I have tested it on OLPC XO-1.75 (MMP2 aka Armada610) and OLPC XO-4 (MMP3 aka PXA2128). After a bit of fighting, I have it running. Could you share your X driver, or your methodology for testing hardware cursors? I'd like to test your work there too.
BTW... a point on this. As you don't have the LCD_SPU_ADV_REG register, you probably don't have support for ARGB cursors. DRM only supports ARGB cursors. You can't down-convert an ARGB cursor to something which looks reasonable in the kernel, so I'd suggest forgetting hardware cursors. Even converting ARGB to transparency + RGB looks rubbish and wrong.
Interesting. Yes, a previous developer battled unsuccessfully with hardware cursors and in the end we ended up using low color depth ones which don't look great. I was wondering if you had found something new, but it sounds like that we really are limited by the hardware.
Thanks Daniel
