2023-03-31drm/radeon: Implement client-based fbdev emulationThomas Zimmermann
Implement fbdev emulation on top of struct drm_client and its helpers. Replaces ad-hoc interfaces for restoring and closing fbdev emulation with per-client callbacks for hotplugging, restoring and unregistering. A single function, radeon_fbdev_setup(), starts fbdev emulation after the DRM device has been registered. Hence, fbdev acts like a regular DRM client. The setup call prepares the fbdev emulation and invokes connector hotplugging. The first successful hotplug event initializes fbdev emulation with a framebuffer, device file, etc. Unregistering depends on the hotplug status. Fully initialized emulation is cleaned up through drm_fb_helper_unregister_info() and fb_destroy. For prepared-only setups, unregistering unprepares the emulation and releases all resources. In both cases, fbdev emulation will be cleaned up.

2022-08-23drm/radeon: Drop legacy MST supportLyude Paul
Right now, radeon is technically the only non-atomic driver still making use of the MST helpers - and thus the final user of all of the legacy MST helpers. Originally I was going to look into seeing if we could move legacy MST into the radeon driver itself, however: * SI and CIK both can use amdgpu, which still supports MST * It currently doesn't work according to my own testing. I'm sure with some troubleshooting we could likely fix it, but that brings me to point #2: * It was never actually enabled by default, and is still marked as experimental in the module parameter description * If people were using it, someone probably would have probably seen a bug report about how it is currently not functional by now. That certainly doesn't appear to be the case, since before getting access to my own hardware I had to go out of my way to try finding someone to help test whether this legacy MST code even works - even amongst AMD employees. * Getting rid of this code and only having atomic versions of the MST helpers to maintain is likely going to be a lot easier in the long run, and will make it a lot easier for others contributing to this code to follow along with what's happening. FWIW - if anyone still wants this code to be in the tree and has a good idea of how to support this without needing to maintain the legacy MST helpers (trying to move them would probably be acceptable), I'm happy to suggestions. But my hope is that we can just drop this code and forget about it. I've already run this idea by Harry Wentland and Alex Deucher a few times as well.

2021-11-27drm: Move nomodeset kernel parameter to the DRM subsystemJavier Martinez Canillas
The "nomodeset" kernel cmdline parameter is handled by the vgacon driver but the exported vgacon_text_force() symbol is only used by DRM drivers. It makes much more sense for the parameter logic to be in the subsystem of the drivers that are making use of it. Let's move the vgacon_text_force() function and related logic to the DRM subsystem. While doing that, rename it to drm_firmware_drivers_only() and make it return true if "nomodeset" was used and false otherwise. This is a better description of the condition that the drivers are testing for.

On the Loongson64 platform used with Radeon GPU, shutdown or reboot failed when console=tty is in the boot cmdline. radeon_suspend_kms() puts the hw in the suspend state, especially set fb state as FBINFO_STATE_SUSPENDED: if (fbcon) { console_lock(); radeon_fbdev_set_suspend(rdev, 1); console_unlock(); } Then avoid to do any more fb operations in the related functions: if (p->state != FBINFO_STATE_RUNNING) return; So call radeon_suspend_kms() in radeon_pci_shutdown() for Loongson64 to fix this issue, it looks like some kind of workaround like powerpc.

2021-05-26drm/radeon: Implement mmap as GEM object functionThomas Zimmermann
Moving the driver-specific mmap code into a GEM object function allows for using DRM helpers for various mmap callbacks. This change also allows to support prime-based mmap via DRM's helper drm_gem_prime_mmap(). Permission checks are implemented by drm_gem_mmap(), with an additional check for radeon_ttm_tt_has_userptr() in the GEM object function. The function radeon_verify_access() is now unused and has thus been removed. As a side effect, radeon_ttm_vm_ops and radeon_ttm_fault() are now implemented in amdgpu's GEM code. v3: * remove unnecessary checks from mmap (Christian) v2: * rename radeon_ttm_vm_ops and radeon_ttm_fault() to radeon_gem_vm_ops and radeon_gem_fault() (Christian) * fix commit description (Alex) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Christian König <christian.koenig@amd.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210525151055.8174-4-tzimmermann@suse.de

2020-11-06drm/<drivers>: Constify struct drm_driverDaniel Vetter
Only the following drivers aren't converted: - amdgpu, because of the driver_feature mangling due to virt support. Subsequent patch will address this. - nouveau, because DRIVER_ATOMIC uapi is still not the default on the platforms where it's supported (i.e. again driver_feature mangling) - vc4, again because of driver_feature mangling - qxl, because the ioctl table is somewhere else and moving that is maybe a bit too much, hence the num_ioctls assignment prevents a const driver structure. - arcpgu, because that is stuck behind a pending tiny-fication series from me. - legacy drivers, because legacy requires non-const drm_driver. Note that for armada I also went ahead and made the ioctl array const. Only cc'ing the driver people who've not been converted (everyone else is way too much). v2: Fix one misplaced const static, should be static const (0day) v3: - Improve commit message (Sam) Acked-by: Sam Ravnborg <sam@ravnborg.org> Cc: kernel test robot <lkp@intel.com> Acked-by: Maxime Ripard <mripard@kernel.org> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Sam Ravnborg <sam@ravnborg.org> Cc: Dave Airlie <airlied@redhat.com> Cc: Gerd Hoffmann <kraxel@redhat.com> Cc: virtualization@lists.linux-foundation.org Cc: Harry Wentland <harry.wentland@amd.com> Cc: Leo Li <sunpeng.li@amd.com> Cc: Alex Deucher <alexander.deucher@amd.com> Cc: Christian König <christian.koenig@amd.com> Cc: Eric Anholt <eric@anholt.net> Cc: Maxime Ripard <mripard@kernel.org> Cc: Ben Skeggs <bskeggs@redhat.com> Cc: nouveau@lists.freedesktop.org Signed-off-by: Daniel Vetter <daniel.vetter@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20201104100425.1922351-5-daniel.vetter@ffwll.ch
2020-11-06drm/radeon: Stop changing the drm_driver structDaniel Vetter
With only the kms driver left, we can fold this in. This means we need to move the ioctl table, which means one additional ioctl must be defined in headers. Also there's a conflict between the radeon_init macro and the module init function, so rename the module functions to avoid that.

2020-02-26drm/radeon: Inline drm_get_pci_devDaniel Vetter
It's the last user, and more importantly, it's the last non-legacy user of anything in drm_pci.c. The only tricky bit is the agp initialization. But a close look shows that radeon does not use the drm_agp midlayer (the main use of that is drm_bufs for legacy drivers), and instead could use the agp subsystem directly (like nouveau does already). Hence we can just pull this in too. A further step would be to entirely drop the use of drm_device->agp, but feels like too much churn just for this patch.

Bail from the pci_driver probe function instead of from the drm_driver load function. This avoid /dev/dri/card0 temporarily getting registered and then unregistered again, sending unwanted add / remove udev events to userspace. Specifically this avoids triggering the (userspace) bug fixed by this plymouth merge-request: https://gitlab.freedesktop.org/plymouth/plymouth/merge_requests/59 Note that despite that being an userspace bug, not sending unnecessary udev events is a good idea in general.
