2015-09-25docs: describe the QEMU build system structure / designDaniel P. Berrange2-0/+515
Developers who are new to QEMU, or have a background familiarity with GNU autotools, can have trouble getting their head around the home-grown QEMU build system.

2015-09-25linux-user: elfload: Provide default for elf_check_archPeter Crosthwaite1-24/+4
For many arch's this macro is defined as the predicatable behaviour of checking the argument for eqaulity against ELF_ARCH. Provide a default define as such, so only archs with special handling (usually allowing multiple EM values) need to provide a def. Arches that do any of: 1: provide this def exactly the same way as the new default (alpha, x86_64) 2: check against ELF_MACHINE while defining ELF_ARCH == ELF_MACHINE (arm, aarch64) 3: check against EM_FOO directly while defining ELF_ARCH == EM_FOO (unicore32, sparc32, ppc32, mips, openrisc, sh4, cris, m86k) have their elf_check_arch removed as the default will provide the correct behaviour.

2015-09-25Makefile: fix build when VPATH is outside GIT treeDaniel P. Berrange1-2/+1
Steve Ellcey / Leon Alrae reported that QEMU fails to build when the VPATH directory is outside of the GIT tree, and the system emulators & tools build is disabled. eg cd .. mkdir build cd build ../qemu/configure --disable-system --disable-tools make (...) make[1]: *** No rule to make target `../qom/object.o', needed by `qemu-aarch64'. Stop. make: *** [subdir-aarch64-linux-user] Error 2 The problem is due to the fact that some sub directory deps were listed against SOFTMMU_SUBDIR_RULES instead of SUBDIR_RULES, so were only processed for system emulators, not user emalutors.

2015-09-25scsi-generic: let guests recognize readonly=on on passthrough devicesPaolo Bonzini1-0/+14
Passed-through SCSI devices can be opened with the readonly=on option. When this happens, Linux filters away write commands so that the guest cannot overwrite the contents of the device. However, the guest does not know that the device is read-only, and accepts writes. The writes only fail later when the page cache is flushed. This patch modifies scsi-generic to modify the MODE SENSE data and set the read-only bit in the device-specific parameters, so that the guest OS treats the disk as write protected.
