setup_ioeventfds() is unnecessary and actually causes a segfault when used ioeventfd=on is used on the command-line. Since ioeventfds are handled within the memory API, it can be removed. Signed-off-by:

Add the missing .class_size definition to the arm_gic_info TypeInfo. This fixes the memory corruption and possible segfault that otherwise results when the class struct is allocated at too small a size and the class init function writes off the end of it. Reported-by:

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. Based on commit 9716ef3b for ARM by Peter Maydell. Signed-off-by:

Winwave audio backend has problem with pausing and restart audio out. Unlike other backends, Winwave pausing API does not flush audio buffer. As a result, the previous audio data are played in front of user expected sound when user restart audio. So changes it to waveOutReset() Signed-off-by:

The number of blocks of the device is used to compute the device size in bdrv_getlength()/iscsi_getlength(). For MMC devices, the ReturnedLogicalBlockAddress in the READCAPACITY10 has a special meaning when it is 0. In this case it does not mean that LBA 0 is the last accessible LBA, and thus the device has 1 readable block, but instead it means that the disc is blank and there are no readable blocks. This change ensures that when the iSCSI LUN is loaded with a blank DVD-R disk or similar that bdrv_getlength() will return the correct size of the device as 0 bytes. Signed-off-by: -

Commit 03847837 (scsi-block: remove properties that are not relevant for passthrough, 2012-07-09) removed one property that should have been left there, "bootindex". It also did not touch scsi-generic, while it should have. Fix both problems. Reported-by:

The microMIPS SWP and SDP instructions do not modify GPRs. So their behavior is well defined when RD equals BASE. The MIPS Architecture Verification Programs (AVPs) check that they work as expected. This is required for AVPs to pass. Signed-off-by:

Now that we default to reserving nearly 4GB of RAM for the guest address space when running a 32 bit linux-user guest on 64 bit hosts, users are much more likely to run into it. Reword the message to be more informative about what failed and provide suggestions for how to fix things. Signed-off-by:

In case when TARGET_ABI_BITS == 32 && HOST_LONG_BITS == 64, the last byte of the target dirent structure (aka d_type byte) was never copied from the host dirent structure, thus breaking everything that relies on valid d_type value, e.g. glob(3). Reviewed-by:

Store slow path has been broken in e141ab52 : - 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. Signed-off-by:

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.)

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. Signed-off-by:

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. Signed-off-by:

We do not register ioeventfds unless the IVSHMEM_IOEVENTFD feature is set. The same feature must be checked before releasing the eventfds. Regression introduced by commit 563027cc (ivshmem: use EventNotifier and memory API, 2012-07-05). Reported-by:

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:
