2011-10-25hda: do not mix output and input stream states, RHBZ #740493Marc-André Lureau
Windows 7 may use the same stream number for input and output. Current code will confuse streams. Changes since v1: - keep running_compat[] for migration version 1 - add running_real[] for migration version 2 Signed-off-by: Marc-Andr?

2011-10-25hda: do not mix output and input streams, RHBZ #740493Marc-André Lureau
Windows 7 may use the same stream number for input and output. That will result in lot of garbage on playback. The hardcoded value of 4 needs to be in sync with GCAP streams description and IN/OUT registers. Signed-off-by: Marc-Andr? Lureau <marcandre.lureau@redhat.com> Signed-off-by: malc <av1474@comtv.ru>

2011-10-23m48t59: fix write accessBlue Swirl
Fix incorrect order of arguments, letting writes to NVRAM succeed. It looks like guests never write to the device, only read from it, since the bug originates back to 819385c58b319d9f80d676cefaed0610118f03ac. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2011-10-21pc: Fix floppy drives with if=noneKevin Wolf
Commit 63ffb564 broke floppy devices specified on the command line like -drive file=...,if=none,id=floppy -global isa-fdc.driveA=floppy because it relies on drive_get() which works only with -fda/-drive if=floppy. This patch resembles what we're already doing for IDE, i.e. remember the floppy device that was created and use that to extract the BlockDriverStates where needed.

2011-10-21fdc: Fix floppy port I/OKevin Wolf
The floppy device was broken by commit 212ec7ba (fdc: Convert to isa_register_portio_list). While the old interface provided the port number relative to the floppy drive's io_base, the new one provides the real port number, so we need to apply a bitmask now to get the register number.

2011-10-21xen_disk: Always set feature-barrier = 1Kevin Wolf
The synchronous .bdrv_flush callback doesn't exist any more and a device really shouldn't poke into the block layer internals anyway. All drivers are supposed to have a correctly working bdrv_flush, so let's just hard-code this. Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2011-10-16i8259: Convert to qdevJan Kiszka
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 Kiszka
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 Kiszka
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 Kiszka
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 Kiszka
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 Kiszka
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 Kiszka
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 Kiszka
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 Kiszka
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>
