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: NJan Kiszka <jan.kiszka@siemens.com> Signed-off-by: NBlue Swirl <blauwirbel@gmail.com>

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.

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.

There is absolutely no need to call reset functions when initializing devices. Since we are already registering them, calling qemu_system_reset() should suffice. Actually, it is what happens when we reboot the machine, and using the same process instead of a special case semantics will even allow us to find bugs easier. Furthermore, the fact that we initialize things like the cpu quite early, leads to the need to introduce synchronization stuff like qemu_system_cond. This patch removes it entirely. All we need to do is call qemu_system_reset() only when we're already sure the system is up and running I tested it with qemu (with and without io-thread) and qemu-kvm, and it seems to be doing okay - although qemu-kvm uses a slightly different patch. [ v2: user mode still needs cpu_reset, so put it in ifdef. ] [ v3: leave qemu_system_cond for now. ] Signed-off-by: NGlauber Costa <glommer@redhat.com> Signed-off-by: NBlue Swirl <blauwirbel@gmail.com>

In the very least, a change like this requires discussion on the list. The naming convention is goofy and it causes a massive merge problem. Something like this _must_ be presented on the list first so people can provide input and cope with it. This reverts commit 99a0949b. Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

This patch addresses the problems found by Andriy Gapon: - The code was incorrectly overwriting the high order 32 bits of the timer and hpet config registers. This didn't show up in testing because linux and windows use hpet in legacy mode, where the high order 32 bits (advertising available interrupts) of the timer config register are ignored, and the high order 32 bits of the hpet config register are reserved and unused. - The mask for level-triggered interrupts was off by a bit. (hpet doesn't currently support level-triggered interrupts). In addition, I removed some unused #defines, and corrected the ioapic interrupt values advertised. I'd set this up early in hpet development and never went back to correct it, and no bugs resulted since linux and windows use hpet in legacy mode where available interrupts are ignored.

Add the parameter 'order' to qemu_register_reset and sort callbacks on registration. On system reset, callbacks with lower order will be invoked before those with higher order. Update all existing users to the standard order 0. Note: At least for x86, the existing users seem to assume that handlers are called in their registration order. Therefore, the patch preserves this property. If someone feels bored, (s)he could try to identify this dependency and express it properly on callback registration.

While Intel's spec is not that clear here, latest changes to Linux' HPET code (commit c23e253e67c9d8a91a0ffa33c1f571a17f0a2403, "x86: hpet: stop HPET_COUNTER when programming periodic mode") strongly suggest that HPET_TN_SETVAL rather means: Set _both_ the comparator value and register. With this patch applied, I'm again able to boot 2.6.30-rc kernels as they no longer panic like this (which was due to the comparator register remaining 0): ENABLING IO-APIC IRQs ..TIMER: vector=0x30 apic1=0 pin1=2 apic2=-1 pin2=-1 ..MP-BIOS bug: 8254 timer not connected to IO-APIC ...trying to set up timer (IRQ0) through the 8259A ... .....

This patch adds HPET emulation. It can be disabled with -disable-hpet. An hpet provides a more finely granular clocksource than otherwise available on PC. This means that latency-dependent applications (e.g. multimedia) will generally be smoother when using the HPET.
