[Qemu-devel] [PATCH v4 0/4] i386: expose floppy-related objects in SSDT

[Roman Kagan <rkagan@virtuozzo.com>]

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 the last patch of the series; the three
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 50/74] 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 (4):
  i386/pc: expose identifying the floppy controller
  i386/acpi: make floppy controller object dynamic
  expose floppy drive geometry and CMOS type
  i386: populate floppy drive information in SSDT

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
