This is used by the graph compiler to accurately measure the time it takes for certain workloads to execute, which helps to fine-tune future compilations. - Add two new attributes to sysfs that expose the VRM and f/w OS version - Add a delay to the reset path that allows the driver to receive and handle additional events from the f/w before doing the reset. This can help when debugging why a reset event was received from the f/w. - Re-factor some of the sysfs code in the driver. Mainly, move functions from hwmgr.c to more relevant files and totally remove hwmgr.c file. - Fix multiple bugs such as races, use-after-free, ignoring error codes, etc. - As usual, multiple minor changes and small fixes. * tag 'misc-habanalabs-next-2022-02-28' of https://git.kernel.org/pub/scm/linux/kernel/git/ogabbay/linux: (50 commits) habanalabs: remove deprecated firmware states habanalabs: add an option to delay a device reset habanalabs: Add check for pci_enable_device habanalabs: Fix reset upon device release bug habanalabs: make sure device mem alloc is page aligned habanalabs/gaudi: add missing handling of NIC related events habanalabs/gaudi: handle axi errors from NIC engines habanalabs: allow user to set allocation page size habanalabs: use kernel-doc for memory ioctl documentation habanalabs: avoid using an uninitialized variable habanalabs: set max power on device init per ASIC habanalabs: use proper max_power variable for device utilization habanalabs: enable stop-on-error debugfs setting per ASIC habanalabs: change function to static habanalabs: add missing include of vmalloc.h habanalabs: fix use-after-free bug habanalabs: rephrase error messages in PCI initialization habanalabs: fix spelling mistake habanalabs: Timestamps buffers registration habanalabs: fix race when waiting on encaps signal ...

Booting msm8939 on tip-of-tree I encountered the following error. [ 1.212340] qnoc-msm8939 580000.interconnect_mm: can't request region for resource [mem 0x00580000-0x0059407f] [ 1.212391] qnoc-msm8939 580000.interconnect_mm: Cannot ioremap interconnect bus resource [ 1.221524] qnoc-msm8939: probe of 580000.interconnect_mm failed with error -16 Initially I thought this was a bug with the interconnect driver but, examining it a bit more I realized the DTS I was working with based on downstream, declares snoc and snoc_mm as existing at the same address range. When we were developing the DTS for 8939 we weren't using the common rpm interconnect driver so we never saw the ioremap collision. Taking a hard look at the qcom documentation as well as the downstream code we see that yes downstream declares snoc and snoc_mm separately but, also at the same overlapping address. The qcom documentation for performance points for msm8936/msm8939 snoc, deliniates snoc_mm as simply two new performance-points i.e. a faster GPLL0 vote associated with new multi-media devices attached to the snoc. In other words the snoc had two new RPM vote indices added to it, to represent the higher performance clocks, should one of the multi-media IP blocks call for it. We can fix the ioremap collision and still represent the two higher performance point clock votes by coalsecing snoc and snoc_mm into snoc. The DTS clock references will take care of the appropriate votes.

Several H/W events can be sent adjacently, even due to a single error. If a hard-reset is triggered as part of handling one of these events, the following events won't be handled. The debug info from these missed events is important, sometimes even more important than the one that was handled. To allow handling these close events, add an option to delay a device reset and use it when resetting due to H/W events. Signed-off-by:

In case user application was interrupted while some cs still in-flight or in the middle of completion handling in driver, the last refcount of the kernel private data for the user process will not be put in the fd close flow, but in the cs completion workqueue context. This means that the device reset-upon-device-release will be called from that context. During the reset flow, the driver flushes all the cs workqueue to ensure that any scheduled work has run to completion, and since we are running from the completion context we will have deadlock. Therefore, we need to skip flushing the workqueue in those cases. It is safe to do it because the user won't be able to release the device unless the workqueues are already empty. Signed-off-by:

Working with MMU that supports multiple page sizes requires that mapping of a page of a certain size will be aligned to the same size (e.g. the physical address of 32MB page shall be aligned to 32MB).

Ohad Sharabi authored
In future ASICs the MMU will be able to work with multiple page sizes, thus a new flag is added to allow the user to set the requested page size. This flag is added since the whole DRAM is allocated for the user and the user also should be familiar with the memory usage use case. As such, the user may choose to "over allocate" memory in favor of performance (for instance- large page allocations covers more memory in less TLB entries). For example: say available page sizes are of 1MB and 32MB. If user wants to allocate 40MB the user can either set page size to 1MB and allocate the exact amount of memory (but will result in 40 TLB entries) or the user can use 32MB pages, "waste" 8MB of physical memory but occupy only 2 TLB entries. Note that this feature will be available only to ASIC that supports multiple DRAM page sizes. Signed-off-by:

For current devices there is a need to send the max power value to F/W during device init, for example because there might be several card types.
