2011-01-20pxa2xx_lcd: restore updating of displayDmitry Eremin-Solenikov
Recently PXA2xx lcd have stopped to be updated incrementally (picture frozen). This patch fixes that by passing non min/max x/y, but rather (correctly) x/y and w/h. Signed-off-by: Dmitry Eremin-Solenikov <dbaryshkov@gmail.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2011-01-20usb-hid: modifiers should generate an eventAurelien Jarno
When a modifier key is pressed or released, the USB HID keyboard still answers NAK, unless another key is also pressed or released. The patch fixes that by calling usb_hid_changed() when a modifier key is pressed or released. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2011-01-20softfloat: fix floatx80_is_{quiet,signaling}_nan()Aurelien Jarno
floatx80_is_{quiet,signaling}_nan() functions are incorrectly detecting the type of NaN, depending on SNAN_BIT_IS_ONE, one of the two is returning the correct value, and the other true for any kind of NaN. This patch fixes that by applying the same kind of comparison as for other float formats, but taking into account the explicit bit. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2011-01-18mips: Expire late timers when reading cp0_countEdgar E. Iglesias
When reading cp0_count from a timer with a late trigger that should already have expired, expire it and raise the timer irq. This makes it possible for guest code (e.g, Linux) that first read cp0_count, then compare it with cp0_compare and check for raised timer interrupt lines to run reliably.

2011-01-16USB keyboard emulation key mapping errorMichael Tokarev
The USB keyboard emulation's translation table in hw/usb-hid.c doesn't match the codes actually sent for the Logo (a.k.a. "Windows") or Menu keys. This results in the guest OS not being able to receive these keys at all when the USB keyboard emulation is being used. In particular, both the keymap in /usr/share/kvm/keymaps/modifiers and the evdev table in x_keymap.c map these keys to 0xdb, 0xdc, and 0xdd, while usb_hid_usage_keys[] seems to be expecting them to be mapped to 0x7d, 0x7e, and 0x7f. The attached patch seems to fix the problem, at least in my (limited) testing. http://bugs.debian.org/578846 http://bugs.debian.org/600593 (cloned from the above against different pkg) https://bugs.launchpad.net/qemu/+bug/584139 Signed-Off-By: Brad Jorsch <anomie@users.sourceforge.net> Signed-Off-By: Michael Tokarev <mjt@tls.msk.ru> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2011-01-16tcg/sparc64: fix segfaultBlue Swirl
With current OpenBSD, code_gen_buffer was mapped 8GB away from text segment. Then any helpers were beyond the 2GB range of call instruction genereated by TCG and so the calls would go nowhere, leading to a segfault. Fix by specifying an address for the code_gen_buffer, hopefully free and nearby the helpers. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2011-01-14make_device_config: Fix non-fatal error message with dash and other shellsStefan Weil
ORS=" " adds a blank to the name of the include file. Some shells (e.g. dash) don't accept input redirection (tr -d '\r' < $f) when $f ends with a blank, so they print an error message instead of reading pci.mak. This is a non-fatal error because pci.mak does not contain an include line. It was introduced by commit 5d6b423c5cd6f9dfac30959ff1d5c088996719c3. Using printf avoids adding a blank and is also supported by older awk versions (this solution was suggested by Paolo Bonzini, thank you).

The MAINTAINERS file was lacking entries concerning the TCG code, add them based on the git history. For the common TCG code, is probably better to keep qemu-devel@non-gnu.org as this code can break easily, so it's better to get it reviewed by a few persons.

2011-01-14linux-user: ARM: clear the IT bits when invoking a signal handlerPeter Maydell
When invoking a signal handler for an ARM target, make sure the IT bits in the CPSR are cleared. (This would otherwise cause incorrect execution if the IT state was non-zero when an exception occured. This bug has been masked previously because we weren't getting the IT state bits at exception entry right anyway.) Also use the proper cpsr_read()/cpsr_write() interface to update the CPSR rather than manipulating CPUState fields directly.

2011-01-14target-arm: Remove redundant setting of IT bits before Thumb SWIPeter Maydell
Remove a redundant call to gen_set_condexec() in the translation of Thumb mode SWI. (SWI and WFI generate "exceptions" which happen after the execution of the instruction, ie when PC and IT bits have updated. So the condexec bits at this point are not correct. However, the code that handles finishing the translation of the TB will write the correct value of the condexec bits later, so the only effect was that a conditional Thumb SWI would generate slightly worse code than necessary.)
