The data is now in kernel space, copied in/out as appropriate according to the
This results in DRM_COPY_{TO,FROM}_USER going away, and error paths to deal
with those failures. This also means that XFree86 4.2.0 support for i810 DRM
is lost.
|
|
As a fallout, replace filp storage with file_priv storage for "unique
identifier of a client" all over the DRM. There is a 1:1 mapping, so this
should be a noop. This could be a minor performance improvement, as everything
on Linux dereferenced filp to get file_priv anyway, while only the mmap ioctls
went the other direction.

With this, all modules build again.

- use a timer for disabling vblank events to avoid enable/disable calls too
often
- make i915 work with pre-965 chips again (would like to structure this
better, but this hack works on my test system)

|
- use correct refcount variable in get/put routines
- extract counter update from drm_vblank_get
- make signal handling callback per-crtc
- update interrupt handling logic, drivers should use drm_handle_vblank
- move wakeup and counter update logic to new drm_handle_vblank routine
- fixup usage of get/put in light of counter update extraction
- fix longstanding bug in signal code, update pending counter only
*after* we're sure we'll setup signal handling
|
|
- move pre/post modeset ioctl to core
- fixup i915 buffer swap
- fix outstanding signal count code
- create new core vblank init routine
- test (works with glxgears)
- simplify i915 interrupt handler

of vblank interrupt in order to save power.

Introduce tile members for future tiled buffer support.
Allow user-space to explicitly define a fence-class.
Remove the implicit fence-class mechanism.
64-bit wide buffer object flag member.

These require that the status page be referenced by a pointer in GTT, rather
than phsyical memory. So, we have the X Server allocate that memory and tell
us the address, instead.

Lots of changes to merge with alanh's latest stuff:
o fix use of fb->pitch now that it has the right value
o add new helper for finding the CRTC given an FB
o fix new fb_probe/fb_remove functions to take a CRTC
o fixup callers of new FB routines
o port drm_fb changes to intel_fb
o check for errors after creating fb buffer object
o go back to using cfb_imageblit since the accel stubs aren't ready

places).
Add new FB hooks to the drm driver structure and make i915 use them for an
Intel specific FB driver. This will allow acceleration and better handling
of the command stream.

shared-core/i915_init.c - reconcile with airlied's new code

We need to keep a list of user created fbs to nuke on master exit.
We also need to use the bo properly.

When the kernel driver is loaded it sets up a lot of stuff..
it tears down the same stuff on unload.
This add a new map type called DRM_DRIVER which means the driver will clean the mapping up
and fix up the map cleaner

This is required to use TTM to allocate the ring buffer.
|
|
|
|
Always use dev_priv->sarea_priv->pf_current_page directly. This allows clients
to modify it as well while they hold the HW lock, e.g. in order to sync pages
between pipes.
|
|
The assumption is that synchronous flips are not isolated usually, and waiting
for all of them could result in stalling the pipeline for long periods of time.
Also use i915_emit_mi_flush() instead of an old-fashioned way to achieve the
same effect.
|
|
Unfortunately, emitting asynchronous flips during vertical blank results in
tearing. So we have to wait for the previous vertical blank and emit a
synchronous flip.
|
|
Pages are tracked independently on each pipe.
Bump the minor version for 3D clients to know page flipping is usable, and
bump driver date.
|
|
Leave it to the client to wait for the flip to complete when necessary,
but wait for a previous flip to complete before emitting another one. This
should help avoid unnecessary stalling of the ring due to pending flips.
Call i915_do_cleanup_pageflip() unconditionally in preclose.

Buffer object driver for via.

Fixed - to System memory copies are implemented by
flipping in a cache-coherent TTM,
blitting to it, and then flipping it out.

Memory types are either fixed (on-card or pre-bound AGP) or not fixed
(dynamically bound) to an aperture. They also carry information about:
1) Whether they can be mapped cached.
2) Whether they are at all mappable.
3) Whether they need an ioremap to be accessible from kernel space.
In this way VRAM memory and, for example, pre-bound AGP appear
identical to the memory manager.
This also makes support for unmappable VRAM simple to implement.

|
Yes, this driver supports the new memory manager, that is indicated by the
version number being >= 1.7.
