[PATCH 3/3] hdio: improve HDIO support
Srikavin Ramkumar
srikavinramkumar at gmail.com
Sat Aug 21 13:52:00 UTC 2021
Add decoders for HDIO_GET_UNMASKINTR, HDIO_SET_UNMASKINTR,
HDIO_GET_MULTCOUNT, HDIO_SET_MULTCOUNT, HDIO_OBSOLETE_IDENTITY,
HDIO_GET_IDENTITY, HDIO_GET_KEEPSETTINGS, HDIO_SET_KEEPSETTINGS,
HDIO_GET_32BIT, HDIO_GET_NOWERR, HDIO_GET_DMA, HDIO_GET_NICE,
HDIO_SET_NICE, HDIO_GET_WCACHE, HDIO_GET_ACOUSTIC, HDIO_GET_ADDRESS,
HDIO_GET_BUSSTATE, HDIO_SET_BUSSTATE, and HDIO_DRIVE_RESET.
* maint/gendefs/hdio.def: New file.
* src/Makefile.am (libstrace_a_SOURCES): Add gen/generated.h and gen/gen_hdio.c.
* src/gen/gen_hdio.c: Add generated file.
* src/gen/generated.h: New file.
* src/hdio.c: Add call to generated file for unimplemented commands.
* src/xlat/hdio_busstates.in: New file.
* src/xlat/hdio_ide_nice.in: Likewise.
* tests/ioctl_hdio.c: Add tests for newly implemented commands.
