2006-02-20Formatting cleanup, dead code removal. Remove N() namespacing macro,Adam Jackson
useless. Remove SIGIO handling functions as they're server-only and properly belong in libdri.
2005-12-31Initialize sv.drm_dd_minor to "don't care" along with dd_major, to appeaseEric Anholt
valgrind.

makedev() as a function call that elfloader can't resolve. Originally Gentoo Bug #41962, reported by Ryan Breen, fix feedback from Ryan Lortie.
2004-07-07Make drm/libdrm/xf86drm.c matchJon Smirl
xc/xc/programs/Xserver/hw/xfree86/os-support/linux/drm/xf86drm.c so that it matches the prototypes in xf86drm.h XFree86 bug: Reported by: Submitted by: Reviewed by: Obtained from:
2003-10-23- Introduce a new ioctl, DRM_IOCTL_SET_VERSION. This ioctl allows theEric Anholt
server or client to notify the DRM that it expects a certain version of the device dependent or device independent interface. If the major doesn't match or minor is too large, EINVAL is returned. A major of -1 means that the requestor doesn't care about that portion of the interface. The ioctl returns the actual versions in the same struct. - Introduce DRM DI interface version 1.1. If the server requests version 1.1, then the DRM sets the unique itself according to the busid of the device it probed, which may then be accessed as normal using getunique. - Request version 1.1 in libdrm's drmOpenByBusID, allowing the X Server to request based on a BusID. Introduce a wrapper for DRM_IOCTL_SET_VERSION and bump libdrm minor version. - Pass the busid in DRIScreenInit if libdrm can handle both a busid and name. This allows drmOpenByBusID to be used to find the DRM instead of just the driver name, which allows us in the future to tie a DRM more strongly to the device it probed to. Introduce a function DRICreatePCIBusID which creates a busid in the form pci:oooo:bb:dd.f similar to linux's pci_name() function. This matches the format used by the DRM in version 1.1. libdrm knows how to match both this format and the old PCI:b:d:f format. - Use the new DRICreatePCIBusID function in the *_dri.c to request the new, more exact busid format.

2001-07-30Merge the multihead-1-0-0 branch into the trunk, with the exception of theDavid Dawes
glide header files. The changes include: - Brian Paul's changes to the tdfx client-side 3D driver to make it dlopen() the correct glide library (Voodoo3 or Voodoo5). This allows both types of the glide library to co-exist, and allows Voodoo3/Voodoo5 cards to be mixed in multi-head configs. - DRM kernel driver changes to allow a driver to set up multiple instances (minor numbers), one for each card present that the driver supports. This is currently implemented and tested only for the tdfx DRM driver. - Add some missing missing <stdarg.h> includes. - Some log message cleanups. - Change the 2D tdfx driver to access VGA legacy registers via their PCI I/O space access points rather than their legacy addresses, and fix some problems with the way the VGA-related bits are initialised. Status: - With these changes, multi-head direct rendering works with multiple Voodoo3 and/or Voodoo5 cards. This has been tested with two PCI Voodoo3 cards and an AGP Voodoo5 card, and all permutations of those. Caveats: - Xinerama is not supported. If Xinerama is enabled, then direct rendering gets disabled. - The text mode on secondary screens will show junk after the X server exits. - On some hardware, starting the X server on multiple 3dfx cards will result in a hard lockup. One workaround is to enable APIC support in a uni-processor kernel, or use an SMP kernel.
2001-07-20Remove module name hacks because we aren't going to implement this anymoreJeff Hartmann
because of Linus' comments
2001-07-18Add module version name at a lower layer of the code, allows things to beJeff Hartmann
more flexible and allow older module versions to still work. Might not be final code if we move over to DRI kernel module version, but will be if we use XFree86 version. + Only build tdfx.o instead of tdfx-4_1_0.o since tdfx.o has never changed its API.
