From db7fce3983ad9b3deebda450121af4aaf6809ce2 Mon Sep 17 00:00:00 2001 From: Christian König Date: Fri, 11 May 2012 14:57:18 +0200 Subject: drm/radeon: replace vmram_mutex with mclk_lock v2 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit It is a rw_semaphore now and only write locked while changing the clock. Also the lock is renamed to better reflect what it is protecting. v2: Keep the ttm_vm_ops on IGPs Signed-off-by: Christian König Reviewed-by: Jerome Glisse --- drivers/gpu/drm/radeon/radeon_pm.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'drivers/gpu/drm/radeon/radeon_pm.c') diff --git a/drivers/gpu/drm/radeon/radeon_pm.c b/drivers/gpu/drm/radeon/radeon_pm.c index 5b37e283ec38..9dc0b54fe3e3 100644 --- a/drivers/gpu/drm/radeon/radeon_pm.c +++ b/drivers/gpu/drm/radeon/radeon_pm.c @@ -251,7 +251,7 @@ static void radeon_pm_set_clocks(struct radeon_device *rdev) return; mutex_lock(&rdev->ddev->struct_mutex); - mutex_lock(&rdev->vram_mutex); + down_write(&rdev->pm.mclk_lock); mutex_lock(&rdev->ring_lock); /* gui idle int has issues on older chips it seems */ @@ -303,7 +303,7 @@ static void radeon_pm_set_clocks(struct radeon_device *rdev) rdev->pm.dynpm_planned_action = DYNPM_ACTION_NONE; mutex_unlock(&rdev->ring_lock); - mutex_unlock(&rdev->vram_mutex); + up_write(&rdev->pm.mclk_lock); mutex_unlock(&rdev->ddev->struct_mutex); } -- cgit v1.2.3
