platform/mellanox: NVSW_SN2201 should depend on ACPI

2023-09-11T11:21:46+00:00

The only probing method supported by the Nvidia SN2201 platform driver
is probing through an ACPI match table.  Hence add a dependency on
ACPI, to prevent asking the user about this driver when configuring a
kernel without ACPI support.

platform/mellanox: mlxbf-bootctl: add NET dependency into Kconfig

2023-09-11T11:13:25+00:00

The latest version of the mlxbf_bootctl driver utilizes
"sysfs_format_mac", and this API is only available if
NET is defined in the kernel configuration. This patch
changes the mlxbf_bootctl Kconfig to depend on NET.

platform/mellanox: mlxbf-pmc: Fix reading of unprogrammed events

2023-09-11T11:13:24+00:00

This fix involves 2 changes:
 - All event regs have a reset value of 0, which is not a valid
   event_number as per the event_list for most blocks and hence seen
   as an error. Add a "disable" event with event_number 0 for all blocks.

 - The enable bit for each counter need not be checked before
   reading the event info, and hence removed.

platform/mellanox: mlxbf-tmfifo: Drop the Rx packet if no more descriptors

2023-09-11T11:13:01+00:00

This commit fixes tmfifo console stuck issue when the virtual
networking interface is in down state. In such case, the network
Rx descriptors runs out and causes the Rx network packet staying
in the head of the tmfifo thus blocking the console packets. The
fix is to drop the Rx network packet when no more Rx descriptors.
Function name mlxbf_tmfifo_release_pending_pkt() is also renamed
to mlxbf_tmfifo_release_pkt() to be more approperiate.
