2012-04-06Userspace ARM BE8 supportPaul Brook
Add support for ARM BE8 userspace binaries. i.e. big-endian data and little-endian code. In principle LE8 mode is also possible, but AFAIK has never actually been implemented/used. System emulation doesn't have any useable big-endian board models, but should in principle work once you fix that. Dynamic endianness switching requires messing with data accesses, preferably with TCG cooperation, and is orthogonal to BE8 support. Signed-off-by: Paul Brook <paul@codesourcery.com> [PMM: various changes, mostly as per my suggestions in code review: * rebase * use EF_ defines rather than hardcoded constants * make bswap_code a bool for future VMSTATE macro compatibility * update comment in cpu.h about TB flags bit field usage * factor out load-code-and-swap into arm_ld*_code functions and get_user_code* macros * fix stray trailing space at end of line * added braces in disas.c to satisfy checkpatch ] Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Riku Voipio <riku.voipio@linaro.org>

Update the EF_ARM_* constants (for the ELF header e_flags field) to include the newer flags specified for later versions of the ABI. (This set of constants is from include/elf/arm.h from binutils-2.17 and so licensed under GPL-v2-or-later.)

2012-04-06linux-user/arm/syscall_nr.h: Add syscall number for ppollPeter Maydell
The list of ARM syscall numbers was missing the entry for ppoll, which meant we were accidentally not providing it. (This wasn't causing any practical issues beyond warnings about unimplemented syscalls, because glibc will fall back to another code path if the syscall isn't present.)

2012-04-06linux-user: reserve 4GB of vmem for 32-on-64Alexander Graf
When running 32-on-64 bit guests, we should always reserve as much virtual memory as we possibly can for the guest process, so it can never overlap with QEMU address space. Fortunately we already have the infrastructure for that. All that's missing is some sane default value to also make use of it!

2012-04-06linux-user: resolve reserved_va vma downwardsPeter Maydell
After consulting with Paul Brook, we concluded that it's best to search the VMA space downwards, so that we don't even get the chance to conflict with the brk range.

2012-04-06linux-user: take RESERVED_VA into account for g2h_valid()Alexander Graf
When running with -R (RESERVED_VA > 0) all guest virtual addresses are within the [0..RESERVED_VA] range. Reflect this with g2h_valid() too so we can safely check for boundaries of our guest address space. This is required to have the /proc/self/maps code not show maps that aren't accessible from the guest process's point of view.

2012-04-06linux-user: fix BLK ioctl argumentsAlexander Graf

2012-04-06linux-user: improve fake /proc/self/stat making `ps` not segfault.Fabio Erculiani
With the current fake /proc/self/stat implementation `ps` is segfaulting because it expects to read PID and argv[0] as first and second field respectively, with the latter being enclosed between backets.

2012-04-02qdev: give all devices a canonical pathPaolo Bonzini
A strong limitation of QOM right now is that unconverted ports (e.g. all...) do not give a canonical path to devices that are part of the board. This in turn makes it impossible to replace PROP_PTR with a QOM link for example.

2012-04-02qdev: add children before qdev_initPaolo Bonzini
We want the composition tree to to be in order by the time we call qdev_init, so that a single set of the toplevel realize property can propagate all the way down the composition tree. This is not the case so far. Unfortunately, this is incompatible with calling qdev_init in the constructor wrappers for devices, so for now we need to unattach some devices that are created through those wrappers. This will be fixed by removing qdev_init and instead setting the toplevel realize property after machine init.

2012-04-02serial: clear LSR.TEMT when populating the TSRAnthony Liguori
We never actually clear the TEMT (transmit sending register empty) flag when populating the TSR. We set the flag, but since it's never cleared, setting it is sort of pointless.. I found this with a unit test case. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-04-02serial: fix retry logicAnthony Liguori
I'm not sure if the retry logic has ever worked when not using FIFO mode. I found this while writing a test case although code inspection confirms it is definitely broken. The TSR retry logic will never actually happen because it is guarded by an 'if (s->tsr_rety > 0)' but this is the only place that can ever make the variable greater than zero. That effectively makes the retry logic an 'if (0)'. I believe this is a typo and the intention was >= 0. Once this is fixed though, I see double transmits with my test case. This is because in the non FIFO case, serial_xmit may get invoked while LSR.THRE is still high because the character was processed but the retransmit timer was still active. We can handle this by simply checking for LSR.THRE and returning early. It's possible that the FIFO paths also need some attention.

2012-03-31Fix conversion from lower to upper case with Turkish localeStefan Weil
Some locale settings let make fail or create wrong results because tr '[:lower:]' '[:upper:]' which is used to convert from lower to upper case depends on the locale. With locale tr_TR.UTF-8, lower case 'i' is not converted to 'I'. This results in wrong entries in config-host.h like these ones: #define CONFIG_QEMU_PREFiX "/usr/local" #define CONFIG_QEMU_BiNDiR "/usr/local/bin" This problem was reported by Emre Ersin. The same problem occurs when configure creates the target specific files config-target.mak. They get wrong declarations: TARGET_CRiS=y TARGET_i386=y TARGET_MiCROBLAZE=y TARGET_MiPS64=y TARGET_MiPS=y TARGET_UNiCORE32=y It is sufficient to restrict the conversion to the characters a-z. Using this explicit range avoids the dependency on the locale settings and is also shorter. v2: POSIX says that 'tr a-z' is unspecified outside of the POSIX locale, so we must set LC_ALL=C to make sure that we are using POSIX (hint from Eric Blake, thanks).

2012-03-30slirp: Signal free input buffer space to io-threadJan Kiszka
This massively accelerates slirp reception speed: If data arrives faster than the guest can read it from the input buffer, the file descriptor for the corresponding socket was taken out of the fdset for select. However, the event of the guest reading enough data from the buffer was not signaled. Thus, the io-thread only noticed this change on the next time-driven poll.
