From 1ff494813bafa127ecba1160262ba39b2fdde7ba Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Tue, 29 Jan 2019 11:42:48 +0100 Subject: drm/irq: Ditch DRIVER_IRQ_SHARED This is only used by drm_irq_install(), which is an optional helper. For legacy pci devices this is required (due to interrupt sharing without msi/msi-x), and just making this the default exactly matches the behaviour of all existing drivers using the drm_irq_install() helpers. In case that ever becomes wrong drivers can roll their own irq handling, as many drivers already do (for other reasons like needing a threaded interrupt handler, or having an entire pile of different interrupt sources). v2: Rebase v3: Improve commit message (Emil) Cc: Sam Ravnborg Reviewed-by: Emil Velikov Signed-off-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20190129104248.26607-3-daniel.vetter@ffwll.ch --- include/drm/drm_drv.h | 22 ++++++---------------- 1 file changed, 6 insertions(+), 16 deletions(-) (limited to 'include/drm/drm_drv.h') diff --git a/include/drm/drm_drv.h b/include/drm/drm_drv.h index 0760a1d7b6c2..ca46a45a9cce 100644 --- a/include/drm/drm_drv.h +++ b/include/drm/drm_drv.h @@ -100,20 +100,20 @@ enum drm_driver_feature { * Set up DRM AGP support, see drm_agp_init(), the DRM core will manage * AGP resources.
