For full change detail consult the git history: + + http://git.linaro.org/gitweb?p=qemu/qemu-linaro.git;a=summary + +Bug numbers refer to Launchpad qemu-linaro bugs, eg: +https://bugs.launchpad.net/qemu-linaro/+bug/703094 + +version 2012.07: + - Fixes #1008338: QEMU built to use the 'Tiny Code + Interpreter' rather than JITting to native code now + works correctly (previously it would hang booting a + Linux guest). + +version 2012.06: + - No significant changes, rebased onto upstream v1.1.0. + +version 2012.05: + - Fixes #978694: Beagle bootrom emulation now correctly handles + FAT12/FAT16 images (thanks to Peter Chubb for the bug report + and patch). + - We now support running ARM BE8 userspace binaries (ie + byte-invariant big-endian data and little-endian code). + +version 2012.04: + - Fixes #928432: compiling spice support for i386 should + no longer give compile warnings/errors. + - Fixes #953544: 'SETEND' in Thumb mode should now UNDEF, + in line with the behaviour for the ARM encoding. + - Fixes #956799: add support for the ppoll syscall for + ARM linux-user emulation. + - Fixes #970252: add the OMAP36xx UART FIFO status registers + (thanks to Jan Vesely for the bug report and patch). + +version 2012.03: + - Fixes #932856: the OMAP3 boot rom emulation now tries + sector 256 in raw mode as well as sector 0. + - Fixes #931940: the PL031 RTC model now correctly raises + interrupts when the alarm timer expires. + - Fixes #928555: compiling on ARM systems with GLib 2.31 + or better now works (we were previously failing due to + deprecation warnings on thread API functions). + - Fixes #885239: booting Linux on models using XScale CPUs + now works (a regression from upstream QEMU which has always + been present in qemu-linaro). + - Fixes #928432: compilation failures due to warnings in + Spice code on 32 bit hosts. + - Fixes #906922: we now default to enabling 'reserve memory + for guest' on 64 bit hosts in linux-user-mode. This + significantly reduces the chances of QEMU being unable to + satisfy a guest process mmap() request. + - Fixes #947888: the emulation of /proc/self/maps has been + improved. In particular the check for "%n in a format string + must be in a read-only area of memory" in the glibc in Ubuntu + Precise will now pass rather than always failing. (This was + causing some invocations of gpg to fail which in turn meant + using live-build to create Linaro images was failing.) + (Thanks to Alexander Graf of SuSE for these fixes.) + - QEMU's built-in boot loader now supports passing a device + tree blob to the kernel: if you boot with -kernel mykernel + (and optionally -initrd myinitrd) you can now also use the + new command line option -dtb my.dtb to pass a device tree. + - This version includes an initial implementation of a model + of the Samsung Exynos4210 SoC, used by board models 'nuri' and + 'smdkc210' (thanks to Evgeny Voevodin, Maksim Kozlov, Igor + Mitsyanko and Dmitry Solodkiy from Samsung, who submitted this + work to upstream QEMU). + - This version includes an initial implementation of a model + of the Calxeda Highbank SoC, used by board model 'highbank' + (thanks to Rob Herring and Mark Langsdorf of Calxeda, who + submitted this work to upstream QEMU). + +version 2012.02: + - Fixes #926102: prctl(PR_SET_NAME, ...) not supported. Fixes + usermode qemu running some perl scripts (as of perl 5.14). + - Fixes #913925: cpsie f instruction not reflected in FAULTMASK + (M profile) + - Simplified Cortex-A15 CPU definition, which can boot Linux. + +version 2012.01: + - Fixes #883133: we no longer assert on startup when running on + ARM systems with brk address space randomization enabled + - Fixes #870990: compiling on ARM systems for Thumb2 with + --enable-debug now works + - Fixes #903239: usermode emulation now includes support for + various previously missing *xattr syscalls + - Fixes #905697: trying to enable the prefetch engine in the + OMAP GPMC model might trigger an assertion failure + - We now have a (dummy) model of the L2x0/PL310 L2 cache + controller (thanks to Rob Herring and Mark Langsdorf) + +version 2011.12: + - There are no Linaro-specific changes of note in this release + +version 2011.11: + - The ARM vexpress-a9, versatilepb, versatileab and realview-* + boards now have audio support (thanks to Mathieu Sonet who + contributed a PL041 implementation upstream) + - Support for multiple instances of the "-sd" option on the + command line has been dropped; this was never present in + upstream QEMU and has been removed for consistency. Use + "-drive,if=sd,index=N,file=file.img" for N=0,1,2... instead + - Fixes #886980: 8 and 16 bit reads from the OMAP GPIO module + would crash due to an infinite recursion + +version 2011.10: + - Beagle models now support USB networking (run the model with + "-usb -device usb-net,netdev=mynet -netdev user,id=mynet") + - Instructions introduced with the Cortex-A15 (ARM mode + SDIV and UDIV, and the VFPv4 fused multiply-accumulate + instructions VFMA, VFMS, VFNMA, VFNMS) are now supported + in linux-user mode + - Fixes a bug which would cause returning of the wrong NaN values + in some cases (when more than one input is a NaN or when the + "default NaN" should be returned) + +version 2011.09: + - linux-user mode now supports the 64 bit cmpxchg kernel helpers + (only needed for applications compiled for ARMv6 or lower) + - correct a bug which would cause a crash trying to use USB + on the n800 and n810 models + - PL111 display controller now supported;
