From e7d4a26913ba3a4949ac36280925062948ee21ce Mon Sep 17 00:00:00 2001 From: Ian Romanick Date: Tue, 18 Sep 2007 11:03:08 -0700 Subject: Fix ioc32 compat layer Previously any ioctls that weren't explicitly listed in the compat ioctl table would fail with ENOTTY. If the incoming ioctl number is outside the range of the table, assume that it Just Works, and pass it off to drm_ioctl. This make the fence related ioctls work on 64-bit PowerPC. --- linux-core/drm_ioc32.c | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) (limited to 'linux-core/drm_ioc32.c') diff --git a/linux-core/drm_ioc32.c b/linux-core/drm_ioc32.c index 558376de..0188154e 100644 --- a/linux-core/drm_ioc32.c +++ b/linux-core/drm_ioc32.c @@ -1051,8 +1051,13 @@ long drm_compat_ioctl(struct file *filp, unsigned int cmd, unsigned long arg) drm_ioctl_compat_t *fn; int ret; + + /* Assume that ioctls without an explicit compat routine will "just + * work".
