2010-02-10Documentation: Use UTF-8 encoding and fix one wrong encodingStefan Weil
At least for Linux distributions UTF-8 is now standard, so the QEMU documentation should use this encoding, too. Even if there was currently only a single special character using ISO-8859-1, this might change in the future. So the texinfo keywords @documentlanguage and @documentencoding now document the language and the encoding. The special character was changed to UTF-8 (it could also have been changed to an x, but the original cross looks really nice if it is displayed correctly). These changes fix the html presentation at http://www.qemu.org/qemu-doc.html#SEC65 (ARM System emulator).

2010-02-10Documentation: Add direntry for info formatStefan Weil
update-info-dir maintains an index of all available documentation in info format (the file /usr/share/info/dir). It reads special @direntry tags in info files. This patch (extracted from a larger patch provided by Dirk Ullrich) adds these tags for qemu-doc.info and qemu-tech.info.

2010-02-10block: saner flags filtering in bdrv_open2Christoph Hellwig
Clean up the current mess about figuring out which flags to pass to the driver. BDRV_O_FILE, BDRV_O_SNAPSHOT and BDRV_O_NO_BACKING are flags only used by the block layer internally so filter them out directly. Previously BDRV_O_NO_BACKING could accidentally be passed to the drivers, but wasn't ever used. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2010-02-10block: BLOCK_IO_ERROR QMP eventLuiz Capitulino
This commit introduces the bdrv_mon_event() function, which should be called by block subsystems (eg. IDE) when a I/O error occurs, so that an QMP event is emitted. The following information is currently provided in the event: - device name - operation (ie. "read" or "write") - action taken (eg. "stop") Event example: { "event": "BLOCK_IO_ERROR", "data": { "device": "ide0-hd1", "operation": "write", "action": "stop" }, "timestamp": { "seconds": 1265044230, "microseconds": 450486 } } Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

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.

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: 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

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>
