From 766a1da2e5841959246abab9cf27c79d75636129 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Sat, 26 Apr 2003 23:32:00 +0000 Subject: Remove the map argument from DRM_*MEMORYBARRIER. Not all of the uses of DRM_*MEMORYBARRIER we had were related to an MMIO space. This means arch-specific code on the BSDs, unfortunately. Also add DRM_MEMORYBARRIER() and change the DRM_READMEMORYBARRIER()s that used to be read/write barriers to it. --- linux-core/drm_os_linux.h | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'linux-core') diff --git a/linux-core/drm_os_linux.h b/linux-core/drm_os_linux.h index eed91766..e804399a 100644 --- a/linux-core/drm_os_linux.h +++ b/linux-core/drm_os_linux.h @@ -12,8 +12,9 @@ #define DRM_READ32(map, offset) readl(((unsigned long)(map)->handle) + (offset)) #define DRM_WRITE8(map, offset, val) writeb(val, ((unsigned long)(map)->handle) + (offset)) #define DRM_WRITE32(map, offset, val) writel(val, ((unsigned long)(map)->handle) + (offset)) -#define DRM_READMEMORYBARRIER(map) mb() -#define DRM_WRITEMEMORYBARRIER(map) wmb() +#define DRM_READMEMORYBARRIER() rmb() +#define DRM_WRITEMEMORYBARRIER() wmb() +#define DRM_MEMORYBARRIER() mb() #define DRM_DEVICE drm_file_t *priv = filp->private_data; \ drm_device_t *dev = priv->dev -- cgit v1.2.3
