riastradh | uvm(9): fo_mmap caller guarantees positive size.
No functional change intended, just sprinkling assertions to make it
clearer.
|
| 1.14 |
| 19-Dec-2021 |
riastradh | Make ourselves less dependent on drmP.h, removed upstream.
This causes some trouble as CONFIG_* lines might not be appropriately
defined. A few declarations remain in drmP.h so it's not gone.

riastradh | drm/drm_drv.h for struct drm_device

riastradh | Catch up with function renames
reference -> get, unreference -> put
Author: Maya Rashish <maya@NetBSD.org>
|
| 1.11 |
| 19-Dec-2021 |
riastradh | Need <sys/file.h> to dereference struct file.
|
| 1.10 |
| 19-Dec-2021 |
riastradh | Pass drm_file, not file, pointer to drm_vma_node_is_allowed.
|
| 1.9 |
| 27-Aug-2018 |
riastradh | Rename drm_mmap_* -> drm_legacy_mmap_* like upstream.
|
| 1.8 |
| 27-Aug-2018 |
riastradh | Need drm_legacy.h for legacy mmap stuff.
|
| 1.7 |
| 27-Aug-2018 |
riastradh | Need to use new <drm/drm_gem.h> for GEM stuff.
|
| 1.6 |
| 09-Mar-2015 |
riastradh | branches: 1.6.16; 1.6.18;
Apply access control to gem mmap.
|
| 1.5 |
| 26-Jul-2014 |
riastradh | branches: 1.5.2; 1.5.4; 1.5.6;
Let the drm driver decide what part of what object gets mmapped.
Pass the file around too so radeon/ttm can get at it to verify access.
Add drm_gem_or_legacy_mmap_object for drivers to choose the previous
behaviour, like i915.
|
| 1.4 |
| 16-Jul-2014 |
riastradh | Make it build and boot on my test machines.
Screen blanks on boot on the Ivy Bridge system with
DRM error in cpt_serr_int_handler: PCH transcoder A FIFO underrun
But after that everything is OK. Appears to be an upstream problem.
To investigate...
I think there's a cache flushing issue somewhere -- there are little
display artefacts on my T60.

| 1.3 |
| 01-May-2014 |
riastradh | branches: 1.3.2; 1.3.4;
Tweak some DRM GEM page indexing crap.
- Fix order of subtraction in drm_mmap_paddr_locked.
- Address GEM objects' pages from 0, not from the mmap cookie.
- Check page alignment earlier in mmap code paths.
- Sprinkle kasserts throughout.
Still doesn't fix the garbage that is sometimes being scribbled all
over kernel memory!

commit 983d308cb8f602d1920a8c40196eb2ab6cc07bd2
Author: Chris Wilson <chris%chris-wilson.co.uk@localhost>
Date: Mon Jan 26 10:47:10 2015 +0000
agp/intel: Serialise after GTT updates
Include <sys/atomic.h> for membar_producer.
(Why didn't this fail in my build?)
Pass cache-related flags through to the GTT on pre-SNB devices.
I had assumed for ages this would increase the amount of caching and
thereby increase the chance of stale caches leading to rendering
glitches. But apparently I was wrong, and failing to pass these
through was causing all sorts of problems!
Dedup the NetBSD portion of the code (ok Riastradh), no functional change.
Don't return events that are too large and leave them in the list.
Apply access control to gem mmap.
fix gcc is stupid.
