2011-08-21Check for presence of compiler -pthread flag.Brad1-1/+1
OpenBSD / FreeBSD and some other OS's require the use of cc -pthread to link threaded programs so have QEMU's configure script check for the presence of the flag and use it if so. Signed-off-by: Brad Smith <brad@comstyle.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2011-08-21monitor: Show combined protection bits in "info mem"Austin Clements1-3/+7
Previously, "info mem" considered and displayed only the last-level protection bits for a memory range, which doesn't accurrately represent the protection of that range. Now it shows the combined protection. Signed-off-by: Austin Clements <amdragon@mit.edu> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-08-21monitor: Fix "info mem" to print the last memory rangeAustin Clements1-0/+6
"info mem" groups its output into contiguous ranges with identical protection bits, but previously forgot to print the last range. Signed-off-by: Austin Clements <amdragon@mit.edu> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-08-21monitor: Prevent sign-extension of 32-bit addresses printed by info memAustin Clements1-2/+4
Previously, on 32-bit i386, info mem used signed 32-bit int's to store the page table indexes. As a result, address calculation was done in 32 bits and then incorrectly sign-extended to 64 bits, yielding output like ffffffffef000000-ffffffffef031000 0000000000031000 ur- ffffffffef7bc000-ffffffffef7bd000 0000000000001000 urw ffffffffef7bd000-ffffffffef7be000 0000000000001000 ur- This makes these indexes unsigned, which yields correct output 00000000ef000000-00000000ef031000 0000000000031000 ur- 00000000ef7bc000-00000000ef7bd000 0000000000001000 urw 00000000ef7bd000-00000000ef7be000 0000000000001000 ur- Signed-off-by: Austin Clements <amdragon@mit.edu> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-08-21w32: Fix format string regressionStefan Weil1-1/+1
Commit 953ffe0f935f40c0d6061d69e76e0339393b54f8 introduced FMT_pid which is wrong for w32 and w64 getpid(): those getpid() implementations always return an int value. Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-08-21w64: Add definition of FMT_pidStefan Weil1-0/+2
For mingw-w64, pid_t is _pid_t which is __int64, so this platform needs its own definition of FMT_pid. Reviewed-by: Andreas Färber <andreas.faerber@web.de> Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-08-21Fix conversions from pointer to tcg_target_longStefan Weil2-2/+2
tcg_gen_exit_tb takes a parameter of type tcg_target_long, so the type casts of pointer to long should be replaced by type casts of pointer to tcg_target_long. These changes are needed for build environments where sizeof(long) != sizeof(void *), especially for w64. See 4b4a72e55660abf7efe85aca78762dcfea5519ad which fixed the same issue for the other targets.

2011-08-20target-cris/opcode-cris.h: rename REG_PC/SP to CRIS_REG_PC/SPPeter Maydell1-6/+6
The REG_PC constant used in opcode-cris.h can clash with a similar define in system include files. In particular the Ubuntu Lucid SPARC signal.h will define REG_PC, and since qemu-common.h now includes signal.h this was causing compile failures. Rename the constants to avoid this issue. (NB that REG_SP is not actually used within QEMU.) Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Edgar E. Iglesias <edgar.iglesias@gmail.com>
2011-08-16scsi: do not overwrite memory on REQUEST SENSE commands with a large bufferPaolo Bonzini1-1/+2
Other scsi_target_reqops commands were careful about not using r->cmd.xfer directly, and instead always cap it to a fixed length. This was not done for REQUEST SENSE, and this patch fixes it.

This patch fixes build when any of the include paths from QEMU_CFLAGS contains a header file with similar name to a header file in qemu sources. I hit it with error.h included by qapi/qapi-types-core.h. GCC decided to use /usr/include/alsa/error.h instead of qemu's error.h.

2011-08-12configure: Disable guest_agent for mingw32Stefan Weil1-0/+1
guest_agent is not supported for mingw32, so the default value should be 'no', not 'yes'. This removes the dependencies to glib-2.0 and python which makes native and cross builds for w32 much easier (no need to get and install these extra packages). It also avoids the problems caused by different bitfield alignment which is required by glib-2.0. It is still possible to set guest_agent=yes via configure option.

2011-08-12scsi: add support for unit attention conditionsPaolo Bonzini3-2/+94
Unit attention conditions override any sense data the device already has. Their signaling and clearing is handled entirely by the SCSIBus code, and they are completely transparent to the SCSIDevices.

2011-08-12scsi: introduce SCSICommandPaolo Bonzini2-54/+58

2011-08-12scsi: pass cdb already to scsi_req_newPaolo Bonzini6-15/+18
Right now the CDB is not passed to the SCSIBus until scsi_req_enqueue. Passing it to scsi_req_new will let scsi_req_new dispatch common requests through different reqops. Moving the memcpy to scsi_req_new is a hack that will go away as soon as scsi_req_new will also take care of the parsing.

2011-08-12scsi: move sense handling to generic codePaolo Bonzini5-112/+111
With this patch, sense data is stored in the generic data structures for SCSI devices and requests. The SCSI layer takes care of storing sense data in the SCSIDevice for the subsequent REQUEST SENSE command. At the same time, get_sense is removed and scsi_req_get_sense can use an entirely generic implementation.

2011-08-12scsi: pass status when completingPaolo Bonzini4-31/+25
A small improvement in the SCSI request API. Pass the status at the time the request is completed, so that we can assert that no request is completed twice.

2011-08-12vscsi: always use get_sensePaolo Bonzini1-70/+21
vscsi supports autosensing by providing sense data directly in the response. When get_sense was added, the older state machine approach that sent REQUEST SENSE commands separately was left in place. Remove it, all existing SCSIDevices do support autosensing and the next patches will make the support come for free from the SCSIBus.

2011-08-12scsi-disk: no need to call scsi_req_data on a short readPaolo Bonzini1-3/+0
In fact, if the HBA's transfer_data callback goes on with scsi_req_continue the request will be completed successfully instead of showing a failure. It can even cause a segmentation fault. An easy way to trigger it is "eject -f cd" during installation (during media test if the installer does something like that).

2011-08-12pc: make vgabios exit port more usefulAnthony Liguori1-2/+2
We've always listened on port 501 for vgabios panic messages. In the entire time I've worked on QEMU, I've never actually seen a vgabios panic message :-) If we change the semantics of this port a little bit, it makes it possible to use it for more interesting use-cases. I chose this approach instead of adding a new I/O port because it avoids having a guest visible change. This change allows single-byte access to port 501 and also uses the value written to construct an exit code. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
