Subject: RE: [RFC PATCH 2/2] mmc: Allow tuning to be skipped during card init
Date: Tue, 28 Jan 2025 16:20:18 -0600 [thread overview]
Message-ID: <20250128222018.295627-1-erick.shepherd@ni.com> (raw)

I have been working with a DDR50 SD card that does not support tuning.
The card's first tuning attempt fails, which is expected, but subsequent
tuning attempts cause I/O errors due to async page reads. My first patch
mostly solves this issue but I was still seeing I/O errors in the case
where the card is reset and attempts to do the initial tuning again
despite it failing previously. This second patch allows the initial tuning
to be skipped if it has already failed for a DDR50 card.
