[SeaBIOS] [QEMU] [PATCH v4 0/8] Add Qemu to SeaBIOS LCHS interface

Posted by Sam Eiderman 8 weeks ago
v1:

Non-standard logical geometries break under QEMU.

A virtual disk which contains an operating system which depends on
logical geometries (consistent values being reported from BIOS INT13
AH=08) will most likely break under QEMU/SeaBIOS if it has non-standard
logical geometries - for example 56 SPT (sectors per track).
No matter what QEMU will guess - SeaBIOS, for large enough disks - will
use LBA translation, which will report 63 SPT instead.

In addition we can not enforce SeaBIOS to rely on phyiscal geometries at
all. A virtio-blk-pci virtual disk with 255 phyiscal heads can not
report more than 16 physical heads when moved to an IDE controller, the
ATA spec allows a maximum of 16 heads - this is an artifact of
virtualization.

By supplying the logical geometies directly we are able to support such
"exotic" disks.

We will use fw_cfg to do just that.

v2:

Fix missing parenthesis check in
    "hd-geo-test: Add tests for lchs override"

v3:

* Rename fw_cfg key to "bios-geometry".
* Remove "extendible" interface.
* Add cpu_to_le32 fix as Laszlo suggested or big endian hosts
* Fix last qtest commit - automatic docker tester for some reason does not have qemu-img set

v4:

* Change fw_cfg interface from mixed textual/binary to textual only

Sam Eiderman (8):
  block: Refactor macros - fix tabbing
  block: Support providing LCHS from user
  bootdevice: Add interface to gather LCHS
  scsi: Propagate unrealize() callback to scsi-hd
  bootdevice: Gather LCHS from all relevant devices
  bootdevice: Refactor get_boot_devices_list
  bootdevice: FW_CFG interface for LCHS values
  hd-geo-test: Add tests for lchs override
