Although migrate_fd_put_buffer() sets MIG_STATE_ERROR if it failed, since migrate_fd_put_notify() isn't checking error of underlying QEMUFile, those resources are kept open. This patch checks it and calls migrate_fd_error() in case of error.

We add qemu_peek_buffer, that is identical to qemu_get_buffer, just that it don't update f->buf_index. We add a paramenter to qemu_peek_byte() to be able to peek more than one byte. Once this is done, to see if we have a subsection we look: - 1st byte is QEMU_VM_SUBSECTION - 2nd byte is a length, and is bigger than section name - 3rd element is a string that starts with section_name So, we shouldn't have false positives (yes, content could still get us wrong but probabilities are really low). v2: - Alex Williamsom found that we could get negative values on index. - Rework code to fix that part. - Rewrite qemu_get_buffer() using qemu_peek_buffer() v3: - return "done" on error case v4: - fix qemu_file_skip() off by one.

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.

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).

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.

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.

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 4dbe19e1. Fix this by splitting up pic_init_reset from pic_reset and clearing the register in the latter. Signed-off-by: NJan Kiszka <jan.kiszka@siemens.com> Signed-off-by: NBlue Swirl <blauwirbel@gmail.com>

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.

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.
