Many of these should be cleaned up with proper qdev-/QOM-ification. Right now there are many catch-all headers in include/hw/ARCH depending on cpu.h, and this makes it necessary to compile these files per-target. However, fixing this does not belong in these patches.

The char-flow refactoring introduced a busy-wait that depended on an action from the VCPU thread. However, the VCPU thread could never take that action because the busy-wait starved the VCPU thread of the BQL because it never dropped the mutex while running select. Paolo doesn't want to drop this optimization for fear that we will stop detecting these busy waits. I'm afraid to keep this optimization even with the busy-wait fixed because I think a similar problem can occur just with heavy I/O thread load manifesting itself as VCPU pauses. As a compromise, introduce an artificial timeout after a thousand iterations but print a rate limited warning when this happens. This let's us still detect when this condition occurs without it being a fatal error.

The character backend refactoring introduced an undesirable busy wait. The busy wait happens if can_read returns zero and there is data available on the character device's file descriptor. Then, the I/O watch will fire continuously and, with TCG, the CPU thread will never run. 1) Char backend asks front end if it can write 2) Front end says no 3) poll() finds the char backend's descriptor is available 4) Goto (1) What we really want is this (note that step 3 avoids the busy wait): 1) Char backend asks front end if it can write 2) Front end says no 3) poll() goes on without char backend's descriptor 4) Goto (1) until qemu_chr_accept_input() called 5) Char backend asks front end if it can write 6) Front end says yes 7) poll() finds the char backend's descriptor is available 8) Backend handler called After this patch, the IOWatchPoll source and the watch source are separated. The IOWatchPoll is simply a hook that runs during the prepare phase on each main loop iteration. The hook adds/removes the actual source depending on the return value from can_read. A simple reproducer is qemu-system-i386 -serial mon:stdio ... followed by banging on the terminal as much as you can. :) Without this patch, emulation will hang.

It ignored the error code, and at least the 'goto fail' is obvious nonsense as it creates an endless loop (if the next attempt doesn't magically succeed) and leaves the in-memory L1 table in big-endian instead of converting it back. In error cases, there's no point in writing an updated L1 table, so skip this part for them. Signed-off-by: NKevin Wolf <kwolf@redhat.com>
