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.

(In the future, we can pass the bootindex through "bootdevices" instead "bootorder" - unifying all bootdevice information in one fw_cfg value) The PV interface through fw_cfg could have also been implemented using device specific keys, e.g.: "/etc/bootdevice/%s/logical_geometry" where %s is the device name QEMU produces - but this implementation would require much more code refactoring, both in QEMU and SeaBIOS, so the current implementation was chosen.

QTest's fw_cfg helper functions support only legacy fw_cfg, so I had to read the new fw_cfg layout on my own. Creating qcow2 disks with specific size and MBR layout is currently unused - we only use a default empty MBR.

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: Rename bootdevices fw_cfg key to bios-geoemtry Sam Eiderman (5): geometry: Read LCHS from fw_cfg boot: Reorder functions in boot.c geometry: Add boot_lchs_find_*() utility functions config: Add toggle for bootdevice information geometry: Apply LCHS values for boot devices src/Kconfig | 7 ++ src/block.c | 21 ++++- src/block.h | 1 + src/boot.c | 244 +++++++++++++++++++++++++++++++++++++++++---------- src/hw/ahci.c | 1 + src/hw/ata.c | 8 ++ src/hw/esp-scsi.c | 2 + src/hw/lsi-scsi.c | 2 + src/hw/megasas.c | 1 + src/hw/mpt-scsi.c | 2 + src/hw/pvscsi.c | 1 + src/hw/virtio-blk.c | 2 + src/hw/virtio-scsi.c | 2 + src/util.h | 6 ++ 14 files changed, 254 insertions(+), 46 deletions(-) -- 2.13.3 _______________________________________________ SeaBIOS mailing list -- seabios@seabios.org To unsubscribe send an email to seabios-leave@seabios.org Read bios geometry for boot devices from fw_cfg. By receiving LCHS values directly from QEMU through fw_cfg we will be able to support logical geometries which can not be inferred by SeaBIOS itself. (For instance: A 8GB virtio-blk hard drive which was originally created as an IDE and must report LCHS of */32/63 for its operating system to function will always break under SeaBIOS since a LARGE/LBA translation will be used, causing the number of reported logical heads to be > 32.) The only LCHS paravirtual interface available at the moment is for IDE disks (rtc_read() in get_translation()) and it's limited to a maximum of 4 disks (this code existed in SeaBIOS's translation function before SCSI and VirtIO were even introduced). This is why we create a new interface which allows passing LCHS information per hdd. Boot device information is serialized in the following way: * device path (sz string) * device lchs ... * device path (sz string) * device lchs Device path is a null terminated string in the "Open Firmware" device path format, the same path as used in bootorder.
