2017-01-09block: Rename raw-{posix,win32} to file-*.cEric Blake8-10/+10
These files deal with the file protocol, not the raw format (the file protocol is often used with other formats, and the raw format is not forced to use the file protocol).

2017-01-09block: Rename raw_bsd to raw-format.cEric Blake3-3/+3
Given that we have raw-win32.c and raw-posix.c, my initial guess at raw_bsd.c was that it was for dealing with raw files using code specific to the BSD operating system (beyond what raw-posix could do). Not so - this name was chosen back in commit e1c66c6 to distinguish that it was a BSD licensed file, in contrast to the then-existing raw.c with an unclear and potentially unusable license. But since it has been more than three years since the rewrite, it's time to pick a more useful name for this file to avoid this type of confusion to future contributors that don't know the backstory, as none of our other files are named solely by the license they use. In reality, this file deals with the raw format, which is useful with any number of protocols, while raw-{win32,posix} deal with the file protocol (and in turn, that protocol is not limited to use with the raw format). So rename raw_bsd to raw-format.c. We could have also used the shorter name raw.c, except that collides with the earlier use of that filename for a different license, and it's better to be safe than risk license pollution. The next patch will also rename raw-win32.c and raw-posix.c to further distinguish the difference in roles. It doesn't hurt that this gets rid of an underscore in the filename, thereby making tab-completion on 'ra<TAB>' easier (now I don't have to type the shift key, which slows things down :) Suggested-by: Daniel P.

2017-01-09hw/arm/virt: Don't incorrectly claim architectural timer to be edge-triggeredPeter Maydell1-4/+30
The architectural timers in ARM CPUs all have level triggered interrupts (unless you're using KVM on a host kernel before 4.4, which misimplemented them as edge-triggered). We were incorrectly describing them in the device tree as edge triggered. This can cause problems for guest kernels in 4.8 before rc6: * pre-4.8 kernels ignore the values in the DT * 4.8 before rc6 write the DT values to the GIC config registers * newer than rc6 ignore the DT and insist that the timer interrupts are level triggered regardless Fix the DT so we're describing reality. For backwards-compatibility purposes, only do this for the virt-2.9 machine onward. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Andrew Jones <drjones@redhat.com>

One of the purposes of VirtBoardInfo was to hold various bits of state about the board. Now we have MachineState and the subclass VirtMachineState to do this. Fold the VirtBoardInfo into VirtMachineState rather than having some flags in one struct and some in another with no useful way to get between them. In the process we drop the code for looking up the memory map and irq map from the CPU model, because in practice we always use the same maps in all cases. For easier code review, this change removes the VirtBoardInfo type but leaves all the variables which used to be VirtBoardInfo* and are now VirtMachineState* with their now-confusing 'vbi' names.

2017-01-06tcg-mips: Add bswap32u and bswap64Jin Guojie1-3/+99
Without the mips32r2 instructions to perform swapping, bswap is quite large, dominating the size of each reverse-endian qemu_ld/qemu_st operation. Create two subroutines in the prologue block. The subroutines require extra reserved registers (TCG_TMP[2, 3]). Using these within qemu_ld means that we need not place additional restrictions on the qemu_ld outputs.
