2021-10-18habanalabs: fix race condition in multi CS completionDani Liberman2-1/+23
Race condition occurs when CS fence completes and multi CS did not completed yet, while waiting for multi CS ends and returns indication to user that the CS completed. Next wait for multi CS may be triggered by previous multi CS completion without any current CS completed, causing an error. Example scenario : 1. User do multi CS wait for CSs 1 and 2 on master QID 0 2. CS 1 and 2 reached the "cs release" code. The thread of CS 1 completed both the CS and multi CS handling but the completion thread of CS 2 completed the CS but still did not executed complete_multi_cs (note that in CS completion the sequence is to first do complete all for the CS and then another complete all to signal the multi_cs) 3. User received indication that CS 1 and 2 completed (since we check the CS fence and both indicated as completed) and immediately waits on CS 3 and 4, also on master QID 0. 4. Completion thread of CS2 executed complete_multi_cs before completion of CS 3 and 4 and so will trigger the multi CS wait of CSs 3 and 4 as they wait on master QID 0. This will trigger multi CS completion although none of its current CS has been completed. Fixed by adding multi CS complete handling indication for each CS. CS will be marked to the user as completed only if its fence completed and multi CS handling is done.

2021-10-18habanalabs: bypass reset for continuous h/w error eventBharat Jauhari5-36/+111
There may be a situation where drivers receives continuous fatal H/W error events from FW immediately post reset cycle. This may be due to some fault on the silicon itself. In such case its better to bypass reset cycle so we won't be stuck in endless loop of resets. This commit bypasses reset request in case driver received two back to back FW fatal error before first occurrence of heartbeat event.

2021-10-18habanalabs: prevent race between fd close/openOded Gabbay1-7/+23
The driver allows only a single process to open a device's FD at any single time. This is done by checking "hdev->compute_ctx" under mutex. Therefore, to prevent a race between the moment a user closes it's FD and when another user tries to open the device, we need to make sure that clearing this variable is the very last thing that is done in the code of the FD's release. I'm moving the idle check before clearing this variable and the "reset on device release". btw, if the reset happens it will prevent any other user from opening the device until the reset is finished. An important thing to note is that we need to remove the user process that is closing the device from the process list BEFORE calling the reset function. That is to prevent a case where the reset code will try to kill that user process and it is unnecessary as the process doesn't hold any device/driver resources anymore.

2021-10-18habanalabs: refactor reset log messageOded Gabbay1-1/+8
Reset to the device is not necessarily due to an error, so print it as info instead of error. In addition, print the type of reset we are doing: - reset of the entire device (aka hard reset) - reset of the device after user have released it (less than hard reset) - lighter reset of an inference device (aka soft reset) Signed-off-by: Oded Gabbay <ogabbay@kernel.org>
2021-10-18habanalabs: define soft-reset as inference opOded Gabbay4-8/+12
Soft-reset is the procedure where we reset only the compute/DMA engines of the device, without requiring the current user-space process to release the device. This type of reset can happen if TDR event occurred (a workload got stuck) or by a root request through sysfs. This is only relevant for inference ASICs, as there is no real-world use-case to do that in training, because training runs on multiple devices. In addition, we also do (in certain ASICs) a reset upon device release. That reset uses the same code as the soft-reset. Therefore, to better differentiate between the two resets, it is better to rename the soft-reset support as "inference soft-reset", to make the code more self-explanatory.

2021-10-18habanalabs: create static map of f/w hwmon enumsRajaravi Krishna Katta2-9/+97
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.

2021-10-17block, bfq: reset last_bfqq_created on group changePaolo Valente1-0/+6
Since commit 430a67f9d616 ("block, bfq: merge bursts of newly-created queues"), BFQ maintains a per-group pointer to the last bfq_queue created. If such a queue, say bfqq, happens to move to a different group, then bfqq is no more a valid last bfq_queue created for its previous group. That pointer must then be cleared. Not resetting such a pointer may also cause UAF, if bfqq happens to also be freed after being moved to a different group. This commit performs this missing reset. As such it fixes commit 430a67f9d616 ("block, bfq: merge bursts of newly-created queues"). Such a missing reset is most likely the cause of the crash reported in [1]. With some analysis, we found that this crash was due to the above UAF. And such UAF did go away with this commit applied [1]. Anyway, before this commit, that crash happened to be triggered in conjunction with commit 2d52c58b9c9b ("block, bfq: honor already-setup queue merges"). The latter was then reverted by commit ebc69e897e17 ("Revert "block, bfq: honor already-setup queue merges""). Yet commit 2d52c58b9c9b ("block, bfq: honor already-setup queue merges") contains no error related with the above UAF, and can then be restored.

2021-10-16x86/fpu: Mask out the invalid MXCSR bits properlyBorislav Petkov1-1/+1
This is a fix for the fix (yeah, /facepalm). The correct mask to use is not the negation of the MXCSR_MASK but the actual mask which contains the supported bits in the MXCSR register.

2021-10-16Input: touchscreen - avoid bitwise vs logical OR warningNathan Chancellor1-21/+21
A new warning in clang points out a few places in this driver where a bitwise OR is being used with boolean types: drivers/input/touchscreen.c:81:17: warning: use of bitwise '|' with boolean operands [-Wbitwise-instead-of-logical] data_present = touchscreen_get_prop_u32(dev, "touchscreen-min-x", ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This use of a bitwise OR is intentional, as bitwise operations do not short circuit, which allows all the calls to touchscreen_get_prop_u32() to happen so that the last parameter is initialized while coalescing the results of the calls to make a decision after they are all evaluated. To make this clearer to the compiler, use the '|=' operator to assign the result of each touchscreen_get_prop_u32() call to data_present, which keeps the meaning of the code the same but makes it obvious that every one of these calls is expected to happen.
