postinit and version were replaced with generic code in the Linux DRM
(drivers now set their version numbers and description in the driver
structure, like on BSD). postsetup wasn't used at all. Fixes the savage
hooks for initializing and tearing down mappings at the right times.
Testing involved at least starting X, running glxgears, killing
glxgears, exiting X, and repeating.
Tested on: FreeBSD (g200, g400, r200, r128) Linux (r200, savage4)
just a single instance. Moved the PCI ID lists from <card>_drv.c in BSD
to <card>.h. The PCI ID lists include a driver private field, which may
be used by drivers for chip family or other information. Based on work
by jonsmirl.
- Make tdfx_drv.c and tdfx.h match other drivers.
- Fixed up linking of sis shared files.
Tested with Radeon and SiS on Linux and FreeBSD, including a Linux setup
with
2 SiS cards in a machine, but only one head being used (with DRI)
agp chipsets to drm_agpsupport.h, redid the card detection common code
to use a structure (avoids endian porting issues), changed the tdfx
driver to use the kernel pci id '#defines'
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.
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.
- Fix old-style DMA for gamma driver (please test).
- Pull out IRQ handling into drm_dma.h (please test on i810, gamma).
- Lots of general cleanups, remove compiler warnings etc.
against 2.2.18pre21
As usual, since all 2.4.0-test* kernels set LINUX_VERSION_CODE to the same
value, if you are running a 2.4.0-test kernel, you MUST be running
2.4.0-test11-pre4 or later (although anything after 2.4.0-test11-pre1
should work fine -- I tested with pre4/pre5). I expect 2.2.x support to
continue to work for all recent kernels, but I tested with 2.2.18pre21
-- we use the old intermodule symbol communication for 2.2.x kernels,
so they should all continue to work.
several fixes including: (Jeff) Really disable multitexture (Broken
since Mesa 3.4 integration.)
(Jeff) Various changes in mga_state.c in the kernel module, which includes
a fix to the bug where the first OGL application hangs the machine
w/out rendering anything. This also includes defines for the warp
registers so they are easily human readable.
(Rik and Jeff) Fixed all the schedule loops in the kernel to look like they
are supposed too.
(Jeff) Configurable agp modes: Add the option "AGPMode2x" or "AGPMode4x" to
your XF86Config file.
(Rik) Various cleanups to the mga kernel driver to make it easier to read
and debug.
(Rik) Removed alot of DRM_DEBUG statements from the kernel driver.
