habanalabs/goya: move dma direction enum to uapi file

2022-07-12T06:09:25Z

The values in this enum are not used by h/w but are a contract between userspace and the kernel driver so they must be defined in the uapi file. Signed-off-by: Oded Gabbay

treewide: Replace zero-length arrays with flexible-array members

2022-02-17T13:00:39Z

There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2]. This code was transformed with the help of Coccinelle: (next-20220214$ spatch --jobs $(getconf _NPROCESSORS_ONLN) --sp-file script.cocci --include-headers --dir . > output.patch) @@ identifier S, member, array; type T1, T2; @@ struct S { ... T1 member; T2 array[ - 0 ]; }; UAPI and wireless changes were intentionally excluded from this patch and will be sent out separately.

habanalabs: support legacy and new pll indexes

2021-04-09T11:09:24Z

In order to use minimum of hard coded values common to LKD and F/W a dynamic method to work with PLLs is introduced in this patch. Formerly asic specific PLL numbering is now common for all asics. To be backward compatible a bit in dev status is defined, if the bit is not set LKD will keep working with old PLL numbering.
