2010-06-13Move stdbool.hPaul Brook
Move inclusion of stdbool.h to common header files, instead of including in an ad-hoc manner. Signed-off-by: Paul Brook <paul@codesourcery.com>
2010-06-13hpet: Add MSI supportJan Kiszka
This implements the HPET capability of routing IRQs to the front-side bus, aka MSI support. This feature can be enabled via the qdev property "msi" and is off by default. Note that switching it on can cause guests (at least Linux) to use the HPET as timer instead of the LAPIC. KVM users should recall that only the latter is currently available as fast in-kernel model.

2010-06-13hpet: Make number of timers configurableJan Kiszka
One HPET block supports up to 32 timers. Allow to instantiate more than the recommended and implemented minimum of 3. The number is configured via the qdev property "timers". It is also saved/restored so that it need not match between migration peers. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2010-06-13hpet: Add support for level-triggered interruptsJan Kiszka
By implementing this feature we can also remove a nasty way to kill qemu (by trying to enable level-triggered hpet interrupts). Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2010-06-13hpet: Drop static stateJan Kiszka
Instead of keeping a static reference around, pass the state to hpet_enabled and hpet_get_ticks. All callers now have it at hand. Will once allow to instantiate the HPET more than a single time. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2010-06-13hpet/rtc: Rework RTC IRQ replacement by HPETJan Kiszka
Allow the intercept the RTC IRQ for the HPET legacy mode. Then push routing to IRQ8 completely into the HPET. This allows to turn hpet_in_legacy_mode() into a private function. Furthermore, this stops the RTC from clearing IRQ8 even if the HPET is in control. This patch comes with a side effect: The RTC timers will no longer be stoppend when there is no IRQ consumer, possibly causing a minor performance degration. But as the guest may want to redirect the RTC to the SCI in that mode, it should normally disable unused IRQ source anyway.

2010-06-13hpet: Start/stop timer when HPET_TN_ENABLE is modifiedJan Kiszka
We have to update the qemu timer when the per-timer enable bit is toggled, just like for HPET_CFG_ENABLE changes. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2010-06-13hpet: Convert to qdevJan Kiszka
Register the HPET as a sysbus device and create it that way. As it can route its IRQs to any ISA IRQ, we need to connect it to all 24 of them. Once converted to qdev, we can move reset handler and vmstate registration into its hands as well. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2010-06-13hpet: Move static timer field initializationJan Kiszka
Properly initialize HPETTimer::tn and HPETTimer::state once during hpet_init instead of (re-)writing them on every reset. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2010-06-13hpet: Silence warning on write to running main counterJan Kiszka
Setting the main counter while the HPET is enabled may not be a good idea of the guest, but it is supported and should, thus, not spam the host console with warnings. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2010-06-13hpet: Coding style cleanups and some refactoringsJan Kiszka
This moves the private HPET structures into the C module, simplifies some helper functions and fixes most coding style issues (biggest chunk was improper switch-case indention). No functional changes. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Reviewed-by: Juan Quintela <quintela@redhat.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2010-06-13hpet: Catch out-of-bounds timer accessJan Kiszka
Also prevent out-of-bounds write access to the timers but don't spam the host console if it triggers. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2010-06-04ide: Remove redundant IDEState member confMarkus Armbruster
Commit 428c149b added IDEState member conf to let commit 0009baf1 find the BlockConf from there. It exists only for qdev drives, created via ide_drive_initfn(), not for drives created via ide_init2(). But for a qdev drive, we can just as well reach its IDEDevice, which contains the BlockConf. Do that, and revert the parts of commit 428c149b that add IDEState member conf. Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

Previous commit added QMP documentation to the qemu-monitor.hx file, it's is a copy of this information. While it's good to keep it near code, maintaining two copies of the same information is too hard and has little benefit as we don't expect client writers to consult the code to find how to use a QMP command.

2010-05-31arm: fix arm kernel boot for non zero start addrLars Munch
Booting an arm kernel has been broken a while when booting from non zero start address. This is due to the order of events: board init loads the kernel and sets register 15 to the start address and then qemu_system_reset reset the cpu making register 15 zero again.
