Subject: [net-next V2 13/15] net/mlx5: DR, Change SWS usage to debug fs seq_file interface
Date: Wed, 31 Jan 2024 23:31:56 -0800 [thread overview]
Message-ID: <20240201073158.22103-14-saeed@kernel.org> (raw)
In-Reply-To: <20240201073158.22103-1-saeed@kernel.org>
From: Hamdan Igbaria <hamdani@nvidia.com>
In current SWS debug dump mechanism we implement the seq_file interface,
but we only implement the 'show' callback to dump the whole steering DB
with a single call to this callback.
However, for large data size the seq_printf function will fail to
allocate a buffer with the adequate capacity to hold such data.
This patch solves this problem by utilizing the seq_file interface
mechanism in the following way:
- when the user triggers a dump procedure, we will allocate a list of
buffers that hold the whole data dump (in the start callback)
- using the start, next, show and stop callbacks of the seq_file
API we iterate through the list and dump the whole data
