2013-02-21Remove elderly top level TODO filePeter Maydell
The top level TODO file hasn't been touched since 2008, so it's now an unhelpful and out of date mix of things that have already been done, things that don't make sense any more and things which could in theory be done but are not in practice important enough (or we'd have done them some time in the last five years). Remove it. The bug tracking system is probably a better place to track TODO items if we want to do so.

2013-02-21aio: support G_IO_HUP and G_IO_ERRStefan Hajnoczi
aio-posix.c could not take advantage of G_IO_HUP and G_IO_ERR because select(2) does not have equivalent events. Now that g_poll(3) is used we can support G_IO_HUP and G_IO_ERR.

2013-02-21aio: convert aio_poll() to g_poll(3)Stefan Hajnoczi
AioHandler already has a GPollFD so we can directly use its events/revents. Add the int pollfds_idx field to AioContext so we can map g_poll(3) results back to AioHandlers. Reuse aio_dispatch() to invoke handlers after g_poll(3).

2013-02-21aio: extract aio_dispatch() from aio_poll()Stefan Hajnoczi
We will need to loop over AioHandlers calling ->io_read()/->io_write() when aio_poll() is converted from select(2) to g_poll(2). Luckily the code for this already exists, extract it into the new aio_dispatch() function. Two small changes: * aio_poll() checks !node->deleted to avoid calling handlers that have been deleted. * Fix typo 'then' -> 'them' in aio_poll() comment.

2013-02-21slirp: switch to GPollFDStefan Hajnoczi
Slirp uses rfds/wfds/xfds more extensively than other QEMU components. The rarely-used out-of-band TCP data feature is used. That means we need the full table of select(2) to g_poll(3) events: rfds -> G_IO_IN | G_IO_HUP | G_IO_ERR wfds -> G_IO_OUT | G_IO_ERR xfds -> G_IO_PRI I came up with this table by looking at Linux fs/select.c which maps select(2) to poll(2) internally. Another detail to watch out for are the global variables that reference rfds/wfds/xfds during slirp_select_poll(). sofcantrcvmore() and sofcantsendmore() use these globals to clear fd_set bits. When sofcantrcvmore() is called, the wfds bit is cleared so that the write handler will no longer be run for this iteration of the event loop. This actually seems buggy to me since TCP connections can be half-closed and we'd still want to handle data in half-duplex fashion. I think the real intention is to avoid running the read/write handler when the socket has been fully closed. This is indicated with the SS_NOFDREF state bit so we now check for it before invoking the TCP write handler. Note that UDP/ICMP code paths don't care because they are connectionless. Note that slirp/ has a lot of tabs and sometimes mixed tabs with spaces. I followed the style of the surrounding code.

2013-02-21main-loop: switch to g_poll() on POSIX hostsStefan Hajnoczi
Use g_poll(3) instead of select(2). Well, this is kind of a cheat. It's true that we're now using g_poll(3) on POSIX hosts but the *_fill() and *_poll() functions are still using rfds/wfds/xfds. We've set the scene to start converting *_fill() and *_poll() functions step-by-step until no more rfds/wfds/xfds users remain. Then we'll drop the temporary gpollfds_from_select() and gpollfds_to_select() functions and be left with native g_poll(2). On Windows things are a little crazy: convert from rfds/wfds/xfds to GPollFDs, back to rfds/wfds/xfds, call select(2), rfds/wfds/xfds back to GPollFDs, and finally back to rfds/wfds/xfds again. This is only temporary and keeps the Windows build working through the following patches. We'll drop this excessive conversion later and be left with a single GPollFDs -> select(2) -> GPollFDs sequence that allows Windows to use select(2) while the rest of QEMU only knows about GPollFD.

I was trying to launch a PowerPC "bamboo" machine with more than 256MB of RAM with qemu-system-ppc -M bamboo -kernel $kernel -initrd $ramdisk -m 512, but QEMU would just hang. However, when I used -m 256, the machine would boot. I looked through the code in hw/ and it seems there is an error when the RAM memory is setup (if my understanding is correct).
