2011-10-16i8259: Convert to qdevJan Kiszka1-57/+100
This key cleanup step requires to move the IRQ debugging bit from i8259_set_irq directly to the per-PIC pic_set_irq, to pass the PIC parameters (I/O base, ELCR address and mask, master/slave mode) as qdev properties, and to interconnect the PICs with their environment via GPIO pins.

2011-10-16i8259: Eliminate PicState2Jan Kiszka2-35/+34
Introduce a reference to the slave PIC for the few cases we need to access it without a proper pointer at hand and drop PicState2. We could even live without slave_pic if we had a better way of modeling the cascade bus the PICs are attached to (in addition to the ISA bus).

2011-10-16i8259: Replace PicState::pics_state with master flagJan Kiszka1-9/+9
This reflects how real PICs indentify their role (in non-buffered mode): Pass the state of the /SP input on pic_init and use it instead of pics_state to differentiate between master and slave mode. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-10-16i8259: PREP: Replace pic_intack_read with pic_read_irqJan Kiszka3-41/+1
There is nothing in the i8259 spec that justifies the special pic_intack_read. At least the Linux PREP kernels configure the PICs properly so that pic_read_irq returns identical values, and setting read_reg_select in PIC0 cannot be derived from any special i8259 mode. So switch ppc_prep to pic_read_irq and drop the now unused PIC code.

2011-10-16i8259: Fix poll commandJan Kiszka1-1/+7
This was probably never used so far: According to the spec, polling means ack'ing the pending IRQ and setting its corresponding bit in isr. Moreover, we have to signal a pending IRQ via bit 7 of the returned value, and we must not return a spurious IRQ if none is pending. This implements the poll command without the help of pic_poll_read which is left untouched as pic_intack_read is still using it.

2011-10-16i8259: Switch to per-PIC IRQ updateJan Kiszka1-40/+21
This converts pic_update_irq to work against a single PIC instead of the complete cascade. Along this change, the required update after pic_set_irq1 is now moved into that function. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-10-16i8259: Clear ELCR on resetJan Kiszka1-5/+10
The ELCR is actually part of the chipset but we model it here for simplicity reasons. The PIIX3 clears the ELCR on reset, which was once broken by 4dbe19e181. Fix this by splitting up pic_init_reset from pic_reset and clearing the register in the latter. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-10-16i8259: Update IRQ state after resetJan Kiszka1-2/+1
MIPS and PPC users of the i8259 output signal expect us to report state updates also after reset. As no consumer (including the master PIC) can misinterpret the deassert as an activation event, it is safe to simply update the IRQ state after reset.

2011-10-16i8259: Reorder intack in pic_read_irqJan Kiszka1-4/+6
As we want to move the IRQ update to pic_intack, ordering matters: the slave ack must be executed before the master ack to avoid missing further pending slave IRQs. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-10-16i8259: Do not update IRQ output after spurious pic_poll_readJan Kiszka1-1/+0
If pic_poll_read finds no pending IRQ and return a spurious one instead, no PIC state is changed, thus we do not need to call pic_update_irq. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-10-16i8239: Introduce per-PIC output interruptJan Kiszka1-9/+12
As a first step towards more generic master-slave support, remove parent_irq in favor of a per-PIC output interrupt line.

2011-10-16pc: Fix and clean up PIC-to-APIC IRQ pathJan Kiszka4-12/+12
The master PIC is connected to the LINTIN0 of the APICs. As the APIC currently does not track the state of that line, we have to ask the PIC to reinject its IRQ after the CPU picked up an event from the APIC. This introduces pic_get_output to read the master PIC IRQ line state without changing it. The APIC uses this function to decide if a PIC IRQ should be reinjected on apic_update_irq. This reflects better how the real hardware works. The patch fixes some failures of the kvm unit tests apic and eventinj by allowing to enable the proper CPU IRQ deassertion when the guest masks some pending IRQs at PIC level.

2011-10-16pc: Generalize ISA IRQs to GSIsJan Kiszka5-31/+42
The ISA bus IRQ range is 0..15. What isa_irq_handler and IsaIrqState are actually dealing with are the Global System Interrupts. Refactor the code to clarify this. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-10-16pc: Drop useless test from isa_irq_handlerJan Kiszka1-3/+2
IsaIrqState::ioapic is always non-NULL. Probably, the concrete qemu_irq was supposed to be tested, but that's already done by qemu_set_irq. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
