[Qemu-devel] [PATCH v5 0/6] i386: expose floppy-related objects in SSDT

[Roman Kagan]

Windows on UEFI systems is only capable of detecting the presence and
the type of floppy drives via corresponding ACPI objects.

Those objects are added in patch 5; the preceding ones pave the way to
it, by making the necessary data public and by moving the whole
floppy drive controller description into runtime-generated SSDT.

Note that the series conflicts with Igor's patchset for dynamic DSDT, in
particular, with "[PATCH v2 27/51] pc: acpi: move FDC0 device from DSDT
to SSDT"; I haven't managed to avoid that while trying to meet
maintainer's comments.

Roman Kagan (6):
  i386/pc: expose identifying the floppy controller
  i386/acpi: make floppy controller object dynamic
  tests/acpi: update test data
  expose floppy drive geometry and CMOS type
  i386: populate floppy drive information in SSDT
  tests/acpi: update test data

changes since v4:
 - re-split out code changes from test data updates

changes since v3:
 - make FDC object fully dynamic in a separate patch
 - split out support patches
 - include test data updates with the respective patches to maintain
   bisectability

changes since v2:
 - explicit endianness for buffer data
 - reorder code to reduce conflicts with dynamic DSDT patchset
 - update test data
