s390x: Fix spelling errors

2022-11-16T09:15:26+00:00

Fix typos (discovered with the 'codespell' utility). Note: Though "migrateable" still seems to be a valid spelling, we change it to "migratable" since this is the way more common spelling here.

pc-bios: s390x: Get rid of magic offsets into the lowcore

2020-07-02T07:59:51+00:00

If we have a lowcore struct that has members for offsets that we want to touch, why not use it? Signed-off-by: Janosch Frank Reviewed-by: David Hildenbrand Reviewed-by: Thomas Huth Reviewed-by: Cornelia Huck Message-Id: <20200624075226.92728-5-frankja@linux.ibm.com> Signed-off-by: Thomas Huth

s390-bios: Add channel command codes/structs needed for dasd-ipl

2019-04-12T10:40:35+00:00

The dasd IPL procedure needs to execute a few previously unused channel commands. Let's define them and their associated data structures. Signed-off-by: Jason J.

s390-bios: Support for running format-0/1 channel programs

2019-04-12T10:40:35+00:00

Introduce a library function for executing format-0 and format-1 channel programs and waiting for their completion before continuing execution. Add cu_type() to channel io library. This will be used to query control unit type which is used to determine if we are booting a virtio device or a real dasd device. Signed-off-by: Jason J.

s390-bios: Decouple channel i/o logic from virtio

2019-04-12T10:40:35+00:00

Create a separate library for channel i/o related code. This decouples channel i/o operations from virtio and allows us to make use of them for the real dasd boot path. Signed-off-by: Jason J.

pc-bios/s390-ccw: struct tpi_info must be declared as aligned(4)
