From 22eae947bf76e236ba972f2f11cfd1b083b736ad Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Thu, 10 Nov 2005 22:16:34 +1100 Subject: drm: rename driver hooks more understandably Rename the driver hooks in the DRM to something a little more understandable: preinit -> load postinit -> (removed) presetup -> firstopen postsetup -> (removed) open_helper -> open prerelease -> preclose free_filp_priv -> postclose pretakedown -> lastclose postcleanup -> unload release -> reclaim_buffers_locked version -> (removed) postinit and version were replaced with generic code in the Linux DRM (drivers now set their version numbers and description in the driver structure, like on BSD). postsetup wasn't used at all. Fixes the savage hooks for initializing and tearing down mappings at the right times. Testing involved at least starting X, running glxgears, killing glxgears, exiting X, and repeating. Tested on: FreeBSD (g200, g400, r200, r128) Linux (r200, savage4) From: Eric Anholt Signed-off-by: Dave Airlie --- drivers/char/drm/drm_fops.c | 35 ++++++++++++++++------------------- 1 file changed, 16 insertions(+), 19 deletions(-) (limited to 'drivers/char/drm/drm_fops.c') diff --git a/drivers/char/drm/drm_fops.c b/drivers/char/drm/drm_fops.c index bf0a740122bf..f57f7d1a281e 100644 --- a/drivers/char/drm/drm_fops.c +++ b/drivers/char/drm/drm_fops.c @@ -45,8 +45,8 @@ static int drm_setup(drm_device_t * dev) int i; int ret; - if (dev->driver->presetup) { - ret = dev->driver->presetup(dev); + if (dev->driver->firstopen) { + ret = dev->driver->firstopen(dev); if (ret != 0) return ret; } @@ -109,8 +109,6 @@ static int drm_setup(drm_device_t * dev) * drm_select_queue fails between the time the interrupt is * initialized and the time the queues are initialized. */ - if (dev->driver->postsetup) - dev->driver->postsetup(dev); return 0; } @@ -167,7 +165,7 @@ EXPORT_SYMBOL(drm_open); * If the hardware lock is held then free it, and take it again for the kernel * context since it's necessary to reclaim buffers.
