Hi Thomas, Thank you for the patches. On Tue, Jun 22, 2021 at 04:09:40PM +0200, Thomas Zimmermann wrote:Remove references to struct drm_device.irq_enabled from modern DRM drivers and core. KMS drivers enable IRQs for their devices internally. They don't have to keep track of the IRQ state via irq_enabled. For vblanking, it's cleaner to test for vblanking support directly than to test for enabled IRQs. This used to be a single patch, [1] but it's now a full series. The first 3 patches replace instances of irq_enabled that are not required. Patch 4 fixes vblank ioctls to actually test for vblank support instead of IRQs. THe rest of the patchset removes irq_enabled from all non-legacy drivers. The only exception is omapdrm, which has an internal dpendency on the field's value. For this drivers, the state gets duplicated internally. With the patchset applied, drivers can later switch over to plain Linux IRQ interfaces and DRM's IRQ midlayer can be declared legacy. v2: * keep the original test for legacy drivers in drm_wait_vblank_ioctl() (Daniel) [1] https://lore.kernel.org/dri-devel/20210608090301.4752-1-tzimmermann@xxxxxxx/ Thomas Zimmermann (22): drm/amdgpu: Track IRQ state in local device state drm/hibmc: Call drm_irq_uninstall() unconditionally drm/radeon: Track IRQ state in local device state drm: Don't test for IRQ support in VBLANK ioctls drm/komeda: Don't set struct drm_device.irq_enabled drm/malidp: Don't set struct drm_device.irq_enabled drm/exynos: Don't set struct drm_device.irq_enabled drm/kirin: Don't set struct drm_device.irq_enabled drm/imx: Don't set struct drm_device.irq_enabled drm/mediatek: Don't set struct drm_device.irq_enabled drm/nouveau: Don't set struct drm_device.irq_enabled drm/omapdrm: Track IRQ state in local device state drm/rockchip: Don't set struct drm_device.irq_enabled drm/sti: Don't set struct drm_device.irq_enabled drm/stm: Don't set struct drm_device.irq_enabled drm/sun4i: Don't set struct drm_device.irq_enabled drm/tegra: Don't set struct drm_device.irq_enabled drm/tidss: Don't use struct drm_device.irq_enabled drm/vc4: Don't set struct drm_device.irq_enabled drm/vmwgfx: Don't set struct drm_device.irq_enabled drm/xlnx: Don't set struct drm_device.irq_enabled drm/zte: Don't set struct drm_device.irq_enabledThe list seems to be missing armada, rcar-du and vkms.

Indeed. I grepped for \>irq_enabled. But some few drivers use .irq_enabled. I'll fix this in the patchset's next iteration. Thanks for double checking.
