2014-04-08hw/pci-host/prep: Don't reverse IO accesses on bigendian hostsPeter Maydell1-4/+4
The raven_io_read() and raven_io_write() functions pass and return values in little-endian format (since the IO op struct is marked DEVICE_LITTLE_ENDIAN); however they were storing the values in the buffer to pass to address_space_read/write() in host-endian order, which meant that on big-endian hosts the values were inadvertently reversed. Use the *_le_p() accessors instead so that we are consistent regardless of host endianness. Strictly speaking the byte order of the buffer for address_space_rw() is target byte order (which for PPC will be BE) but it doesn't actually matter as long as we are consistent about the marking on the IO op struct and which stl_*_p(). This bug was probably introduced due to confusion caused by the two different versions of ldl_p() and friends: bswap.h defines versions meaning "host endianness access" cpu-all.h defines versions meaning "target endianness access" As a target-independent source file prep.c gets the bswap.h versions; the very similar looking code in ioport.c is compiled per-target and gets the cpu-all.h versions.

2014-04-08gtk: Implement grab-on-click behavior in relative modeTakashi Iwai1-2/+17
This patch changes the behavior in the relative mode to be compatible with other UIs, namely, grabbing the input at the first left click. It improves the usability a lot; otherwise you have to press ctl-alt-G or select from menu at each time you want to move the pointer. Also, the input grab is cleared when the current mode is switched to the absolute mode. The automatic reset of the implicit grabbing is needed since the switching to the absolute mode happens always after the click even on Gtk. That is, we cannot check whether the absolute mode is already available at the first click time even though it should have been switched in X11 input driver side.

2014-04-08PPC: Clean up DECR implementationAlexander Graf4-30/+71
There are 3 different variants of the decrementor for BookE and BookS. The BookE variant sets TSR[DIS] to 1 when the DEC value becomes 1 or 0. TSR[DIS] is then the indicator whether the decrementor interrupt line is asserted or not. The old BookS variant treats DEC as an edge interrupt that gets triggered when the DEC value's top bit turns 1 from 0. The new BookS variant maintains the assertion bit inside DEC itself. Whenever the DEC value becomes negative (top bit set) the DEC interrupt line is asserted. So far we implemented mostly the old BookS variant. Let's do them all properly. This fixes booting pseries ppc64 guest images in TCG mode for me. Signed-off-by: Alexander Graf <agraf@suse.de>

2014-04-08target-ppc: Correct Simple VSR LE Host InversionsTom Musta1-190/+190
A common pattern in the VSX helper code macros is the use of "x.fld[i]" where "x" is a VSR and "fld" is an argument to a macro ("f64" or "f32" is passed). This is not always correct on LE hosts. This change addresses all instances of this pattern to be "x.fld" where "fld" is: - "VsrD(0)" for scalar instructions accessing 64-bit numbers - "VsrD(i)" for vector instructions accessing 64-bit numbers - "VsrW(i)" for vector instructions accessing 32-bit numbers Note that there are no instances of this pattern where a scalar instruction accesses a 32-bit number. Note also that it would be correct to use "VsrD(i)" for scalar instructions since the loop index is only ever "0". I have choosen to use "VsrD(0)" instead ... it seems a little clearer.

The relative pointer tracking mode was still buggy even after the previous fix of the motion-notify-event since the events are filtered out when the pointer moves outside the drawing window due to the boundary check for the absolute mode. This patch fixes the issue by moving the unnecessary boundary check into the if block of absolute mode, and keep the coordinate in the relative mode even if it's outside the drawing area. But this makes the coordinate (last_x, last_y) possibly pointing to (-1,-1), introduce a new flag to indicate the last coordinate has been updated.

2014-04-04dataplane: replace iothread object_add() with embedded instanceStefan Hajnoczi1-19/+12
Before IOThread was its own object, each virtio-blk device would create its own internal thread. We need to preserve this behavior for backwards compatibility when users do not specify -device virtio-blk-pci,iothread=<id>. This patch changes how the internal IOThread object is created. Previously we used the monitor object_add() function, which is really a layering violation. The problem is that this needs to assign a name but we don't have a name for this internal object. Generating names for internal objects is a pain but even worse is that they may collide with user-defined names. Paolo Bonzini <pbonzini@redhat.com> suggested that the internal IOThread object should not be named. This way the conflict cannot happen and we no longer need object_add(). One gotcha is that internal IOThread objects will not be listed by the query-iothreads command since they are not named. This is okay though because query-iothreads is new and the internal IOThread is just for backwards compatibility. New users should explicitly define IOThread objects.

2014-04-04block: Fix snapshot=on for protocol parsed from filenameKevin Wolf4-70/+115
Since commit 9fd3171a, BDRV_O_SNAPSHOT uses an option QDict to specify the originally requested image as the backing file of the newly created temporary snapshot. This means that the filename is stored in "file.filename", which is an option that is not parsed for protocol names. Therefore things like -drive file=nbd:localhost:10809 were broken because it looked for a local file with the literal name 'nbd:localhost:10809'. This patch changes the way BDRV_O_SNAPSHOT works once again. We now open the originally requested image as normal, and then do a similar operation as for live snapshots to put the temporary snapshot on top. This way, both driver specific options and parsed filenames work. As a nice side effect, this results in code movement to factor bdrv_append_temp_snapshot() out. This is a good preparation for moving its call to drive_init() and friends eventually. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Reviewed-by: Max Reitz <mreitz@redhat.com>
2014-04-04cpu-exec: Unlock tb_lock if we longjmp out of code generationPeter Maydell1-0/+8
If the guest attempts to execute from unreadable memory, this will cause us to longjmp back to the main loop from inside the target frontend decoder. For linux-user mode, this means we will still hold the tb_ctx.tb_lock, and will deadlock when we try to start executing code again. Unlock the lock in the return-from-longjmp code path to avoid this.

2014-04-04page_check_range: don't bail out early after unprotecting pageAndrei Warkentin1-1/+0
When checking a page range, if we found that a page was made read-only by QEMU because it contained translated code, we were incorrectly returning immediately after unprotecting that page, rather than continuing to check the entire range, so we might fail to unprotect pages later in the range, or might incorrectly return a "success" result even if later pages were not writable. In particular, this could cause segfaults in a case where signals are delivered back to back on a target architecture which uses trampoline code in the stack frame (as AArch64 currently does). The second signal causes a segfault because the frame cannot be written to (it was protected because we translated and executed the restorer trampoline, and the unprotect logic did not unprotect the whole range).

2014-04-04hw/arm/vexpress, hw/arm/highbank: Don't insist that CPU has reset-cbar propertyPeter Maydell2-11/+10
For the machine models which can have a Cortex-A15 CPU (vexpress-a15 and midway), silently continue if the CPU object has no reset-cbar property rather than failing. This allows these boards to be used under KVM with the "-cpu host" option, since the 'host' CPU object has no reset-cbar property.

qemu doesn't print these CRs any more. The test still didn't fail because the output comparison ignores line endings, but the change turns up each time when you want to update the output. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Reviewed-by: Max Reitz <mreitz@redhat.com>
2014-04-04block: Don't parse 'filename' optionKevin Wolf3-4/+19
When using the QDict option 'filename', it is supposed to be interpreted literally. The code did correctly avoid guessing the protocol from any string before the first colon, but it still called bdrv_parse_filename() which would, for example, incorrectly remove a 'file:' prefix in the raw-posix driver.
