+ modeprint changes.
- All things are now called _id when they are id's.
- modeprint now accepts driver name as first argument.
|
|
- Otherwise userspace has no idea of the meaning.
|
|
not needed, hotplug will work just as well hopefully.
|
|
Idea being if you want to add new crtc/output/encoder dynamically later,
you just increase the generation counter and userspace should re-read
all the resources
|
|
|
|
Move dpms into the helper functions.
Move crtc into the encoder.
Move disable unused functions into the helper.
|
|
|
|
Okay we have crtc, encoder and connectors.
No more outputs exposed beyond driver internals
I've broken intel tv connector stuff.
Really for TV we should have one TV connector, with a sub property for the
type of signal been driven over it
|
|
Time to do some renaming on the connectors I think

Make both crtc and the command argument 32 bits to avoid any 32-on-64 compat
issues.
|
|
Enum can be of pretty much any size since C leaves the choice of size up to the implementation. So avoid using it in new interfaces like the vblank pre- & post-modeset ioctl. Thanks to hch for spotting this.
|
|
this may not survive long - just need something for testing
|
|
Also adjust i915 irq handling as it follows the 16bit'ism's
of the i8xx series.

Should be 0x08 rather than 0xa0, and shouldn't use typedefs.

Flags pending validation were stored in a misleadingly named field, 'mask'.
As 'mask' is already used to indicate pieces of a flags field which are
changing, it seems better to use a name reflecting the actual purpose of
this field. I chose 'proposed_flags' as they may not actually end up in
'flags', and in an case will be modified when they are moved over.
This affects the API, but not ABI of the user-mode interface.

Add comments about the parameters to drm_bo_do_validate, along
with comments for the DRM_BO_HINT options. Remove the 'do_wait'
parameter as it is duplicated by DRM_BO_HINT_DONT_BLOCK.

One of the costs of superioctl has been the need to perform relocations
inside the kernel. The cost of mapping the buffers to the CPU and writing
data is fairly high, especially if those buffers have been mapped and read
by the GPU.
If we assume that buffers don't move around very often, we can have the
client compute the relocations itself using the previous GPU address. When
that object doesn't move, the kernel can skip computing and writing the
updated data.
Here's a patch which adds a new field to struct drm_bo_info_req called
'presumed_offset', and a new DRM_BO_HINT_PRESUMED_OFFSET that is set when
this field has been filled in by the client.
There are two separate optimizations performed when the presumed_offset is
correct:
1. i915_exec_reloc checks to see if all previous buffer offsets were guessed
correctly. If so, there's no need for it to look at *any* of the
relocations for a buffer. When this happens, it skips the whole
relocation process, simply returning success.
2. i915_apply_reloc checks to see if the target buffer offset was guessed
correctly. If so, it skips mapping the relocatee, computing the
relocation and writing the value. If no relocations are needed, the
relocatee should never be mapped to the CPU, and so the kernel shouldn't
need to wait for any fences to pass.

I'm going to pass back a list of blob ids and lengths in the getproperty.
will need another ioctl to return the blob data as it is variable length.
|
|
This also starts to add blob property support.
someone needs to check this work for other things like ppc/x86 alignment diffs
|
|
|
|
so really want to get a list of modes per output not the global hammer list.
also we remove the mode ids and let the user pass back the full mode description
need to fix up add/remove mode for user modes now
|
|
This flag indicates that the driver is responsible for the map.
|
|
This allow the user to retrieve a list of properties for an output.
Properties can either be 32-bit values or an enum with an associated name.
Range properties are to be supported.
This API is probably not all correct, I may make properties part of the general
resource get when I think about it some more.
So basically you can create properties and attached them to whatever outputs you want,
so it should be possible to create some generics and just attach them to every output.
