2023-01-26habanalabs: move driver to accel subsystemOded Gabbay100-81039/+0
Now that we have a subsystem for compute accelerators, move the habanalabs driver to it. This patch only moves the files and fixes the Makefiles. Future patches will change the existing code to register to the accel subsystem and expose the accel device char files instead of the habanalabs device char files. Update the MAINTAINERS file to reflect this change. Signed-off-by: Oded Gabbay <ogabbay@kernel.org>

2022-02-28habanalabs/gaudi: add missing handling of NIC related eventsOded Gabbay1-0/+10

2022-02-17treewide: Replace zero-length arrays with flexible-array membersGustavo A. R. Silva1-2/+2
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.

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.

2021-06-18habanalabs/gaudi: use scratchpad regs instead of GIC controllerKoby Elbaz1-0/+6
Due to new security restrictions, GIC controller can no longer be accessed from user/kernel. To monitor that, a new status bit will be read from preboot caps, indicating whether direct access to GIC is blocked. In case it is blocked, driver will use scratchpad registers instead of using GIC interface on two main scenarios: The first of which LKD triggers interrupts to F/W through GIC, and the second of when LKD configures all engines/QMANs to write to GIC when they want to report an error. From F/W perspective, it will poll on all SPs, and once IRQ number is retrieved, SP register is cleared, and it will perform the write to the GIC to trigger the IRQ handler.

2020-07-24habanalabs: halt device CPU only upon certain resetOded Gabbay2-0/+4
Currently the driver halts the device CPU in the halt engines function, which halts all the engines of the ASIC. The problem is that if later on we stop the reset process (due to inability to clean memory mappings in time), the CPU will remain in halt mode. This creates many issues, such as thermal/power control and FLR handling. Therefore, move the halting of the device CPU to the very end of the reset process, just before writing to the registers to initiate the reset. In addition, the driver now needs to send a message to the device F/W to disable it from sending interrupts to the host machine because during halt engines function the driver disables the MSI/MSI-X interrupts.
