2012-10-08vfio-pci: Don't peak at msi_supportedAlex Williamson
Let the init function fail, just don't warn for -ENOTSUP. Signed-off-by: Alex Williamson <alex.williamson@redhat.com>
2012-10-08vfio-pci: Roll the header into the .c fileAlex Williamson
It's only ~100 lines and nobody else should be using this. Suggested by Michael Tsirkin. Signed-off-by: Alex Williamson <alex.williamson@redhat.com>
2012-10-08vfio-pci: No spurious MSIsAlex Williamson
FreeBSD doesn't like these spurious MSIs, remove them as they're mostly paranoia anyway. Signed-off-by: Alex Williamson <alex.williamson@redhat.com>
2012-10-08vfio-pci: Rework MSIX setup/teardownAlex Williamson
We try to do lazy initialization of MSIX since we don't actually need to setup anything until MSIX vectors start getting used. This leads to problems if MSIX is enabled, but never used (we can end up trying to re-enable INTx while it's still enabled). We also run into problems trying to expand our reset function to tear down interrupts as we can then get vector release notifications after we've released data structures. By making explicit initialization and teardown we can avoid both of these problems and behave more similar to bare metal. Signed-off-by: Alex Williamson <alex.williamson@redhat.com>
2012-10-08vfio-pci: Unmap and retry DMA mappingAlex Williamson
Occasionally we get regions added that overlap with existing mappings. These always seems to be in the VGA ROM range. VFIO returns EBUSY for these mapping attempts. We can try a little harder and assume that the latest mapping is correct by removing any overlapping ranges and retrying the original request. Signed-off-by: Alex Williamson <alex.williamson@redhat.com>
2012-10-08vfio-pci: Re-order map/unmapAlex Williamson
This cleans up the next patch that calls unmap from map. Signed-off-by: Alex Williamson <alex.williamson@redhat.com>
2012-10-08vfio-pci: Update slow path INTx algorithmAlex Williamson
We can't afford the overhead of switching out and back into mmap mode around each interrupt, but we can do it lazily via a timer. On INTx interrupt, disable the mmap'd memory regions and set a timer. On every interrupt, push the timer out. If the timer expires and the interrupt is no longer pending, switch back to mmap mode. This has the benefit that things like graphics cards, which rarely or never, fire an interrupt don't need manual user intervention to add the x-intx=off parameter. They'll just remain in mmap mode until they trigger an interrupt, and if they don't continue to regularly fire interrupts, they'll switch back. The default timeout is tuned for network cards so that a ping is just enough to keep them in non-mmap mode, where they have much better latency. It is tunable with an experimental option, x-intx-mmap-timeout-ms. A value of 0 keeps the device in non-mmap mode after the first interrupt. It's possible we could look at the class code of devices and come up with reasonable per-class defaults based on expected interrupt frequency and latency. None of this is used for MSI interrupts and also won't be used if we can bypass through KVM. Signed-off-by: Alex Williamson <alex.williamson@redhat.com>

2012-10-07qemu-barrier: Fix compilation on i386 hostsAurelien Jarno
Commit 1d31fca470648ec66afd8743491bfb5846306341 tried to fix bug introduced by 610b823ef66b993660f1ab1447a769f190e4f3b3 by including qemu-common.h, which breaks the build further. Include compiler.h instead, as suggested by Blue Swirl. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2012-10-07target-sparc: Optimize conditionals using SUBCCRichard Henderson
Aka "normal" comparisons. We now have the infrastructure to pass back non-boolean results from gen_compare. This will automatically get used by both branches and conditional moves. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-10-07target-sparc: Fall through from not-taken trapRichard Henderson
Now that we've cleaned up global temporary allocation, we can continue translating the fallthru path of a conditional trap. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-10-07target-sparc: Cleanup "global" temporary allocationRichard Henderson
There are 6 temporaries that disas_sparc_insn relies on having been allocated. Now that they are no longer referenced across branches, they need not be allocated as local temps. Move the allocation/free of these temporaries to make it clear that they are local to the translation of a single insn.

2012-10-07target-sparc: Move taddcctv and tsubcctv out of lineRichard Henderson
The branches around the exception are maintaining an otherwise unnecessary use of local temps for the cpu destination. Note that gen_op_t{add,sub}_cc were identical to gen_op_{add,sub}_cc. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-10-07target-sparc: Tidy TccRichard Henderson
Share more code between unconditional and conditional paths. Move the computation of the trap number into the conditional BB; avoid using temporaries that have gone out of scope (cpu_tmp32) or rely on local temps (cpu_dst). Fully fold the exception number when the trap number is %g0+imm. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

Commit 610b823ef66b993660f1ab1447a769f190e4f3b3 uses QEMU_GNUC_PREREQ on i386 hosts.
