Hi all,
I'd like to replace jailhouse-cell-list. It's a rudimentary function and
requires python. So I reimplemented cell-list natively in C.
This series also changes the sysfs structure as Jan proposed.
Though in total we have more lines of C code, the hypervisor shrinked a bit.
I tested the code on a Jetson TK1 and Qemu VM. For me, it works so far.
Applies against next.
changes since v4:
- maintain Documentation/hypervisor-interfaces.txt
- rename read_sysfs_entry to read_sysfs_cell_string
and avoid repeating snprintf()'s
changes since v3:
- let the driver choose the cell ID
- use a filter function for scandir()
- remove jailhouse-cell-list from tools/Makefile
- adapt tools/jailhouse-completion.bash
- minor cosmetic changes
changes since v2:
- do not use struct jailhouse_cell_id inside struct cell
- adapt read_file() as suggested by Jan
- amend commit messages
- use scandir() and alphasort for sorted output
changes since v1:
- change sysfs structure (swap id and name)
- provide human readable sysfs nodes
- improve changes on read_file()
Ralf Ramsauer (9):
driver: cell: add cell name to struct cell
driver: sysfs: do not pass cell name to jh_sysfs_cell_create
hypervisor, driver: let the driver choose cell ids
driver: sysfs: swap sysfs entries name and id
driver: sysfs: consolidate cpumask printing
driver: sysfs: factor out printing of failed_cpus
driver: sysfs: add new sysfs nodes cpus_{assigned,failed}_list
tools: jailhouse: make read_file() compatible with sysfs files
tools: jailhouse: reimplement jailhouse-cell-list in C
