habanalabs/gaudi: add missing handling of NIC related events

2022-02-28T12:22:05Z

There are a few events that can arrive from the f/w and without proper handling can cause errors to appear in the kernel log without reason. Add the relevant handling that was missing. 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/gaudi: use direct MSI in single mode

2021-09-14T12:00:03Z

Due to FLR scenario when running inside a VM, we must not use indirect MSI because it might cause some issues on VM destroy. In a VM we use single MSI mode in contrary to multi MSI mode which is used in bare-metal. Hence direct MSI should be used in single MSI mode only.

habanalabs/gaudi: correct driver events numbering

2021-06-18T12:23:42Z

Currently driver sends fc interrupt id to FW instead of using cpu interrupt id. We intend to fix that and keep backward compatibility by using the same interrupt values. Signed-off-by: Ofir Bitton Reviewed-by: Oded Gabbay Signed-off-by: Oded Gabbay
