2011-06-24w32: Remove redundant definitions of PRI*64Stefan Weil

2011-06-24configure: Don't create symlinks to nonexistent targetsPeter Maydell
When we create the symlinks to source tree files, don't create them if the file is not actually present in the source tree; this will happen if the file is in a git submodule that wasn't checked out. This also avoids the odd effect where an in-source-tree configure will end up creating the missing file as a symlink to itself.

2011-06-23coreaudio: Fix OSStatus format specifierAndreas Färber
OSStatus type is defined as SInt32. That's signed int on __LP64__ and signed long otherwise. Since it is an explicit 32-bit-width type, cast to corresponsing POSIX type and use PRId32 format specifier. This avoids a warning on ppc64.

coreaudioVoiceOut's audioDevicePropertyBufferFrameSize is defined as UInt32 and is being used by reference for AudioDevice{Get,Set}Property(). UInt32 is unsigned int on __LP64__ but unsigned long otherwise. Cast to POSIX type and use PRIu32 format specifier to hide the details. This avoids a warning on ppc64.

2011-06-23hw/usb-ohci.c: Fix handling of remote wakeup corner casesPeter Maydell
Correct a number of minor errors in the OHCI wakeup implementation: * when the port is suspended but the controller is not, raise RHSC * when the controller is suspended but the port is not, raise RD * when the controller is suspended, move it to resume state These fix some edge cases where a USB device might not successfully get the attention of the guest OS if it tried to do so at the wrong time.

2011-06-23usb-bus: Don't allow speed mismatch while attaching devicesHans de Goede
Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-06-23usb-linux: allow "compatible" high speed devices to connect at fullspeedHans de Goede
Some usb2 highspeed devices, like usb-msd devices, work fine when redirected to a usb1 virtual controller. Allow this to avoid the new speedhecks causing regressions for users who do not enable the new experimental ehci code. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-06-23usb: Add a speedmask to devicesHans de Goede
This is used to indicate at which speed[s] the device can operate, so that this can be checked to match the ports capabilities when it gets attached to a bus. Note that currently all usb1 emulated device claim to be fullspeed, this seems to not cause any problems, but still seems wrong, because with real hardware keyboards, mice and tablets usually are lo-speed, so reporting these as fullspeed devices seems wrong.

2011-06-23ehci: switch to nanosecondsGerd Hoffmann
Make ehci use nanoseconds everywhere. Simplifies time calculations. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-06-23ehci: add freq + maxframes propertiesGerd Hoffmann
Add properties for the wakeup rate and the max number of frames ehci will process at once. The wakeup rate defaults to 1000 which equals the usb frame rate. This can be reduced to make qemu wake up less often when ehci is active. In case the wakeup rate is reduced or the ehci timer is delayed due to latency issues elsewhere in qemu ehci will process multiple frames at once. The maxframes property specifies the upper limit for this. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-06-23usb-linux: track inflight iso urb countGerd Hoffmann
Track the number of iso urbs which are currently in flight. Log a message in case the count goes down to zero. Also warn in case many urbs are returned at the same time. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-06-23usb-linux: make iso urb count contigurableGerd Hoffmann
Add a qdev property for the number of iso urbs which usb-linux keeps in flight, so it can be configured at runtime. Make it default to four (old hardcoded value used to be three). Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2011-06-22target-arm: Fix BASEPRI, BASEPRI_MAX, and FAULTMASK accessSebastian Huber

2011-06-22target-arm: Minimal implementation of performance countersPeter Maydell
Newer Linux kernels assume the existence of the performance counter cp15 registers. Provide a minimal implementation of these registers. We support no events. This should be compliant with the ARM ARM, except that we don't implement the cycle counter. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2011-06-22Revert "Makefile.target: Allow target helpers to be in any *_helper.c file"Peter Maydell
Reverts commit 348883d4828d7434e1053407818598f7fb15e594, so the global env is no longer available to helper.c files other than op_helper.c. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2011-06-22Revert "target-arm: Use global env in neon_helper.c helpers"Peter Maydell
This effectively reverts commit 2a3f75b42ac255be09ec2939b96c549ec830efd3 so that we return to passing CPUState to helpers as an explicit parameter. (There were a number of conflicts in target-arm/translate.c which had to be resolved by hand so it is not a pure revert.) Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2011-06-22target-arm: Pass fp status pointer explicitly to neon fp helpersPeter Maydell
Make the Neon helpers for various floating point operations take an explicit pointer to the float_status they use, so they don't rely on the global environment pointer any more. This also allows us to drop the mul/sub/add helpers completely and just use the vfp versions. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2011-06-22target-arm: Make VFP binop helpers take pointer to fpstatus, not CPUStatePeter Maydell
Make the VFP binop helper functions take a pointer to the fp status, not the entire CPUState. This will allow us to use them for Neon operations too. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2011-06-22target-arm: Add helper function to generate code to get fpstatus pointerPeter Maydell
Add and use a helper function which returns a TCGv which is a pointer to the fp_status for either Neon or VFP operations. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2011-06-22Revert "target-arm: Use global env in iwmmxt_helper.c helpers"Peter Maydell

2011-06-22net: Warn about "-net nic" options which were ignoredPeter Maydell
Diagnose the case where the user asked for a NIC via "-net nic" but the board didn't instantiate that NIC (for example where the user asked for two NICs but the board only supports one). Note that this diagnostic doesn't apply to NICs created through -device, because those are always instantiated.

2011-06-22net: Don't warn about the default network setupPeter Maydell
Don't warn about the default network setup that you get if no command line -net options are specified. There are two cases that we would otherwise complain about: (1) board doesn't support a NIC but the implicit "-net nic" requested one (2) CONFIG_SLIRP not set, so the implicit "-net nic" sets up a nic that isn't connected to anything Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2011-06-22Revert "net: Improve the warnings for dubious command line option combinations"Peter Maydell
This reverts commit f68b9d672b90dedc79aeb9b44607f484dbe46a6b. That attempt at diagnosing unused -net nic options failed to account for NICs created via -device; back it out cleanly in preparation for implementing in a different manner.

2011-06-22Optimize screendumpAvi Kivity
When running kvm-autotest, fputc() is often the second highest (sometimes #1) function showing up in a profile. This is due to fputc() locking the file for every byte written.

2011-06-21linux-user: Fix sync_file_range on 32bit mipsRiku Voipio

2011-06-21linux-user/signal.c: Remove only-ever-set variable fpu_save_addrPeter Maydell
Move the access of fpu_save into the commented out skeleton code for restoring FPU registers on SPARC sigreturn, thus silencing a gcc 4.6 "variable set but never used" warning.

2011-06-21linux-user: Bump do_syscall() up to 8 syscall argumentsPeter Maydell
On 32 bit MIPS a few syscalls have 7 arguments, and so to call them via NR_syscall the guest needs to be able to pass 8 arguments to do_syscall(). Raise the number of arguments do_syscall() takes accordingly. This fixes some gcc 4.6 compiler warnings about arg7 and arg8 variables being set and never used.
