scsi: switch ->bios_param() to passing gendisk

2025-08-13T06:59:28+00:00

Instances are passed struct block_device *bdev argument; the only thing it is used for (if it's used in the first place) is bdev->bd_disk. Might as well pass that in the first place... Reviewed-by: Martin K. Petersen Reviewed-by: Christoph Hellwig Acked-by: Jens Axboe Signed-off-by: Al Viro

scsi: make ppa depend on !HIGHMEM

2025-05-05T19:22:39+00:00

This is one of the last drivers depending on the block layer bounce buffering code. Restrict it to run on non-highmem configs so that the bounce buffering code can be removed.

Pull char / misc and other driver updates from Greg KH: "Here is the "big" set of char/misc and other driver subsystem changes for 6.11-rc1. Nothing major in here, just loads of new drivers and updates. Included in here are: - IIO api updates and new drivers added - wait_interruptable_timeout() api cleanups for some drivers - MODULE_DESCRIPTION() additions for loads of drivers - parport out-of-bounds fix - interconnect driver updates and additions - mhi driver updates and additions - w1 driver fixes - binder speedups and fixes - eeprom driver updates - coresight driver updates - counter driver update - new misc driver additions - other minor api updates All of these, EXCEPT for the final Kconfig build fix for 32bit systems, have been in linux-next for a while with no reported issues.

scsi: core: Add a no_highmem flag to struct Scsi_Host

2024-04-12T01:37:48+00:00

While we really should be killing the block layer bounce buffering ASAP, I even more urgently need to stop the drivers to fiddle with the limits from ->slave_configure. Add a no_highmem flag to the Scsi_Host to centralize this setting and switch the remaining four drivers that use block layer bounce buffering to it.

scsi: ppa: Add a module parameter for the transfer mode

2023-08-21T20:32:40+00:00

I have an Iomega Z100P2 zip drive, but it does not work with my StarTech PEX1P2 AX99100 PCIe parallel port, which evidently does not support 16-bit or 32-bit EPP. Currently the only way to tell the PPA driver to use 8-bit EPP is to write 'mode=3' to /proc/scsi/ppa/*, but the driver doesn't actually distinguish between the three EPP modes and still tries to use 16-bit or 32-bit EPP. And even if writing to that file did make the driver use 8-bit EPP, it still wouldn't do me any good because by the time that file exists, the drive has already failed to initialize. Add a new parameter /sys/module/ppa/mode to set the transfer mode before initializing the drive. This parameter replaces the use of CONFIG_SCSI_IZIP_EPP16 in the PPA driver. At the same time, default to 8-bit EPP. 16-bit and 32-bit EPP are not necessary for the drive to function, nor are they part of the IEEE 1284 standard, so the driver should not assume that they are available.
