[PATCH 00/23] kill drm cruft with fire

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

It's that time of the year again when the weather gets crappy, people
depressed and danvet wades through drm cruft. Not that any of this is
related in any way.

Actually I only wanted to port users of drm_mm to the new interfaces,
completing a work I've started a while ago. It lead to a littel detour.

Patches 1-10 kill drm_sman (hereby reducing the number of users of the old
drm_mm interface by one). I don't have either sis or via hw but given
- how lightly the dri1 removal went down
- you can't really ebay this hw anymore (at least not here, I've tried)
- and that no one really changes much in them anymore (last time was me a
  year ago, killing cruft)

I think the risk is worth it. Worst case I expect to some oops-decoding
because this doesn't change neither userspace nor hw facing code, only pure
kernel book-keeping.

Patches 11-17 clean the reclaim_buffers support by the drm core by moving
everything into driver specific preclose functions. I've noticed this
horrid stuff while writing the buffer tracking code for via/sis.

Patches 18-20 rip out the dma queue code, which was totally unused. The two
risky steps of that surgery are split out.

Patches 21-23 finish this series by killing a few random smaller things
I've noticed.

Entire pile tested on my i810, that's the last fully working dri1 setup I
still have. The reclaim_buffers rework actually improves things there.

Two patches have a potential userspace abi impact, one is i810 specific
(didn't break anything in testing), the other breaks libdrm that is older
than 10 years (by killing proc).

The drm fd release path looks now much less scary with this series (mostly
due to the reclaim_buffers rework), but there's still the context support
seemingly only used by via left. I might look into that as soon as I can
get these images of horribly slaugthered kittens out of my brain ...

Review, flames highly welcome.

Cheers, Daniel
