From: Jiri Pirko <j...@mellanox.com> When user is flashing device using devlink, he currenly does not see any information about what is going on, percentages, etc. Drivers, for example mlxsw and mlx5, have notion about the progress and what is happening. This patchset exposes this progress information to userspace.
Example output for existing flash command: $ devlink dev flash pci/0000:01:00.0 file firmware.bin Preparing to flash Flashing 100% Flashing done See this console recording which shows flashing FW on a Mellanox Spectrum device: https://asciinema.org/a/247926 --- Please see individual patches for changelog. Jiri Pirko (7): mlxsw: Move firmware flash implementation to devlink mlx5: Move firmware flash implementation to devlink mlxfw: Propagate error messages through extack devlink: allow driver to update progress of flash update mlxfw: Introduce status_notify op and call it to notify about the status mlxsw: Implement flash update status notifications netdevsim: implement fake flash updating with notifications drivers/net/ethernet/mellanox/mlx5/core/en.h | 2 - .../ethernet/mellanox/mlx5/core/en_ethtool.c | 35 ------ drivers/net/ethernet/mellanox/mlx5/core/fw.c | 6 +- .../mellanox/mlx5/core/ipoib/ethtool.c | 9 -- .../net/ethernet/mellanox/mlx5/core/main.c | 20 ++++ .../ethernet/mellanox/mlx5/core/mlx5_core.h | 3 +- drivers/net/ethernet/mellanox/mlxfw/mlxfw.h | 11 +- .../net/ethernet/mellanox/mlxfw/mlxfw_fsm.c | 57 ++++++++-- drivers/net/ethernet/mellanox/mlxsw/core.c | 15 +++ drivers/net/ethernet/mellanox/mlxsw/core.h | 3 + .../net/ethernet/mellanox/mlxsw/spectrum.c | 75 +++++++------ drivers/net/netdevsim/dev.c | 44 ++++++++ drivers/net/netdevsim/netdevsim.h | 1 + include/net/devlink.h | 8 ++ include/uapi/linux/devlink.h | 5 + net/core/devlink.c | 102 ++++++++++++++++++ 16 files changed, 305 insertions(+), 91 deletions(-) -- 2.17.2
