2012-08-26tcg/ia64: fix and optimize ld/st slow pathAurelien Jarno1-15/+23
Store slow path has been broken in e141ab52d: - the arguments are shifted before the last one (mem_index) is written. - the shift is done for both slow and fast paths. Fix that. Also optimize a bit by bundling the move together. This still can be optimized, but it's better to wait for a decision to be taken on the arguments order.

2012-08-26tcg/arm: Fix broken CONFIG_TCG_PASS_AREG0 codePeter Maydell1-93/+144
The CONFIG_TCG_PASS_AREG0 code for calling ld/st helpers was broken in that it did not respect the ABI requirement that 64 bit values were passed in even-odd register pairs. The simplest way to fix this is to implement some new utility functions for marshalling function arguments into the correct registers and stack, so that the code which sets up the address and data arguments does not need to care whether there has been a preceding env argument.

2012-08-24i8259: add -no-spurious-interrupt-hack optionMatthew Ogilvie5-5/+44
This patch provides a way to optionally suppress spurious interrupts, as a workaround for systems described below: Some old operating systems do not handle spurious interrupts well, and qemu tends to generate them significantly more often than real hardware. Examples: - Microport UNIX System V/386 v 2.1 (ca 1987) (The main problem I'm fixing: Without this patch, it panics sporadically when accessing the hard disk.) - AT&T UNIX System V/386 Release 4.0 Version 2.1a (ca 1991) See screenshot in "QEMU Official OS Support List": http://www.claunia.com/qemu/objectManager.php?sClass=application&iId=9 (I don't have this system to test.) - A report about OS/2 boot lockup from 2004 by Hampa Hug: http://lists.nongnu.org/archive/html/qemu-devel/2004-09/msg00367.html (My patch was partially inspired by his.) Also: http://lists.nongnu.org/archive/html/qemu-devel/2005-06/msg00243.html (I don't have this system to test.)

2012-08-24vga: add some optional CGA compatibility hacksMatthew Ogilvie4-8/+74
This patch adds some optional compatibility hacks (default disabled) to allow Microport UNIX to function under qemu. I've tried to structure it to be easy to add more hacks for other old CGA programs, if anyone ever needs them. Microport UNIX System V/386 v 2.1 (ca 1987) tries to program the CGA registers directly with neither the assistance of BIOS, nor with proper handling of EGA/VGA-only registers. Note that it didn't work on real VGA hardware, either (although in that case, the most obvious problems seemed to be out-of-range hsync and/or vsync signalling, rather than the issues in this patch). Eventually real MDA and/or CGA support might provide an alternative to this patch, although a hybrid approach like this patch might still be useful in marginal cases.

The feature was added in commit cb5a7aa8c32141bb Sep 2008.

2012-08-24vl: fix -hdachs/-hda argument order parsing issuesMatthew Ogilvie1-21/+18
Without this patch, the -hdachs argument had to occur either BEFORE the corresponding "-hda" option, or AFTER the plain disk image name (if neither -hda nor -drive is used). Otherwise it would effectively be ignored. Option -hdachs still has no effect on -drive, but that seems best.

2012-08-23qom: object_delete should unparent the object firstPaolo Bonzini5-10/+2
object_deinit is only called when the reference count goes to zero, and yet tries to do an object_unparent. Now, object_unparent either does nothing or it will decrease the reference count. Because we know the reference count is zero, the object_unparent call in object_deinit is useless. Instead, we need to disconnect the object from its parent just before we remove the last reference apart from the parent's. This happens in object_delete. Once we do this, all calls to object_unparent peppered through QEMU can go away. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2012-08-23target-mips: Enable access to required RDHWR hardware registersMeador Inge1-2/+3
While running in the usermode emulator all of the required* MIPS32r2 RDHWR hardware registers should be accessible (the Linux kernel enables access to these same registers). Note that these registers are still enabled when the MIPS ISA is not release 2. This is OK since the Linux kernel emulates access to them when they are not available in hardware. * There is also the ULR register which is only recommended for full release 2 compliance. Incidentally, accessing this register in the current implementation works fine without flipping its access bit.

2012-08-23monitor: move json init from OPEN event to initAnthony Liguori1-1/+3
At some point in the past, the OPEN event was changed to be issued from a bottom half. This creates a small window whereas a data callback registered in init may be invoked before the OPEN event has been issued. This is reproducible with: echo "{'execute': 'qmp_capabilities'}" | qemu-system-x86_64 -M none -qmp stdio We can fix this for the monitor by moving the parser initialization to init. The remaining state that is set in OPEN appears harmless. Reported-by: Daniel Berrange <berrange@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2012-08-22pci_host: Turn into SysBus-derived QOM typeAndreas Färber2-0/+17
The preceding commits fixed misuses of FROM_SYSBUS() that led people to add a bogus busdev field. For qdev the field order was less relevant but for QOM the PCIHostState field (including the SysBusDevice actually initialized with a value) must be placed first within the state struct. To facilitate accessing the PCIHostState fields, derive all PCI host bridges from TYPE_PCI_HOST_BRIDGE rather than TYPE_SYS_BUS_DEVICE. We can now access PCIHostState QOM-style, with PCI_HOST_BRIDGE() macro.

2012-08-22virtio-blk: hide VIRTIO_BLK_F_CONFIG_WCE from old machine typesStefan Hajnoczi3-2/+6
QEMU has a policy of keeping a stable guest device ABI. When new guest device features are introduced they must not change hardware info seen by existing guests. This is important because operating systems or applications may "fingerprint" the hardware and refuse to run when the hardware changes. To always get the latest guest device ABI, run with x86 machine type "pc". This patch hides the new VIRTIO_BLK_F_CONFIG_WCE virtio feature bit from existing machine types. Only pc-1.2 and later will expose this feature by default. For more info on the VIRTIO_BLK_F_CONFIG_WCE feature bit, see: commit 13e3dce068773c971ff2f19d986378c55897c4a3 Author: Paolo Bonzini <pbonzini@redhat.com> Date: Thu Aug 9 16:07:19 2012 +0200 virtio-blk: support VIRTIO_BLK_F_CONFIG_WCE Also rename VIRTIO_BLK_F_WCACHE to VIRTIO_BLK_F_WCE for consistency with the spec.
