2010-02-10qcow2: Fix signedness bugsKevin Wolf
Checking for return codes < 0 isn't really going to work with unsigned types. Use signed types instead. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-02-10qemu-img: Fix qemu-img can't create qcow image based on read-only imageSheng Yang
Commit 03cbdac7 "Disable fall-back to read-only when cannot open drive's file for read-write" result in read-only image can't be used as backed image in qemu-img.

2010-02-10doc: Update mingw cross compile instructionsScott Tsai
The "Cross compilation for Windows with Linux" section of qemu-doc.texi still instructs the user to use 'configure --enable-mingw32' even after the option was removed in Aug 2008: http://git.savannah.gnu.org/cgit/qemu.git/commit/?id=cd01b4a312248dd4e12c3d389d1a349cea4015d8 This documentation only change updates the instructions to: * Remove use of '--enable-mingw32' in the configure example * Correct the 'sdl-config' script name * Remove references to i386-mingw32msvc.tar.gz which no longer exists in recent SDL releases * Document the zlib dependency Signed-off-by: Scott Tsai <scottt.tw@gmail.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-02-10Do not ignore error, if open file failed (-serial /dev/tty)Evgeniy Dushistov
In case, when qemu is executed with option like -serial /dev/ttyS0, report if there are problems with opening of devices. At now errors are silently ignoring. Signed-off-by: Evgeniy Dushistov <dushistov@mail.ru> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-02-10Documentation: Add build support for documentation in pdf formatStefan Weil
Makefile already supported dvi, html and info formats, but pdf was missing. pdf is especially convenient for printing and for documentation reviews. I hope it will help to improve qemu's documentation. Make now supports the new target 'pdf' which will create qemu-doc.pdf and qemu-tech.pdf. It is also possible to build both files individually. texi2pdf and texi2dvi are rather noisy, so normally some less important warnings are suppressed. When make is called with V=1 (verbose mode), warnings are not suppressed. The patch also sorts the documentation targets alphabetically and wraps a line which was too long.

The #ifdef CONFIG_SOLARIS below was useless without this patch. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

Same as what qemu-kvm does. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-02-10do not loop on an incomplete io_thread_fd readPaolo Bonzini
No need to loop if less than a full buffer is read, the next read would return EAGAIN. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-02-09Try not to exceed max downtime on stage3Liran Schour
Move to stage3 only when remaining work can be done below max downtime. Use qemu_get_clock_ns for measuring read performance. Signed-off-by: Liran Schour <lirans@il.ibm.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-02-09Count dirty blocks and expose an API to get dirty countLiran Schour
This will manage dirty counter for each device and will allow to get the dirty counter from above. Signed-off-by: Liran Schour <lirans@il.ibm.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-02-09Tranfer dirty blocks during iterative phaseLiran Schour
Start transfer dirty blocks during the iterative stage. That will reduce the time that the guest will be suspended Signed-off-by: Liran Schour <lirans@il.ibm.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-02-09add qemu_get_clock_nsPaolo Bonzini
Some places use get_clock directly because they want to access the rt_clock with nanosecond precision. Add a function to do exactly that instead of using internal interfaces. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-02-09Remove unused codeLiran Schour
blk_mig_save_bulked_block is never called with sync flag. Remove the sync flag. Calculate bulk completion during blk_mig_save_bulked_block. Remove unused constants. Signed-off-by: Liran Schour <lirans@il.ibm.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-02-09kvm: move kvm to use memory notifiersMichael S. Tsirkin

2010-02-09kvm: move kvm_set_phys_mem aroundMichael S. Tsirkin
move kvm_set_phys_mem so that it will be later available earlier in the file. needed for next patch using memory notifiers. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Acked-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-02-09qemu: memory notifiersMichael S. Tsirkin
This adds notifiers for phys memory changes: a set of callbacks that vhost can register and update kernel accordingly. Down the road, kvm code can be switched to use these as well, instead of calling kvm code directly from exec.c as is done now. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-02-09tcg/mips: fix crash in tcg_out_qemu_ld()Aurelien Jarno
The address register is overriden when it corresponds to v0 and the fast path is taken, which leads to a crash. Fix that by using the a0 register instead. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-02-09target-sh4: MMU: separate execute and read/write permissionsAurelien Jarno
On SH4, the ITLB and UTLB configurations are memory mapped, so loading ITLB entries from UTLB has to be simulated correctly. For that the QEMU TLB has to be handle the execute (ITLB) and read/write permissions (UTLB) seperately. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-02-09target-sh4: MMU: fix store queue addressesAurelien Jarno
The store queues are located from 0xe0000000 to 0xe3ffffff. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2010-02-09target-sh4: MMU: reduce the size of a TLB entryAurelien Jarno
Reduce the size of the TLB entry from 32 to 16 bytes, reorganising members and using a bit field. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-02-09target-sh4: MMU: optimize UTLB accessesAurelien Jarno
With the current code, the QEMU TLB is setup to match the read/write mode of the MMU fault. This means when read access is done, the page is setup in read-only mode. When the page is later accessed in write mode, an MMU fault happened, and the page is switch in write-only mode. This flip-flop causes a lot of calls to the MMU code and slow down the emulation. This patch changes the MMU emulation, so that the QEMU TLB is setup to match the UTLB protection key. This impressively increase the speed of the emulation.

2010-02-09target-sh4: MMU: fix ITLB priviledge checkAurelien Jarno
There is an ITLB access violation if SR_MD=0 (user mode) while the high bit of the protection key is 0 (priviledge mode). Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-02-09target-sh4: MMU: simplify call to tlb_set_page()Aurelien Jarno
tlb_set_page() doesn't need addresses with offset, but simply the page aligned addresses. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-02-09target-sh4: MMU: fix mem_idx computationAurelien Jarno
The mem_idx is wrongly computed. As written in target-sh4/cpu.h, mode 0 corresponds to kernel mode (SR_MD = 1), while mode 1 corresponds to user mode (SR_MD = 0). Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-02-09sh7750: handle MMUCR TI bitAurelien Jarno
When the MMUCR TI bit is set, all the UTLB and ITLB entries should be flushed. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
