* habanalabs/gaudi: add debugfs to fetch internal sync statusOhad Sharabi2022-05-221-0/+38
| | | | | | | | | | | | | | | | 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.

* | treewide: Replace zero-length arrays with flexible-array membersGustavo A. R. Silva2022-02-171-3/+3
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: create static map of f/w hwmon enumsRajaravi Krishna Katta2021-10-181-0/+6
| | | | | | | | | | | | | | | | | | Instead of using the Linux kernel HWMON enums definition when communicating with the firmware, use proprietary HWMON based enums i.e. map hwmon.h header enum to cpucp_if.h based enum while. This is needed because the HWMON enums are not forcing backward compatibility and therefore changes can break compatibility between newer driver and older firmware. The driver will check for CPU_BOOT_DEV_STS0_MAP_HWMON_EN bit to validate if f/w supports cpucp->hwmon enum mapping to support older firmware where this mapping won't be available.

* habanalabs/gaudi: read GIC sts after FW is loadedKoby Elbaz2021-06-181-2/+8
| | | | | | | | | | | | | | | | | | Reading of GIC privileged status will be done after F/W is loaded, because privileged GIC capability is only available with the correct ARMCP version, and after it's loaded. Such versions necessarily support COMMS, so GIC alternatives (SP regs) will be read directly from dynamic regs. As well, initiation of DMA QMANs will occur after F/W is loaded since it depends on GIC configuration. In case F/W isn't loaded there's no problem since either way there won't be any GIC IRQ handling.

* habanalabs/gaudi: use scratchpad regs instead of GIC controllerKoby Elbaz2021-06-181-0/+7
| | | | | | | | | | | | | | | | | | | | | 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.
