From: Matthew Gerlach <matthew.gerlach@xxxxxxxxxxxxxxx> Add the feature id of the OFS HSSI (High Speed Serial Interface) subsystem to table of ids supported by the uio_dfl driver. HSSI subsystem consists of harden/soft Ethernet MAC to support various ethernet usages and PCS/FEC/PMA direct modes for non-ethernet usages. We leverage the uio_dfl driver to access the HSSI subsystem on user space, because the HSSI subsystem was designed for specific purposes and does not fit into the standard MAC and net kernel subsystems. The Feature ID table of DFL can be found: https://github.com/OPAE/dfl-feature-id Signed-off-by: Matthew Gerlach <matthew.gerlach@xxxxxxxxxxxxxxx> Signed-off-by: Tianfei Zhang <tianfei.zhang@xxxxxxxxx> --- v2: add HSSI introduction and the git repo of Feature ID table. --- drivers/uio/uio_dfl.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/drivers/uio/uio_dfl.c b/drivers/uio/uio_dfl.c index 89c0fc7b0cbc..660e1d0bf6b9 100644 --- a/drivers/uio/uio_dfl.c +++ b/drivers/uio/uio_dfl.c @@ -45,9 +45,11 @@ static int uio_dfl_probe(struct dfl_device *ddev) } #define FME_FEATURE_ID_ETH_GROUP 0x10 +#define FME_FEATURE_ID_OFS_HSSI 0x15 static const struct dfl_device_id uio_dfl_ids[] = { { FME_ID, FME_FEATURE_ID_ETH_GROUP }, + { FME_ID, FME_FEATURE_ID_OFS_HSSI }, { } }; MODULE_DEVICE_TABLE(dfl, uio_dfl_ids); -- 2.26.2
