Robert, The patch applied cleanly (8.0 Stable from last week), but on rebuilding the kernel (make buildkernel) I get the following: cc -c -O -pipe -std=c99 -g -Wall -Wredundant-decls -Wnested-externs -Wstrict-prototypes -Wmissing-prototypes -Wpointer-arith -Winline -Wcast-qual -Wundef -Wno-pointer-sign -fformat-extensions -nostdinc -I. -I/usr/src/sys -I/usr/src/sys/contrib/altq -D_KERNEL -DHAVE_KERNEL_OPTION_HEADERS -include opt_global.h -fno-common -finline-limit=8000 --param inline-unit-growth=100 --param large-function-growth=1000 -mno-align-long-strings -mpreferred-stack-boundary=2 -mno-mmx -mno-3dnow -mno-sse -mno-sse2 -mno-sse3 -ffreestanding -fstack-protector -Werror /usr/src/sys/dev/drm/drm_sysctl.c cc1: warnings being treated as errors /usr/src/sys/dev/drm/drm_sysctl.c: In function 'drm_vm_info': /usr/src/sys/dev/drm/drm_sysctl.c:206: warning: format '%016jx' expects type 'uintmax_t', but argument 5 has type 'long unsigned int' *** Error code 1 Stop in /usr/obj/usr/src/sys/PSV. *** Error code 1 Stop in /usr/src. *** Error code 1 Stop in /usr/src. > -----Original Message----- > From: Robert Noland [mailto:rnoland@FreeBSD.org] > Sent: Saturday, December 19, 2009 1:10 PM > To: greg@rowes.org > Cc: 'Steve Polyack'; 'Andriy Gapon'; freebsd-x11@FreeBSD.org; 'John > Baldwin' > Subject: RE: PCI Radeon 9250 - DRI/DRM in 8.0-RELEASE > > On Sat, 2009-12-12 at 17:36 -0500, Greg Rowe wrote: > > The system is still running the pagezero patch if that makes any > difference? > > Ok, you can get rid of that. > > I wasn't able to fix this quite like I wanted to, but this should work. > The fix that I was intending to do, ended up meaning that I had to work > on our mmap implementation, which I did, but won't be committed until it > is reviewed.
