2015-09-25hmp: added io apic dump statePavel Butsykin
Added the hmp command to query io apic state, may be usefull after guest crashes to understand IRQ routing in guest. Implementation is only for kvm here.

2015-09-18Fix bad error handling after memory_region_init_ram()Markus Armbruster
Symptom: $ qemu-system-x86_64 -m 10000000 Unexpected error in ram_block_add() at /work/armbru/qemu/exec.c:1456: upstream-qemu: cannot set up guest memory 'pc.ram': Cannot allocate memory Aborted (core dumped) Root cause: commit ef701d7 screwed up handling of out-of-memory conditions. Before the commit, we report the error and exit(1), in one place, ram_block_add(). The commit lifts the error handling up the call chain some, to three places. Fine. Except it uses &error_abort in these places, changing the behavior from exit(1) to abort(), and thus undoing the work of commit 3922825 "exec: Don't abort when we can't allocate guest memory". The three places are: * memory_region_init_ram() Commit 4994653 (right after commit ef701d7) lifted the error handling further, through memory_region_init_ram(), multiplying the incorrect use of &error_abort. Later on, imitation of existing (bad) code may have created more. * memory_region_init_ram_ptr() The &error_abort is still there. * memory_region_init_rom_device() Doesn't need fixing, because commit 33e0eb5 (soon after commit ef701d7) lifted the error handling further, and in the process changed it from &error_abort to passing it up the call chain. Correct, because the callers are realize() methods. Fix the error handling after memory_region_init_ram() with a Coccinelle semantic patch: @r@ expression mr, owner, name, size, err; position p; @@ memory_region_init_ram(mr, owner, name, size, ( - &error_abort + &error_fatal | err@p ) ); @script:python@ p << r.p; @@ print "%s:%s:%s" % (p[0].file, p[0].line, p[0].column) When the last argument is &error_abort, it gets replaced by &error_fatal. This is the fix. If the last argument is anything else, its position is reported. This lets us check the fix is complete. Four positions get reported: * ram_backend_memory_alloc() Error is passed up the call chain, ultimately through user_creatable_complete(). As far as I can tell, it's callers all handle the error sanely. * fsl_imx25_realize(), fsl_imx31_realize(), dp8393x_realize() DeviceClass.realize() methods, errors handled sanely further up the call chain. We're good. Test case again behaves: $ qemu-system-x86_64 -m 10000000 qemu-system-x86_64: cannot set up guest memory 'pc.ram': Cannot allocate memory [Exit 1 ] The next commits will repair the rest of commit ef701d7's damage.

2015-09-10igd gfx passthrough: create a isa bridgeTiejun Chen
Currently IGD drivers always need to access PCH by 1f.0. But we don't want to poke that directly to get ID, and although in real world different GPU should have different PCH. But actually the different PCH DIDs likely map to different PCH SKUs. We do the same thing for the GPU. For PCH, the different SKUs are going to be all the same silicon design and implementation, just different features turn on and off with fuses. The SW interfaces should be consistent across all SKUs in a given family (eg LPT). But just same features may not be supported. Most of these different PCH features probably don't matter to the Gfx driver, but obviously any difference in display port connections will so it should be fine with any PCH in case of passthrough. So currently use one PCH version, 0x8c4e, to cover all HSW(Haswell) scenarios, 0x9cc3 for BDW(Broadwell).

2015-07-08hw/i386/pc: reflect any FDC @ ioport 0x3f0 in the CMOSLaszlo Ersek
With the pc-q35-2.4 machine type, if the user creates an ISA FDC manually: -device isa-fdc,driveA=drive-fdc0-0-0 \ -drive file=...,if=none,id=drive-fdc0-0-0,format=raw then the board-default FDC will be skipped, and only the explicitly requested FDC will exist. qtree-wise, this is correct; however such an FDC is currently not registered in the CMOS, because that code is only reached for the board-default FDC. The pc_cmos_init_late() one-shot reset handler -- one-shot because the CMOS is not reprogrammed during warm reset -- should search for any ISA FDC devices, created implicitly (by board code) or explicitly, and set the CMOS accordingly to the ISA FDC(s) with iobase=0x3f0: - if there is no such FDC, report both drives absent, - if there is exactly one such FDC, report its drives in the CMOS, - if there are more than one such FDCs, then pick one (it is not specified which one), and print a warning about the ambiguity.

2015-07-08hw/i386/pc: factor out pc_cmos_init_floppy()Laszlo Ersek
Extract the pc_cmos_init_floppy() function from pc_cmos_init(). The function sets two RTC registers: floppy drive types (0x10), overwriting the earlier value in there), and REG_EQUIPMENT_BYTE (0x14), setting bits in the prior value.

2015-07-07migration: Add configuration sectionJuan Quintela
It needs to be the first one and it is not optional, that is the reason why it is opencoded. For new machine types, it is required that machine type name is the same in both sides. It is just done right now for pc's. Signed-off-by: Juan Quintela <quintela@redhat.com> Reviewed-by: Dr. David Alan Gilbert <dgilbert@redhat.com>
2015-07-07global_state: Make section optionalJuan Quintela
This section would be sent: a- for all new machine types b- for old machine types if section state is different form {running,paused} that were the only giving us troubles. So, in new qemus: it is alwasy there. In old qemus: they are only there if it an error has happened, basically stoping on target.

2015-07-07ich9: add TCO interface emulationPaulo Alcantara
This interface provides some registers within a 32-byte range and can be acessed through PCI-to-LPC bridge interface (PMBASE + 0x60). It's commonly used as a watchdog timer to detect system lockups through SMIs that are generated -- if TCO_EN bit is set -- on every timeout. If NO_REBOOT bit is not set in GCS (General Control and Status register), the system will be resetted upon second timeout if TCO_RLD register wasn't previously written to prevent timeout. This patch adds support to TCO watchdog logic and few other features like mapping NMIs to SMIs (NMI2SMI_EN bit), system intruder detection, etc. are not implemented yet.
