2011-01-20sh_serial: process all received charactersAurelien Jarno
When operating on the SCIF, process all the received characters, as long as the FIFO can handle them. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2011-01-20sh_serial: remove one level of indirectionAurelien Jarno
The indirection functions are empty since commit 8da3ff180974732fc4272cb4433fef85c1822961. 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>

2011-01-20virtio-serial: save/restore new fields in port structAmit Shah
The new fields that got added as part of not copying over the guest buffer to the host need to be saved/restored across migration. Do that and bump up the version number. Signed-off-by: Amit Shah <amit.shah@redhat.com>
2011-01-20virtio-serial: Add support for flow controlAmit Shah
This commit lets apps signal an incomplete write. When that happens, stop sending out any more data to the app and wait for it to unthrottle the port. Signed-off-by: Amit Shah <amit.shah@redhat.com>
2011-01-20virtio-serial: Let virtio-serial-bus know if all data was consumedAmit Shah
The have_data() API to hand off guest data to apps using virtio-serial so far assumed all the data was consumed. Relax this assumption. Future commits will allow for incomplete writes. Signed-off-by: Amit Shah <amit.shah@redhat.com>
2011-01-20virtio-serial: Don't copy over guest buffer to hostAmit Shah
When the guest writes something to a host, we copied over the entire buffer first into the host and then processed it. Do away with that, it could result in a malicious guest causing a DoS on the host. Reported-by: Paul Brook <paul@codesourcery.com> Signed-off-by: Amit Shah <amit.shah@redhat.com>
2011-01-20virtio-serial: move out discard logic in a separate functionAmit Shah
Instead of combining flush logic into the discard case and not discard case, have one function doing discard case. This will help later when adding flow control logic to the do_flush_queued_data() function. Signed-off-by: Amit Shah <amit.shah@redhat.com>
2011-01-19microblaze: Add support for load/store reversedEdgar E. Iglesias

2011-01-19pci: fix device pathsMichael S. Tsirkin
Patch a6a7005d14b3c32d4864a718fb1cb19c789f58a5 generated broken device paths. We snprintf with a length shorter than the output, so the last character is discarded and replaced by the null byte. Fix it up by snprintf to a buffer which is larger by 1 byte and then memcpy the data (without the null byte) to where we need it. Reported-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

2011-01-19virtio-console: Factor out common init between console and generic portsAmit Shah
The initialisation for generic ports and console ports is similar. Factor out the parts that are the same in a different function that can be called from each of the initfns. Signed-off-by: Amit Shah <amit.shah@redhat.com>

2011-01-18mips: Break TBs after mfc0_countEdgar E. Iglesias
Break the TB after reading the count register. This makes it possible to take timer interrupts immediately after a read of a possibly expired timer. Signed-off-by: Edgar E. Iglesias <edgar.iglesias@gmail.com>
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.

2011-01-17sm501: add 2D engine copyrect supportAurelien Jarno
Linux kernel started to use the SM501 2D engine for the console, and especially the copyrect operation. Implement this operation so that recent kernels can be used with QEMU. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2011-01-17savevm: Fix no_migrateAlex Williamson
The no_migrate save state flag is currently only checked in the last phase of migration. This means that we potentially waste a lot of time and bandwidth with the live state handlers before we ever check the no_migrate flags. The error message printed when we catch a non-migratable device doesn't get printed for a detached migration. And, no_migrate does nothing to prevent an incoming migration to a target that includes a non-migratable device. This attempts to fix all of these. One notable difference in behavior is that an outgoing migration now checks for non-migratable devices before ever connecting to the target system. This means the target will remain listening rather than exit from failure. Signed-off-by: Alex Williamson <alex.williamson@redhat.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

2011-01-17acpi_piix4: expose no_hotplug attribute via i/o portMarcelo Tosatti
Expose no_hotplug attribute via I/O port, so ACPI BIOS can indicate removability status to guest OS.

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).

2011-01-14MAINTAINERS: add entries for TCGAurelien Jarno
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.
