      ide/core: Remove explicit setting of BM_STATUS_INT · 69c38b8f
      由 Kevin Wolf 提交于 
      BM_STATUS_INT is automatically set during ide_set_irq(), there's no reason to
set it manually in addition.

There is even one case where the interrupt status bit was set, but no IRQ was
raised. This is when the PRD table was reached but there is more data to
transfer. The correct behaviour for this case is not to set BM_STATUS_INT.

      ahci: Fix non-NCQ accesses for LBA > 16bits · 1fddfba1
      由 Alexander Graf 提交于 
      AHCI provides two ways of reading/writing data:

 1) NCQ
 2) ATA commands with the LBA in the command FIS

In the second code path, we didn't handle any LBAs that were bigger than
16 bits, so whenever a guest that used high LBA numbers wanted to access
data, the LBA got truncated down to 16 bits, giving the guest garbage.

This patch adds support for LBAs higher than 16 bits. I've tested that it
works just fine with SeaBIOS and Linux guests. This patch also unbreaks
the often reported grub errors people have seen with AHCI.

      blockdev: Store -drive option media in DriveInfo · 95b5edcd
      由 Markus Armbruster 提交于 
      DriveInfo is closely tied to -drive, and like -drive, it mixes
information about host and guest part of the block device.  Unlike
DriveInfo, BlockDriverState should be about the host part only.

One of the remaining guest bits there is the "type hint".  -drive
option media sets it, and qdevs "ide-drive", "scsi-disk" and non-qdev
IF_XEN devices check it to pick HD vs. CD.

Communicate -drive option media via new DriveInfo member media_cd
instead.

      ide: Split qdev "ide-drive" into "ide-hd" and "ide-cd" · 1f56e32a
      由 Markus Armbruster 提交于 
      An "ide-drive" is either a hard disk or a CD-ROM, depending on the
associated BlockDriverState's type hint.  Unclean; disk vs. CD belongs
to the guest part, not the host part.

Have separate qdevs "ide-hd" and "ide-cd" to model disk vs. CD in
the guest part.

Keep ide-drive for backward compatibility.

"ide-disk" would perhaps be a nicer name than "ide-hd", but there's
already "scsi-disk", which is like "ide-drive", and will be likewise
split in the next commit.  {ide,scsi}-{hd,cd} is the best consistent
set of names I could find within the backward compatibility
straightjacket.

      change all other clock references to use nanosecond resolution accessors · 74475455
      由 Paolo Bonzini 提交于 
      This was done with:

    sed -i 's/qemu_get_clock\>/qemu_get_clock_ns/' \
        $(git grep -l 'qemu_get_clock\>' )
    sed -i 's/qemu_new_timer\>/qemu_new_timer_ns/' \
        $(git grep -l 'qemu_new_timer\>' )

after checking that get_clock and new_timer never occur twice
on the same line.  There were no missed occurrences; however, even
if there had been, they would have been caught by the compiler.

There was exactly one false positive in qemu_run_timers:

     -    current_time = qemu_get_clock (clock);
     +    current_time = qemu_get_clock_ns (clock);

which is of course not in this patch.
