radeonfb: Fix resume from D3Cold on some platforms

2009-02-08T18:48:57+00:00

For historical reason, this driver used its own saving/restoring of the PCI config space, and used the state of it on resume as an indication as to whether it needed to re-POST the chip or not. This methods breaks with the later core changes since the core will have restored things for us. This patch fixes it by removing that custom code, using standard core methods to save/restore state, and testing for the need to re-POST by comparing the content of a few key PLL registers.

aty128fb: Properly save PCI state before changing PCI PM level

2009-02-08T18:48:56+00:00

This fixes aty128fb to properly save the PCI config space -before- it potentially switches the PM state of the chip. This avoids a warning with the new PM core and is the right thing to do anyway. I also replaced the hand-coded switch to D2 with a call to the genericc pci_set_power_state() and removed the code that switches it back to D0 since the generic code is doing that for us nowadays.

atyfb: Properly save PCI state before changing PCI PM level

2009-02-08T18:48:56+00:00

This fixes atyfb to properly save the PCI config space -before- it potentially switches the PM state of the chip. This avoids a warning with the new PM core and is the right thing to do anyway. I also slightly cleaned up the code that checks whether we are running on a PowerMac to do a runtime check instead of a compile check only, and replaced a deprecated number with the proper symbolic constant. Finally, I removed the useless switch to D0 from resume since the core does it for us. Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Linus Torvalds

async: use list_move_tail

2009-02-08T18:00:26+00:00

list.h provides a dedicated primitive for "list_del followed by list_add_tail"... list_move_tail. Signed-off-by: Arjan van de Ven Signed-off-by: Stefan Richter

async: Rename _special -> _domain for clarity.

2009-02-08T17:56:11+00:00

Rename the async_*_special() functions to async_*_domain(), which describes the purpose of these functions much better. [Broke up long lines to silence checkpatch] Signed-off-by: Cornelia Huck Signed-off-by: Arjan van de Ven

async: Add some documentation.

2009-02-08T17:56:11+00:00

Add some kerneldoc to the async interface. Signed-off-by: Cornelia Huck Signed-off-by: Arjan van de Ven

async: Handle kthread_run() return codes.

2009-02-08T17:56:10+00:00

If we fail to create the manager thread, fall back to non-fastboot. If we fail to create an async thread, try again after waiting for a bit. Signed-off-by: Cornelia Huck Signed-off-by: Arjan van de Ven

async: Fix running list handling.

2009-02-08T17:56:10+00:00

async_schedule() should pass in async_running as the running list, and run_one_entry() should put the entry to be run on the provided running list instead of always on the generic one. Reported-by: Jonathan Corbet Signed-off-by: Cornelia Huck Signed-off-by: Arjan van de Ven
