2009-07-13target-ppc: enable PPC_MFTB for 44xBaojun Wang
According to PPC440 user manual, PPC 440 supports ``mftb'' even it's a preserved instruction: PPC440_UM2013.pdf, p.445, table A-3 when I compile a kernel (2.6.30, bamboo_defconfig/440EP & canyonlands/460EX), I can see ``mftb'' by using ppc-xxx-objdump vmlinux I have also checked the ppc 440x[456], 460S, 464, they also should support mftb. The following patch enable mftb for all ppc 440 variants, including: 440EP, 440GP, 440x4, 440x5 and 460 Signed-off-by: Baojun Wang <wangbj@gmail.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2009-07-12gdb-xml: fix hacks in powerpc register numberingNathan Froyd
The powerpc xml files contained a hack--an empty, non-existent register--for getting the register numbers to line up for newer (XML-aware) and older (non-XML-aware) GDB. While this hack worked in some cases, it didn't work in all cases, notably when the user used `finish' or `continue': GDB would attempt to read the non-existent register and QEMU would complain. This patch fixes things up properly. Instead of inserting a fake register, we explicitly declare the floating-point and SPE registers to start at 71. This action accomplishes the same thing as the nasty hack, except that now GDB never tries to fetch the non-existant register 70.

2009-07-12target-ppc: fix evmergelo and evmergelohiNathan Froyd
For 32-bit PPC targets, we translated: evmergelo rX, rX, rY as: rX-lo = rY-lo rX-hi = rX-lo which is wrong, because we should be transferring rX-lo first. This problem is fixed by swapping the order in which we write the parts of rX. Similarly, we translated: evmergelohi rX, rX, rY as: rX-lo = rY-hi rX-hi = rX-lo In this case, we can't swap the assignment statements, because that would just cause problems for: evmergelohi rX, rY, rX Instead, we detect the first case and save rX-lo in a temporary variable: tmp = rX-lo rX-lo = rY-hi rX-hi = tmp These problems don't occur on PPC64 targets because we don't split the SPE registers into hi/lo parts for such targets.

Commit 6a7ad299 ("Call qemu_bh_delete at bdrv_aio_bh_cb") deletes emulated aio bottom halves to prevent endless accumulation. However, it leaves a stale ->bh pointer, which is then waited on when the aio is reused. Zeroing the pointer fixes the issue, allowing vmdk format images to be used.

Contrary to what one could expect, the size of L1 tables is not cluster aligned.

2009-07-10Prefer sysfs for USB host devicesMark McLoughlin
Scanning for devices via /sys/bus/usb/devices/ and using them via the /dev/bus/usb/<bus>/<device> character devices is the prefered method on modern kernels, so try that first. When using SELinux and libvirt, qemu will have access to /sys/bus/usb but not /proc/bus/usb, so although the current code will work just fine, it will generate SELinux AVC warnings.
