So far I don't have strong need to run kernel compiled Ah, now I know, I've seen your commits on handhelds.org! There is a person working on PXA (I think 270) emulation in QEMU, but I think they're at implementing the CPU now and out of the other hardware there's only the serial port, but I don't know the details. I only remember the person's nick on IRC. > specifically for that device in QEMU, though SD support you > implemented seems like very good addition for emulation of any PDA > device.

The absolute mouse support in my patch was basically stolen from Anthony Liguori's early Wacom tablet patch. There are links to this patch in list archives, I'm not sure if it's integrated into QEMU yet, but there's a pointing device using absolute coordintates known as usb-tablet which is in the mainline already. I've been running GPE in QEMU as well, using mostly unmodified fs images from familiar.handhelds.org and SD emulation which you mentioned (IIRC I had to disable udev everytime). I took some screenshots which can be seen at http://zabor.org/balrog/palmte/ (filenames ending in "-emulator"). > Its status is also not clear - googling gives lots of references, and > over good period of time, but it seems that patch is still not in the > mainline? > > Well, I guess I need to look closer at you patch and try do my > builds based on it, before asking specific questions. > > > Also, my current tree is based on QEMU 0.8.0. > > Thanks, > > -- > Paul mailto:pmiscml@gmail.com > > Good luck with your port.
