2018-03-12qapi: Add device ID and head parameters to screendumpThomas Huth
QEMU's screendump command can only take dumps from the primary display. When using multiple VGA cards, there is no way to get a dump from a secondary card or other display heads yet. So let's add a 'device' and a 'head' parameter to the HMP and QMP commands to be able to specify alternative devices and heads with the screendump command, too. Reviewed-by: Daniel P.

2018-03-12spice: add cursor_dmabuf supportGerd Hoffmann
Add support for cursor dmabufs. qemu has to render the cursor for that, so in case a cursor is present qemu allocates a new dmabuf, blits the scanout, blends in the pointer and passes on the new dmabuf to spice-server. Without cursor qemu continues to simply pass on the scanout dmabuf as-is.

2018-03-12vnc: deal with surface NULL pointersGerd Hoffmann
Secondary displays in multihead setups are allowed to have a NULL DisplaySurface. Typically user interfaces handle this by hiding the window which shows the display in question. This isn't an option for vnc though because it simply hasn't a concept of windows or outputs. So handle the situation by showing a placeholder DisplaySurface instead. Also check in console_select whenever a surface is preset in the first place before requesting an update. This fixes a segfault which can be triggered by switching to an unused display (via vtrl-alt-<nr>) in a multihead setup, for example using -device virtio-vga,max_outputs=2.

2018-03-12build: try improve handling of clang warningsGerd Hoffmann
This patch disables the pragma diagnostic -Wunused-but-set-variable for clang in util/coroutine-ucontext.c. This in turn allows us to remove it from the configure check, so the CONFIG_PRAGMA_DIAGNOSTIC_AVAILABLE will succeed for clang. With that in place clang builds (linux) will use -Werror by default, which breaks the build due to warning about unaligned struct members. Just turning off this warning isn't a good idea as it indicates portability problems. So make it a warning again, using -Wno-error=address-of-packed-member. That way it doesn't break the build but still shows up in the logs. Now clang builds qemu without errors. Well, almost. There are some left in the rdma code. Leaving that to the rdma people. All others can use --disable-rdma to workarounds this.

2018-03-09linux-user: init_guest_space: Clarify page alignment logicLuke Shumaker
There are 3 parts to this change: - Add a comment showing the relative sizes and positions of the blocks of memory - introduce and use new aligned_{start,size} instead of adjusting real_{start_size} - When we clean up (on failure), munmap(real_start, real_size) instead of munmap(aligned_start, aligned_size). It *shouldn't* make any difference, but I will admit that this does mean we are making the syscall with different values, so this isn't quite a no-op patch.

2018-03-09linux-user: init_guest_space: Correctly handle guest_start in commpage ↵Luke Shumaker
initialization init_guest_commpage needs to check if the mapped space, which ends at real_start+real_size overlaps with where it needs to put the commpage, which is (assuming sane qemu_host_page_size) guest_base + 0xffff000, where guest_base is real_start - guest_start. [guest_base][ 0xffff0000 ][commpage] [guest_base][guest_start][real_size] [commpage] [ real_start ][real_size] [commpage] ^ fail if this gap < 0 Since init_guest_commpage wants to do everything relative to guest_base (rather than real_start), it obviously needs to be comparing 0xffff0000 against guest_start+real_size, not just real_size. This bug has been present since 806d102141b99d4f1e55a97d68b7ea8c8ba3129f in 2012, but guest_start is usually 0, and prior to v2.11 real_size was usually much smaller than 0xffff0000, so it was uncommon for it to have made a difference.

Change definition of GUEST_ADDR_MAX to always be the last valid guest address. Account for this change in open_self_maps. Add macro guest_addr_valid that verifies if the guest address is valid. Add function guest_range_valid that verifies if address range is within guest address space and does not wrap around. Use that macro in mmap/munmap/mprotect/mremap/shmat for error checking.

2018-03-09sdcard: Add the Tuning Command (CMD19)Philippe Mathieu-Daudé
From the "Physical Layer Simplified Specification Version 3.01": A known data block ("Tuning block") can be used to tune sampling point for tuning required hosts. [...] This procedure gives the system optimal timing for each specific host and card combination and compensates for static delays in the timing budget including process, voltage and different PCB loads and skews. [...] Data block, carried by DAT[3:0], contains a pattern for tuning sampling position to receive data on the CMD and DAT[3:0] line.

2018-03-09hw/arm/virt: Support -machine gic-version=maxPeter Maydell
Add support for passing 'max' to -machine gic-version. By analogy with the -cpu max option, this picks the "best available" GIC version whether you're using KVM or TCG, so it behaves like 'host' when using KVM, and gives you GICv3 when using TCG. Also like '-cpu host', using -machine gic-version=max' means there is no guarantee of migration compatibility between QEMU versions; in future 'max' might mean '4'.

2018-03-09target/arm: Make 'any' CPU just an alias for 'max'Peter Maydell
Now we have a working '-cpu max', the linux-user-only 'any' CPU is pretty much the same thing, so implement it that way. For the moment we don't add any of the extra feature bits to the system-emulation "max", because we don't set the ID register bits we would need to to advertise those features as present.

2018-03-09target/arm: Add "-cpu max" supportPeter Maydell
Add support for "-cpu max" for ARM guests. This CPU type behaves like "-cpu host" when KVM is enabled, and like a system CPU with the maximum possible feature set otherwise. (Note that this means it won't be migratable across versions, as we will likely add features to it in future.)

2018-03-09target/arm: Move definition of 'host' cpu type into cpu.cPeter Maydell
Move the definition of the 'host' cpu type into cpu.c, where all the other CPU types are defined. We can do this now we've decoupled it from the KVM-specific host feature probing. This means we now create the type unconditionally (assuming we were built with KVM support at all), but if you try to use it without -enable-kvm this will end up in the "host cpu probe failed and KVM not enabled" path in arm_cpu_realizefn(), for an appropriate error message.
