0020a2cded We should never call drm_pci_alloc() while holding locks, due the the
calls to bus_dma.  There were multiple paths that held different locks or
no locks at all. This patch ensures that all of the calling paths drop
their lock(s) before calling drm_pci_alloc().

6f81ba0e97 Don't return EINVAL when trying to unlock.
anholt thinks that he added this check as part of some regression testing,
but it is failing at least some of the time.  I don't want to remove it
just yet.  I added a bit of debugging to help identify the issue.

149e9017bd Dont accidentally remove a filesocket which is still in use. This gives
problems when the DRM driver is loaded and the AIXGL extension is loaded

324f92b9af Disable the drm_initmap calls in radeon_cp.c, due to them resulting in improper
handling of pci resources, and mapping framebuffer leading to panics on X
startup.  The proper solution involves use of bus_alloc_resource without
RF_ACTIVE, but this code is being rewritten in DRM CVS currently, and disabling
for now doesn't remove any features, so take the easy route.

b8aa843c63 Update to DRM CVS as of 2005-04-12, bringing many changes:
- Split core DRM routines back into their own module, rather than using the
  nasty templated system like before.
- Development-class R300 support in radeon driver (requires userland pieces, of
  course).
- Mach64 driver (haven't tested in a while -- my mach64s no longer fit in the
  testbox).  Covers Rage Pros, Rage Mobility P/M, Rage XL, and some others.
- i915 driver files, which just need to get drm_drv.c fixed to allow attachment
  to the drmsub device.  Covers i830 through i915 integrated graphics.
- savage driver files, which should require minimal changes to work.  Covers the
  Savage3D, Savage IX/MX, Savage 4, ProSavage.
- Support for color and texture tiling and HyperZ features of Radeon.

98df9218da - Change the vm_mmap() function to accept an objtype_t parameter specifying
the type of object represented by the handle argument.
- Allow vm_mmap() to map device memory via cdev objects in addition to
  vnodes and anonymous memory.  Note that mmaping a cdev directly does not
  currently perform any MAC checks like mapping a vnode does.
- Unbreak the DRM getbufs ioctl by having it call vm_mmap() directly on the
  cdev the ioctl is acting on rather than trying to find a suitable vnode
  to map from.

227f9a1c58 - Add vm_paddr_t, a physical address type. This is required for systems
where physical addresses larger than virtual addresses, such as i386s

- Use this to represent physical addresses in the MI vm system and in the

- Fix printf formats to handle physical addresses >4G in the i386 memory
  detection code, and due to kvtop returning vm_paddr_t instead of u_long.

Note that this is a name change only; vm_paddr_t is still the same as
vm_offset_t on all currently supported platforms.

  device mmap handlers must now give back the physical address
  without atop()'ing it.
- Don't borrow the physical address of the mapping in the returned
  int.  Now we properly pass a vm_offset_t * and expect it to be
  filled by the mmap handler when the mapping was successful.  The
  mmap handler must now return 0 when successful, any other value
  is considered as an error.  Previously, returning -1 was the only
  way to fail.  This change thus accidentally fixes some devices
  which were bogusly returning errno constants which would have been
  considered as addresses by the device pager.
- Garbage collect the poorly named pmap_phys_address() now that it's
  no longer used.
- Convert all the d_mmap_t consumers to the new API.

I'm still not sure wheter we need a __FreeBSD_version bump for this,
since and we didn't guarantee API/ABI stability until 5.1-RELEASE.

91e97a8266 In an SMP environment post-Giant it is no longer safe to blindly
dereference the struct sigio pointer without any locking.  Change
fgetown() to take a reference to the pointer instead of a copy of the
pointer and call SIGIO_LOCK() before copying the pointer and
dereferencing it.

d49fa1ca6e In continuation of early fileop credential changes, modify fo_ioctl() to
accept an 'active_cred' argument reflecting the credential of the thread
initiating the ioctl operation.

- Change fo_ioctl() to accept active_cred; change consumers of the
  fo_ioctl() interface to generally pass active_cred from td->td_ucred.
- In fifofs, initialize filetmp.f_cred to ap->a_cred so that the
  invocations of soo_ioctl() are provided access to the calling f_cred.
  Pass ap->a_td->td_ucred as the active_cred, but note that this is
  required because we don't yet distinguish file_cred and active_cred
  in invoking VOP's.
- Update kqueue_ioctl() for its new argument.
- Update pipe_ioctl() for its new argument, pass active_cred rather
  than td_ucred to MAC for authorization.
- Update soo_ioctl() for its new argument.
- Update vn_ioctl() for its new argument, use active_cred rather than
  td->td_ucred to authorize VOP_IOCTL() and the associated VOP_GETATTR().

e649887b1e Make funsetown() take a 'struct sigio **' so that the locking can
be done internally.

Ensure that no one can fsetown() to a dying process/pgrp.  We need
to check the process for P_WEXIT to see if it's exiting.  Process
groups are already safe because there is no such thing as a pgrp
zombie, therefore the proctree lock completely protects the pgrp
from having sigio structures associated with it after it runs
funsetownlst.

Add sigio lock to witness list under proctree and allproc, but over
proc and pgrp.

Seigo Tanimura helped with this.
