|
* MC idling:
|
|
*
|
|
* For SetupFBLocation and Restore, we require a fully idle MC as we might lock up
|
|
* otherwise. Both calls now check whether the MC is Idle before attempting
|
|
* to set up the MC, and complain loudly when this fails.
|
|
*
|
|
* Likely suspect registers for when the Idle fails:
|
|
* DxVGA_CONTROL & D1VGA_MODE_ENABLE (run RHDVGADisable beforehand)
|
|
* DxCRTC_CONTROL & 0x1 (run DxCRTCDisable beforehand)
|
|
* (... Add more here...)
|
|
*
|
|
*
|
|
* MC addressing:
|
|
*
|
|
* On R600 and up the MC can use a larger than 32bit card internal address for
|
|
* its framebuffer. This is why the Address used inside the MC code is a
|
|
* CARD64.
|
|
*
|
|
* rhdPtr->FbIntAddress is kept as a CARD32 for the time being. This is still
|
|
* valid, as this makes the R500 code simpler, and since we pick FbIntAddress
|
|
* from a 32bit register anyway on R600. FbIntAddress will also correctly cast
|
|
* to a CARD64 when passed to the likes of the SetupFBLocation callback.
