[SeaBIOS] [QEMU] [PATCH 8/8] hd-geo-test: Add tests for lchs override
Posted by Sam Eiderman 5 years, 1 month ago
Add QTest tests to check the logical geometry override option.

The tests in hd-geo-test are out of date - they only test IDE and do not
test interesting MBRs.

I added a few helper functions which will make adding more tests easier.

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.
