* Merge from DRI CVS: Disable MTRRs on FreeBSD-stable to work around hangs withEric Anholt2003-04-261-10/+17

* - Add vm_paddr_t, a physical address type. This is required for systemsJake Burkholder2003-03-251-2/+2
| | | | | | | | | | | | | | | | | | where physical addresses larger than virtual addresses, such as i386s with PAE. - Use this to represent physical addresses in the MI vm system and in the i386 pmap code. This also changes the paddr parameter to d_mmap_t. - 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.

Notable changes include Radeon 8500-9100 support, PCI Radeon/Rage 128 support, transform & lighting support for Radeons, and vblank syncing support for r128, radeon, and mga. The gamma driver was removed due to lack of any users. Notes: svn path=/head/; revision=112015

* Gigacommit to improve device-driver source compatibility betweenPoul-Henning Kamp2003-03-031-14/+11
| | | | | | | | | | | | | | | | branches: Initialize struct cdevsw using C99 sparse initializtion and remove all initializations to default values. This patch is automatically generated and has been tested by compiling LINT with all the fields in struct cdevsw in reverse order on alpha, sparc64 and i386.

* Cleanup of the d_mmap_t interface.Maxime Henrion2003-02-251-6/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | - Get rid of the useless atop() / pmap_phys_address() detour. The 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.

| | | | | | | | | | | | | | | | | | | | | | | | | 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().

* Make funsetown() take a 'struct sigio **' so that the locking canAlfred Perlstein2002-05-061-1/+1
| | | | | | | | | | | | | | | | | | | 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. Notes: svn path=/head/; revision=96122
