habanalabs/gaudi: add debugfs to fetch internal sync status

2022-05-22T18:57:37+00:00

When Gaudi device is secured the monitors data in the configuration space is blocked from PCI access. As we need to enable user to get sync-manager monitors registers when debugging, this patch adds a debugfs that dumps the information to a binary file (blob). When a root user will trigger the dump, the driver will send request to the f/w to fill a data structure containing dump of all monitors registers.

habanalabs: convert all MMU masks/shifts to arrays

2022-05-22T18:57:34+00:00

There is no need to hold each MMU mask/shift as a denoted structure member (e.g. hop0_mask). Instead converting it to array will result in smaller and more readable code. Signed-off-by: Ohad Sharabi Reviewed-by: Oded Gabbay Signed-off-by: Oded Gabbay Signed-off-by: Greg Kroah-Hartman

habanalabs/gaudi: add missing handling of NIC related events

2022-02-28T12:22:05+00:00

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

2022-02-17T13:00:39+00:00

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: add CPU-CP packet for engine core ASID cfg

2021-12-26T12:39:53+00:00

In some cases the driver cannot configure ASID of some engines due to the security level of the relevant registers. For this a new CPU-CP packet is introduced, which will allow the driver to ask the F/W to do this configuration instead.

habanalabs: clean MMU headers definitions

2021-12-26T06:59:09+00:00

During the MMU development the MMU header files were left with unclean definitions: - MMU "version specific" definitions that were left in the mmu_general file - unused definitions This patch attempts, where possible, to keep definitions that can serve multiple MMU versions (but that are not tightly bound with specific MMU arch) in the mmu_general header file (e.g. different definitions for number of HOPs). Otherwise, move MMU version specific definitions (e.g. HOPs masks and shifts) to the specific MMU version file. Signed-off-by: Ohad Sharabi Reviewed-by: Oded Gabbay Signed-off-by: Oded Gabbay
