42 hourskernel: ahci: Lower link wait time to 8 msIan Moffett
Section 3.3.11 of the AHCI spec states that software must leave the DET field set for a minimum of 1 milisecond. Most hardware conforms to this. Previously, our buffer time was way too high and would slow down the time it takes for the AHCI driver to finish initialization. If any SATA drive takes longer than this to start up, fuck it, something is wrong with it. Signed-off-by: Ian Moffett <ian@osmora.org>
5 dayskernel: driver: Assign names to all driversIan Moffett
Assign a name to each driver through the DRIVER_EXPORT() or DRIVER_DEFER() macros. This can be used for blacklisting driver startups. Signed-off-by: Ian Moffett <ian@osmora.org>

This is no longer needed as the Hyra PMM now does this automatically by default. Signed-off-by: Ian Moffett <ian@osmora.org>

2025-06-10kernel: ahci: Fix issue of undetectable devicesIan Moffett
- Only check PxSCTL.SET within the port reset logic - Do not create device file for ATAPI devices (yet) Signed-off-by: Ian Moffett <ian@osmora.org>
2025-06-10kernel: ahci: Improve port reset logicIan Moffett
- Set PxCMD.SUD if the HBA supports staggered spin-up to ensure the device will be detectable. - Wait for the device link to be established - Detect and log SATA link speed Signed-off-by: Ian Moffett <ian@osmora.org>
