Subject: [PATCH] mmc: sdhci: Quirk for broken command queuing on Intel GLK-based Positivo models
Date: Thu, 26 Jun 2025 08:24:42 -0300 [thread overview]
Message-ID: <20250626112442.9791-1-edson.drosdeck@gmail.com> (raw)
Disable command queuing on Intel GLK-based Positivo models.
Without this quirk, CQE (Command Queuing Engine) causes instability
or I/O errors during operation. Disabling it ensures stable
operation on affected devices.
