I think I will consider it finished when I can run PalmOS 5.0 on it. Linux works absolutely fine, but PalmOS boots only halfway through and gets stuck in some loop (probably not the OMAP emulation fault, probably one of the peripheral chips, which are also emulated). Running a closed-source OS is a real stress-test for an emulator. I don't think it is considered for inclusion. Before it is merged I would like to separate the generic OMAP code from board-related code (the board I emulate is the Palm Tunsgten|E handheld), but I imagine the QEMU maintainers won't like the way code is formatted and probably many other things, hard to say. If you want to emulate a different OMAP processor you'll probably want to add the emulation of the DSP part, which 310 doesn't have and it may a whole lot of additional work.

I really hoped to get response from QEMU author/ARM emulation maintainer regarding these points. Paul, any comments? Would you be interested to add more CPUs/boards? Any suggestion regarding this? Maybe if it is expected that there may be many implementation and they won't fit into core distribution, to provide API for plugin development? > If you want to emulate a different OMAP processor you'll probably want > to add the emulation of the DSP part, which 310 doesn't have and it > may a whole lot of additional work. Actually, I'm also working on porting a PDA to run Linux (iPaq 4150/XScale). So far I don't have strong need to run kernel compiled specifically for that device in QEMU, though SD support you implemented seems like very good addition for emulation of any PDA device. Anyway, I'm currently using Integrator/CP kernel from here: http://www.o-hand.com/~richard/qemu.html , which boots h4000 userland (Familiar Linux GPE) just fine. Well, that GPE image doesn't have suport for mouse, and QEMU cannot emulate touchscreen. So, first thing I'd be interested from your patch is that "absolute mouse" support. 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.

However, unless I have some personal/commercial interest in that particular board it's up to the patch author(s) to get that support into a state where I'm happy merging it. If the original author thinks it needs cleanup before submission I'm inclined to believe them ;-) All the normal guidelines for patch submission apply. i.e. follow coding conventions, split changes into logically separate patches, don't mix cleanups with new features, etc. Paul [1] As discussed previously on this list there are unresolved legal issues with emulating ARMv6/v7 cpus, however that's not relevant in this case. ^ permalink raw reply [flat|nested] 5+ messages in thread

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.
