Subject: [PATCH AUTOSEL 5.13 054/219] drm/amd/amdgpu: Update debugfs link_settings output link_rate field in hex
Date: Thu, 9 Sep 2021 07:43:50 -0400 [thread overview]
Message-ID: <20210909114635.143983-54-sashal@kernel.org> (raw)
In-Reply-To: <20210909114635.143983-1-sashal@kernel.org>
From: Anson Jacob <Anson.Jacob@amd.com>
[ Upstream commit 1a394b3c3de2577f200cb623c52a5c2b82805cec ]
link_rate is updated via debugfs using hex values, set it to output
in hex as well.
eg: Resolution: 1920x1080@144Hz
cat /sys/kernel/debug/dri/0/DP-1/link_settings
Current: 4 0x14 0 Verified: 4 0x1e 0 Reported: 4 0x1e 16 Preferred: 0 0x0 0
echo "4 0x1e" > /sys/kernel/debug/dri/0/DP-1/link_settings
cat /sys/kernel/debug/dri/0/DP-1/link_settings
Current: 4 0x1e 0 Verified: 4 0x1e 0 Reported: 4 0x1e 16 Preferred: 4 0x1e 0
