2021-06-18habanalabs: add debug flag to prevent failure on timeoutYuri Nudelman2-5/+25
Sometimes it is useful to allow the command to continue running despite the timeout occurred, to differentiate between really stuck or just very time consuming commands. This can be achieved by passing a new debug flag alongside the cs, HL_CS_FLAGS_SKIP_RESET_ON_TIMEOUT. Anyway, if the timeout occurred, a warning print shall be issued, however this shall not fail the submission.

2021-06-18habanalabs/gaudi: add FW alive event supportOfir Bitton4-1/+32
In order for driver to be aware of process or thread crashes inside GAUDI's CPU, we introduce a new event which contains all relevant information. Upon event reception, driver will dump information and will reset the device.

2021-06-18habanalabs/gaudi: don't use disabled ports in collective waitOfir Bitton1-148/+71
In the collective wait, we put jobs on the QMANs of all the NICs. The code takes into account if a port is disabled only in case of PCI card. When this info arrives from the f/w, the code doesn't take it into account, and it tries to schedule jobs on NICs that aren't enabled and thats a bug. To fix this, after the f/w sends us the list of disabled ports, we update the state of the QMANs according to that list. In addition, we need to update the HW_CAP bits so the collective wait operation will not try to use those QMANs. We also need to update the collective master monitor mask. Moreover, we need to add a protection for such future cases and in case the user will try to submit work to those QMANs.

2021-06-18habanalabs/gaudi: refactor reset codeOded Gabbay2-18/+34
After all the latest changes to the reset code, there were some redundancy and errors in the flows. If the Linux FIT is loaded to the ASIC CPU, we need to communicate with it only via GIC. If it is not loaded, we need to either use COMMS protocol (for newer f/w) or MSG_TO_CPU register (for older f/w). In addition, if we halted the device CPU then we need to mark that the driver will do the reset, regardless of the capabilities. Also, to prevent false errors, we need to keep track whether the device CPU was already halted. If so, we shouldn't try to halt it again. Signed-off-by: Oded Gabbay <[email protected]>

On newer releases, host won't be able to trigger an interrupt directly to the ASIC GIC controller.

2021-06-18habanalabs: check running index in eqe controlOded Gabbay5-5/+49
To harden the event queue mechanism, we add a running index to the control header of the entry. The firmware writes the index in each entry and the driver verifies that the index of the current entry is larger by 1 of the index of the previous entry. In case it isn't, the driver will treat the entry as if it wasn't valid (it won't process it but won't skip it). Signed-off-by: Oded Gabbay <[email protected]>

2021-06-18habanalabs/gaudi: read GIC sts after FW is loadedKoby Elbaz3-28/+57
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.

Current implementation is based on the new FW 'COMMS' protocol In cased 'COMMS' is disabled - reset cause won't be sent. Currently, only 2 reset causes are shared: HEARTBEAT & TDR.

2021-06-18habanalabs/gaudi: use scratchpad regs instead of GIC controllerKoby Elbaz6-36/+104
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.

2021-06-18habanalabs: expose ASIC specific PCI info to common codeOhad Sharabi4-0/+124
LKD has interfaces in which it receives device address. For instance the debugfs_read/write variants receives device address for CFG/SRAM/DRAM for read/write and need to translate to the mapped PCI BAR address. In addition, the dynamic FW load protocol dictates that the address to which the LKD will copy the image for the next FW component will be received as a device address and can be placed either in SRAM or DRAM. We need to distinguish those regions as the access methods to those regions are different (in DRAM we possibly need to set the BAR base). Looking forward this code will be used to remove duplicated code in the debugfs_read/write that search the memory region for the input device address.
