This patch series contains the gpu sharing layer for kernel that I've mentioned before. It should apply against Linus's git tree.
Why do we want this?
Currently the kernel cannot provide both the fb and drm drivers with access to the device model and this means the drm cannot get any suspend/resume callbacks.
This layer attempts to fix this problem by adding a bus for the gpu drivers
to attach to. Currently a lowlevel binding driver is needed along with optional
fb and drm components.
This patch series only covers the generic code and radeon initially, I'll
probably target intel next.
All the patches are available at:
http://www.skynet.ie/~airlied/patches/gpu
I think maybe the radeonfb patch may not make it pass the list filter..
Dave.

Initially this layer wouldn't be needed, but I'd like to add some awareness to the drivers, so the drm can tell the fb to stop doing stuff and vice-versa if necessary.... but perhaps that could be done with a generic layer also.. or via the lowlevel driver I have...

It's been bubbling its way up my todo too, as agpgart is starting to get bug reports due to conflicts when the EDAC drivers or watchdog drivers 'claim' the south bridge ID before agp gets a chance to init. Someone sent me some patches a few weeks back, but I seem to have mislaid them. I'll turf them up and get the sender to send them to lkml. They should at the least, make a starting point.

I have a idea. Greg asked me to move my display class away from the class_device method. One of the nice things about using class_device_register is that it handles all the attributes for you :-) So while going throught the core code for device handling I discovered that struct device has a struct class. I found it alot easier to have class field in the device point to the class you want to use. With device registeration the class is setup up for you. The idea was to have the a linked list of classes inside of struct device. Then have a way to register/unregister that class with the device. This way struct device and struct device_driver are per hardware but struct class could be used to handle different interfaces to that same hardware. What do you think? I could do a example with hardware that registers a fbdev drivers as well as a backlight. Plus nobody is using the class field in struct device at this time. ^ permalink raw reply [flat|nested] 18+ messages in thread

Or would this layer still be needed? Please do this. Its not only fbdev but backlight and display support. Note display support is not main stream yet. Greg sent me a email about the DRM team needing a CRT class as well. That will be a different discussion. Plus some cards have tuners as well. So this device sharing is needed. It would also be really nice to prevent driver collisions. For example vesafb and a fbdev driver controlling the same hardware or acpi backlight versus the graphics card backlight support. ^ permalink raw reply [flat|nested] 18+ messages in thread
