Maxime Ripard <mripard@kernel.org> Cc: Tomi Valkeinen <tomi.valkeinen@ideasonboard.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230707083422.18691-9-tzimmermann@suse.de

Tegra uses DMA-able memory, which has to be acessed with CPU ops for system-memory. Store the framebuffer's vmap address in struct fb_info.screen_buffer. The currently used field 'screen_base' is for I/O memory.

2023-07-24drm/tegra: Set fbdev FBINFO_VIRTFB flagThomas Zimmermann
Mark the framebuffer with FBINFO_VIRTFB. The framebuffer range is in DMA-able memory and should be accessed with the CPU's regular memory ops. v2: * drop FBINFO_DEFAULT Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Acked-by: Maxime Ripard <mripard@kernel.org> Cc: Thierry Reding <thierry.reding@gmail.com> Cc: Mikko Perttunen <mperttunen@nvidia.com> Acked-by: Thierry Reding <treding@nvidia.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230707083422.18691-5-tzimmermann@suse.de

Use fbdev's DMA helpers for fbdev emulation. They are equivalent to the previously used system-memory helpers, so no functional changes here.

2023-07-24fbdev: Add fb_ops init macros for framebuffers in DMA-able memoryThomas Zimmermann
Add initializer macros for struct fb_ops for framebuffers in DMA-able memory areas. Also add a corresponding Kconfig token. As of now, this is equivalent to system framebuffers and mostly useful for labeling drivers correctly. A later patch may add a generic DMA-specific mmap operation. Linux offers a number of dma_mmap_*() helpers for different use cases.
