2010-01-11lsi: have lsi_request for the whole life time of the request.Gerd Hoffmann
Right now lsi_request is allocated when a request is queued and released when a request is unqueued. With this patch applied the lsi_request is kept for the whole lifetime of the scsi request. Rationale: We can use it for per-request data then. The patch does that already for the request tag.

2010-01-11MCE: Fix bug of IA32_MCG_STATUS after system resetHuang Ying
Now, if we inject a fatal MCE into guest OS, for example Linux, Linux will go panic and then reboot. But if we inject another MCE now, system will reset directly instead of go panic firstly, because MCG_STATUS.MCIP is set to 1 and not cleared after reboot. This is does not follow the behavior in real hardware. This patch fixes this via set env->mcg_status to 0 during system reset.

2010-01-08linuxboot: fix gdt address calculationAvi Kivity
The gdt address calculation in linuxboot.bin is broken in two ways: first it loads %cs into %eax, but that instruction leaves the high bits of %eax undefined and we did not clear them. Secondly, we completely ignore the incorrect %eax, and use the undefined %ebx instead. With these issues fixed, linuxboot works again.

2010-01-08block/vdi: allow disk sizes not multiple of block sizeFrançois Revol
The disk image I created from my old laptop disk with VBoxManage internalcommand converthd obviously was not a multiple of 1MB as when created from scratch. This fixes QEMU refusing it. We still require the size to be a multiple of sector size though. It then boots correctly. Allow opening VDI images with size not multiple of 1MB (as when converted from a raw disk).

2010-01-08debugcon: support for debugging consoles (e.g. Bochs port 0xe9)H. Peter Anvin
Add generic support for debugging consoles (simple I/O ports which when written to cause debugging output to be written to a target.) The current implementation matches Bochs' port 0xe9, allowing the same debugging code to be used for both Bochs and Qemu. There is no vm state associated with the debugging port, simply because it has none -- the entire interface is a single, stateless, write-only port. Most of the code was cribbed from the serial port driver. v2: removed non-ISA variants (they can be introduced when/if someone wants them, using code from the serial port); added configurable readback (Bochs returns 0xe9 on a read from this register, mimic that by default) This retains the apparently somewhat controversial user friendly option, however. v3: reimplemented the user friendly option as a synthetic option ("-debugcon foo" basically ends up being a parser-level shorthand for "-chardev stdio,id=debugcon -device isa-debugcon,chardev=debugcon") -- this dramatically reduced the complexity while keeping the same level of user friendliness. v4: spaces, not tabs. v5: update to match current top of tree. Calling qemu_chr_open() already during parsing no longer works; defer until we are parsing the other console-like devices. Signed-off-by: H.

2010-01-08Use vpath directivePaolo Bonzini
The vpath directive has two advantages over the VPATH variable: 1) it allows to skip searching of .o files; 2) the default semantics are to append to the vpath, so there is no confusion between "VPATH=xyz" and "VPATH+=xyz". Since "vpath %.c %.h PATH" is not valid, I'm introducing a wrapper macro to append one or more directories to the vpath.

2010-01-07Drop --whole-archive and static librariesAndreas Färber
Juan has contributed a cool Makefile infrastructure that enables us to drop static libraries completely: Move shared obj-y definitions to Makefile.objs, prefixed {common-,hw-,user-}, and link those object files directly into the executables. Replace HWLIB by HWDIR, specifying only the directory. Drop --whole-archive and ARLIBS in Makefiles and configure. Drop GENERATED_HEADERS dependency in rules.mak, since this rebuilds all common objects after generating a target-specific header; add dependency rules to Makefile and Makefile.target instead. v2: - Don't try to include /config.mak for user emulators - Changes to user object paths ("Quickfix for libuser.a drop") were obsoleted by "user_only: compile everything with -fpie" (Kirill A. Shutemov) v3: - Fix dependency modelling for tools - Remove comment on GENERATED_HEADERS obsoleted by this patch Signed-off-by: Andreas Färber <afaerber@opensolaris.org> Cc: Blue Swirl <blauwirbel@gmail.com> Cc: Palle Lyckegaard <palle@lyckegaard.dk> Cc: Ben Taylor <bentaylor.solx86@gmail.com> Cc: Juan Quintela <quintela@trasno.org> Cc: Kirill A.

2010-01-07vnc: Fix artifacts in hextile decodingAnthony Liguori
02c2b87 introduced a regression whereas the foreground color in a hextile update was not being properly invalidated leading to artifacts.
