2012-02-02PPC: booke: add tlbnps handlingAlexander Graf
When using MAV 2.0 TLB registers, we have another range of TLB registers available to read the supported page sizes from. Add SPR definitions for those and add a helper function that we can use to receive such a bitmap even when using MAV 1.0. Signed-off-by: Alexander Graf <agraf@suse.de>
2012-02-02PPC: booke206: allow NULL raddr in ppcmas_tlb_checkAlexander Graf
We might want to call the tlb check function without actually caring about the real address resolution. Check if we really should write the value back. Signed-off-by: Alexander Graf <agraf@suse.de>
2012-02-02PPC: rename msync to msync_4xxAlexander Graf
The msync instruction as defined today is only valid on 4xx cores, not on e500 which also supports msync, but treats it the same way as sync. Rename it to reflect that it's 4xx only. Signed-off-by: Alexander Graf <agraf@suse.de>
2012-02-02PPC: e500: msync is 440 only, e500 has real syncAlexander Graf
The e500 CPUs don't use 440's msync which falls on the same opcode IDs, but instead use the real powerpc sync instruction. This is important, since the invalid mask differs between the two. Signed-off-by: Alexander Graf <agraf@suse.de>
2012-02-02PPC: e500mc: add missing IVORs to bitmapAlexander Graf
E500mc supports IVORs 36-41. Add them to the support mask. Drop SPE support too. Signed-off-by: Alexander Graf <agraf@suse.de>
2012-02-02PPC: Add IVOR 38-42Alexander Graf
Our code only knows IVORs up to 37. Add the new ones defined in ISA 2.06 from 38 - 42. Signed-off-by: Alexander Graf <agraf@suse.de> Reviewed-by: Andreas Färber <afaerber@suse.de>
2012-02-02PPC: KVM: Update HIOR code to new interfaceAlexander Graf
Unfortunately the HIOR setting code slipped into upstream QEMU before it was pulled into upstream KVM. And since Murphy is always right, comments on the patches only emerged on the pull request leading to changes in the interface. So here's an update to the HIOR setting. While at it, I also relaxed it a bit since for HV KVM we can already run fine without and 3.2 works just fine with HV KVM but when not setting HIOR. We will only need this when running PAPR in PR KVM. Since we accidently changed the ABI and API along the way, we have to update the underlying kernel headers together with the code that uses it to not break bisectability. Signed-off-by: Alexander Graf <agraf@suse.de>
2012-02-02KVM: Update headers (except HIOR mess)Alexander Graf
This patch is basically what ./scripts/update-linux-headers.sh against upstream KVM's next branch outputs except that all the HIOR bits are removed. These we have to update with the code that uses them. Signed-off-by: Alexander Graf <agraf@suse.de>
2012-02-01main-loop: For tools, initialize timers as part of qemu_init_main_loop()Michael Roth
In some cases initializing the alarm timers can lead to non-negligable overhead from programs that link against qemu-tool.o. At least, setting a max-resolution WinMM alarm timer via mm_start_timer() (the current default for Windows) can increase the "tick rate" on Windows OSs and affect frequency scaling, and in the case of tools that run in guest OSs such has qemu-ga, the impact can be fairly dramatic (+20%/20% user/sys time on a core 2 processor was observed from an idle Windows XP guest). This patch doesn't address the issue directly (not sure what a good solution would be for Windows, or what other situations it might be noticeable), but it at least limits the scope of the issue to programs that "opt-in" to using the main-loop.c functions by only enabling alarm timers when qemu_init_main_loop() is called, which is already required to make use of those facilities, so existing users shouldn't be affected.

2012-02-01main-loop: Fix SetEvent() on uninitialized handle on win32Michael Roth
The __attribute__((constructor)) init_main_loop() automatically get called if qemu-tool.o is linked in. On win32, this leads to a qemu_notify_event() call which attempts to SetEvent() on a HANDLE that won't be initialized until qemu_init_main_loop() is manually called, breaking qemu-tools.o programs on Windows at runtime. This patch checks for an initialized event handle before attempting to set it, which is analoguous to how we deal with an unitialized io_thread_fd in the posix implementation.

2012-02-01sdl: Limit sdl_grab_end in handle_activation to Windows hostsJan Kiszka
There are scenarios on Linux with some SDL versions where handle_activation is continuous invoked with state = SDL_APPINPUTFOCUS and gain = 0 while we grabbed the input. This causes a ping-pong when we grab the input after an absolute mouse entered the window. As this sdl_grab_end was once introduced to work around a Windows-only issue (0294ffb9c8), limit it to that platform.

2012-02-01sdl: Grab input on end of non-absolute mouse clickJan Kiszka
By grabbing the input already on button down, we leave the button in that state for the host GUI. Thus it takes another click after releasing the input again to synchronize the mouse button state. Avoid this by grabbing on button up. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-02-01Revert "Handle SDL grabs failing (Mark McLoughlin)"Jan Kiszka
This reverts commit 6bb816031f8bc0aafc3476e6dfa4293ee3a5f106. SDL_WM_GrabInput does not reliably bail out if grabbing is impossible. So if we get here, we already lost and will block. But this can no longer happen due to the check in sdl_grab_start. So this patch became obsolete.

2012-02-01sdl: Fix block prevention of SDL_WM_GrabInputJan Kiszka
Consistently check for SDL_APPINPUTFOCUS before trying to grab the input focus. Just checking for SDL_APPACTIVE doesn't work. Moving the check to sdl_grab_start allows for some consolidation. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2012-02-01qdev: Introduce lost tick policy propertyJan Kiszka
Potentially tick-generating timer devices will gain a common property: lock_tick_policy. It allows to encode 4 different ways how to deal with tick events the guest did not process in time: discard - ignore lost ticks (e.g. if the guest compensates for them already) delay - replay all lost ticks in a row once the guest accepts them again merge - if multiple ticks are lost, all of them are merged into one which is replayed once the guest accepts it again slew - lost ticks are gradually replayed at a higher frequency than the original tick Not all timer device will need to support all modes. However, all need to accept the configuration via this common property. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

Up to now, there was no special section for the different host operating systems used with QEMU. scripts/get_maintainer.pl did not show a maintainer for OS specific files and patches. Therefore I added three hosts systems: * POSIX for the majority of host systems which are supported. This includes BSD and Linux host systems. * LINUX is a special case of POSIX needed for some Linux specific files and directories. * W32, W64 for a well known family of closed source operating systems.
