Eric Anholt ea7b4fdc22 Fix the possibility of sleeping with locks held in sysctls by copying the 
data into temporary variables with the lock held then outputting to
    sysctls with the lock released. Rearranged a little extra code to aid
    this. Note that drm_memory_debug.h hasn't had this fix applied, but I
    consider that code to be just about dead anyway.

Eric Anholt 6b0424fdcd Clean up BSD MTRR handling. The NetBSD code is untested, but it's my best 
shot.

Eric Anholt 0cf1887139 - SMPng lock the DRM. This is only partial -- there are a few code paths 
used by root (the X Server) which are not locked. However, it should
    deal with lost-IRQ issues on -current which I think people have been
    experiencing but I am unable to reproduce (though I understand why they
    would occur, because of a bug of mine). Note that most of the locking
    (DRM_LOCK()/UNLOCK()) is all covered by Giant still, so it doesn't
    matter yet.
- Remove locking on FreeBSD-stable and NetBSD. These are covered by the
    fact that there is no reentrancy of the kernel except by interrupts,
    which are locked using spldrm()/splx() instead.

Eric Anholt 59fbe01fea Clean up extra zeroing of dev->dma, and use calloc to take advantage of 
M_ZERO.

Eric Anholt 63ce8af555 Fix probing on 2.5+ kernels, which require that drivers have .id_table set. 
We use PCI_ANY_ID to ask that our probe is called for every available
    device.

Eric Anholt 2950f9e682 - Move IRQ functions from drm_dma.h to new drm_irq.h and disentangle them 
from __HAVE_DMA. This will be useful for adding vblank sync support to
    sis and tdfx. Rename dma_service to irq_handler, which is more
    accurately what it is.
- Fix the #if _HAVE_DMA_IRQ in radeon, r128, mga, i810, i830, gamma to have
    the right number of underscores. This may have been a problem in the
    case that the server died without doing its DRM_IOCTL_CONTROL to
    uninit.

Eric Anholt ff58476011 - Converted Linux drivers to initialize DRM instances based on PCI IDs, not 
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)

Eric Anholt 9fbfb7ca6a Some code cleanups done while working on locking. Reduces always-true 
tests, excessive indenation, convoluted handling of errors, or code
    duplication.

Eric Anholt 929536172c Stylistic preparation for SMPng locking work: DRM_LOCK/DRM_UNLOCK have side 
effects, so make them look like functions (add parenthesis).

Eric Anholt e187d665e4 Add an MIT-style copyright, assigned to myself, to these files. I think 
I've touched enough of the code here, and there was no previous
    copyright. Do some drive-by style fixes while I'm here.

Eric Anholt 89dd7be3dd Axe more old gamma DMA infrastructure. 2003-10-02 07:02:34 +00:00
Eric Anholt a6b84f73e1 Mostly whitespace cleanups and style(9) fixes focused on "if(" -> "if (" 
Change some nearby memset()s to bzero()s or to calloc allocations to
    take advantage of M_ZERO). Reverse some error tests to reduce high
    levels of indentation. Move the sg_cleanup() call out of the maplist
    loop in DRM(takedown)-- I can't see any need for it to be inside.

Eric Anholt f634f68759 These files were missed in the SiS DRM commit. 2003-08-29 20:54:26 +00:00
Eric Anholt fabc64dd57 Port the SiS DRM to FreeBSD. This includes the ability for the DRM to 
allocate framebuffer memory without sisfb, and a new ioctl to be used
    by the X Server which tells the DRM what region of framebuffer memory
    to allocate from. Also fixes a possibility to panic the kernel I
    believe. Tested on linux with sisfb and FreeBSD (without sisfb) with
    new DRI only.

Eric Anholt ad78a613a4 - Remove $FreeBSD$ tags as they weren't too useful and merges are now being 
done through perforce.
- Add copyright headers to drm_os_*bsd.h, still need to research the other
    copyright-less files better.
