Summary: make DRM_MODULES="radeon" fails on ppc; typo + x86-
specific call [with patch]
Product: DRI
Version: DRI CVS
Platform: Macintosh
OS/Version: Linux
Status: NEW
Severity: enhancement
Priority: P2
Component: DRM modules
AssignedTo: dri-devel@lists.sourceforge.net
ReportedBy: [EMAIL PROTECTED]
Trying to run make DRM_MODULES="radeon" on ppc linux, there are two problems:
/home/me/x11/clean/drm/linux-core/drm_vm.c: In function âdrm_io_protâ:
/home/me/x11/clean/drm/linux-core/drm_vm.c:60: error: âmapâ undeclared
(first
use in this function)
/home/me/x11/clean/drm/linux-core/drm_vm.c:60: error: (Each undeclared
identifier is reported only once
/home/me/x11/clean/drm/linux-core/drm_vm.c:60: error: for each function it
appears in.)
This is just a typo; -> needs to be changed to _. Once this is fixed, the
module compiles, but does not load, as it refers to wbinvd (in
drm_ttm_ipi_handler in drm_ttm.c), which doesn't exist on ppc.
ati_pcigart.c contains the following code:
#if defined(__i386__) || defined(__x86_64__)
wbinvd();
#else
mb();
#endif
When this replaces the unconditional use of wbinvd in drm_ttm.c, the module
loads and direct rendering works (I'm using a ATI Technologies Inc RV350
[Mobility Radeon 9600 M10] in a Powerbook).
This code probably shouldn't be duplicated, but I'm not aware of what coding
standards are used by this project, sorry.
