* - Remove test_and_set_bit() macro. It is unused since r255037.Jung-uk Kim2013-08-291-5/+3
| | | | | | | | | | | - Relax atomic_read() and atomic_set() macros. Linux does not require any memory barrier. Also, these macros may be even reordered or optimized away according to the API documentation: https://www.kernel.org/doc/Documentation/atomic_ops.txt Notes: svn path=/head/; revision=255039

| | | | | | | | | | | | | | calls ns8250_bus_ipend() almost immediately after ns8250_bus_attach(). As it appears, a line break condition is being signalled for almost all received characters due to this. A delay of 150ms seems enough to allow the H/W to settle and to avoid the problem. More analysis is needed, but for now a regression has been addressed. Reported by: kevlo@ Tested by: kevlo@ Notes: svn path=/head/; revision=255031

ETHER_ALIGN. This could be tweaked some more, or removed since it probably doesn't matter much for x86 (and the x86 class of machines this driver will be used on).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This driver is based on Linux 3.8 and a previous effort by kan@. More informations about this project can be found on the FreeBSD wiki: https://wiki.freebsd.org/AMD_GPU The driver is split into: sys/dev/drm2: The driver sources. sys/modules/drm2/radeonkmw: The driver main kernel module's Makefile. sys/modules/drm2/radeonkmsfw: All firmware kernel module Makefiles. There's one directory and one Makefile for each firmware. sys/contrib/dev/drm2/radeonkmsfw: All firmware binary sources. tools/tools/drm/radeon Tools to update firmwares or regenerate some headers. Merging the driver to FreeBSD 9.x may be possible but not a priority for now.

* vga_pci: Add API to map the Video BIOSJean-Sébastien Pédron2013-08-252-0/+105

Additionally, one can determine if a given device was the default display at boot time using the following new function: void vga_pci_unmap_bios(device_t dev, void *bios); Notes: svn path=/head/; revision=254882

* drm/ttm: Fix unmap of buffer objectJean-Sébastien Pédron2013-08-252-6/+28
| | | | | | | | | | | | | | | | | | Add a new ttm_bo_release_mmap() function to unmap pages in a vm_object_t. Pages are freed when the buffer object is later released. This function is called in ttm_bo_unmap_virtual_locked(), replacing Linux' unmap_mapping_range(). In particular this is called when a buffer object is about to be moved, so that its mapping is invalidated. However, we don't use this function in ttm_bo_vm_dtor(), because the vm_object_t is already marked as OBJ_DEAD and the pages will be unmapped.

The fix is to revert the above commit and only take the lock where we need it, around the call to ->sync_obj_ref. v2: Fixup things noticed by Maarten Lankhorst: - Brown paper bag locking bug. - No need for kzalloc if we clear the entire thing on the next line. - check for bo->sync_obj (totally unlikely race, but still someone else could have snuck in) and clear fbo->sync_obj if it's cleared already.

While working on a new kms driver that uses memcpy, if I overallocated bo's up to the memory limits, and eviction failed, then machine would oops soon after due to having an active bo with an already freed drm_mm embedded in it, freeing it a second time didn't end well.

Instead of spinning with a new seqno every time we keep the current one, but still drop all other reservations we hold. Only when we succeed, we try to get back our other reservations again.
