| | | | | | | | | We need to initialise the DBI interface and the code for it got missed in the original merge as it's in a daft place. This will need moving but lets get it added first. Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* gma500: being abstracting out devices a bit moreAlan Cox2011-07-0510-538/+847
| | | | | | | | | | | | | | We really want to move towards a completely abstracted interface rather than having tons of per chip junk in the same files. Begin with the power code which is probably the worst offender. Add a set of methods, initialise a dev_priv->ops pointer and rip the chip specifics out of the power code. While we are it pick up the display init bits. So we know it's now chip specifics clean remove the psb_ naming from it.

* gma500: 2D acceleration tidyingAlan Cox2011-07-051-6/+13
| | | | | | | | | | | We have a FIXME to do the power management for which the framework now exists, and we also need to deal with an erratum. Some operations exactly 8 pixels wide or high fail. The work around is to do two smaller ones (see the Intel released X driver bits) but for console quite frankly if it's 8bits wide and/or high its not worth it so fall back.

| | | | | | | | | | | If we get a user frame buffer destroyed which is being displayed then clean up the mess nicely. We can now run a slightly modified modetest including setting modes, and handling crashes. Modetest still blows up but this is because libdrm 2.4.25 is busted.

| | | | | | | | | | | | We need this for the framebuffer in order to ensure that the kernel framebuffer layer can handle it when using KMS. Except for the base framebuffer this isn't a concern.

Grabbing the tag early in ->lldd_execute_task let's us drop the isci_host_can_queue() and ->was_tag_assigned_by_user infrastructure. ->was_tag_assigned_by_user required the task context to be duplicated in request-local buffer. With the tci established early we can build the task_context directly into its final location and skip a memcpy. With the task context buffer at a known address at request construction we have the opportunity/obligation to also fix sgl handling. This rework feels like it belongs in another patch but the sgl handling and task_context are too intertwined. 1/ fix the 'ab' pair embedded in the task context to point to the 'cd' pair in the task context (previously we were prematurely linking to the staging buffer). 2/ fix the broken iteration of pio sgls that assumes all sgls are relative to the request, and does a dangerous looking reverse lookup of physical address to virtual address.
