ahci: print the number of implemented ports (2024-02-21 19:13:43 +0100)
----------------------------------------------------------------
ata changes for 6.9-rc1
- Do not enable LPM for external ports (hotplug-capable ports or eSATA
ports), as the HBA will not be able to detect hot plug removal events
when LPM is enabled. (from me)
- Drop the board type board_ahci_low_power. Now when we make sure that we
won't enable LPM for external ports, we can always set the LPM policy to
CONFIG_SATA_MOBILE_LPM_POLICY for internal ports. There is thus no
longer any need for the board type board_ahci_low_power, so it can be
removed. (As before, LPM features not supported by the HBA and/or the
device will not be enabled, regardless of the LPM policy Kconfig.)
(from Mario Limonciello)
Note that the default CONFIG_SATA_MOBILE_LPM_POLICY value is still 0
(which will not try to enable any LPM features), however, most Linux
distributions override this and set it to 3 (Medium power with DIPM).
We intend to change the default to 3 in the coming cycles, but we will
wait a cycle or two.
- Add board type board_ahci_pcs_quirk and make all legacy Intel platforms
use it. The Intel PCS quirk was being applied to basically all Intel
platforms, which caused some issues (the device failing to come back
after a reset), when being applied to newer Intel platforms where it
shouldn't have been applied. Add board type board_ahci_pcs_quirk and
make legacy Intel platforms use it. New platforms can be added using
board type board_ahci (which will not have the quirk applied).
(from me)
- Rename board_ahci_nosntf to board_ahci_pcs_quirk_no_sntf to more clearly
highlight that it applies two different quirks. (from me)
- Modify the ahci_broken_devslp() quirk to be implemented like all the
other quirks (i.e. define a board type for the quirk). (from me)
- Drop unused board_ahci_noncq board type. (from me)
- Rename board_ahci_nomsi to board_ahci_no_msi to match the other board
types. (from me)
- Make pata_parport_bus_type const. (from Ricardo B. Marliere)
- Remove at91 compact flash device tree binding. (The binding is not used
by any driver.) (from Hari Prasath Gujulan Elango)
- Convert MediaTek device tree binding to json-schema.
(from Rafał Miłecki)
- At boot, print the number of implemented ports, instead of printing the
maximum number of ports supported by the HBA silicon. (from me)
