2019-04-22habanalabs: use ASIC functions interface for rreg/wregOded Gabbay
This patch slightly changes the macros of RREG32 and WREG32, which are used when reading or writing from registers. Instead of directly calling a function in the common code from these macros, the new code calls a function from the ASIC functions interface. This change allows us to share much more code between real ASICs and simulators, which in turn reduces the maintenance burden and the chances for forgetting to port code between the ASIC files. The patch also implements the hl_poll_timeout macro, instead of calling the generic readl_poll_timeout macro. This is required to allow use of this macro in the simulator files. As a result from this change, more functions in goya.c are shared with the simulator and therefore, should not be defined as static. Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com>
2019-04-21uapi/habanalabs: add missing fields in bmon paramsOded Gabbay
This patch adds missing fields of start address 0 and 1 in the bmon parameter structure that is received from the user in the debug IOCTL. Without these fields, the functionality of the bmon trace is broken, because there is no configuration of the base address of the filter of the bus monitor.

2019-04-10habanalabs: Cancel pr_fmt() definition dependency on includes orderTomer Tayar
pr_fmt() should be defined before including linux/printk.h, either directly or indirectly, in order to avoid redefinition of the macro. Currently the macro definition is in habanalabs.h, which is included in many files, and that makes the addition/reorder of includes to be prone to compilation errors. This patch cancels this dependency by defining the macro only in the few source files that use it. Signed-off-by: Tomer Tayar <ttayar@habana.ai> Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com>

2019-04-06habanalabs: prevent device PTE read/write during hard-resetOded Gabbay
During hard-reset, contexts are closed as part of the tear-down process. After a context is closed, the driver cleans up the page tables of that context in the device's DRAM. This action is both dangerous and unnecessary. It is unnecessary, because the device is going through a hard-reset, which means the device's DRAM contents are no longer valid and the device's MMU is being reset. It is dangerous, because if the hard-reset came as a result of a PCI freeze, this action may cause the entire host machine to hang. Therefore, prevent all device PTE updates when a hard-reset operation is pending. Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com>
2019-04-06habanalabs: improve IOCTLs behavior when disabled or resetOded Gabbay
This patch makes some improvement in how IOCTLs behave when the device is disabled or under reset. The new code checks, at the start of every IOCTL, if the device is disabled or in reset. If so, it prints an appropriate kernel message and returns -EBUSY to user-space. In addition, the code modifies the location of where the hard_reset_pending flag is being set or cleared: 1. It is now cleared immediately after the reset *tear-down* flow is finished but before the re-initialization flow begins. 2. It is being set in the remove function of the device, to make the behavior the same with the hard-reset flow There are two exceptions to the disable or in reset check: 1. The HL_INFO_DEVICE_STATUS opcode in the INFO IOCTL. This opcode allows the user to inquire about the status of the device, whether it is operational, in reset or malfunction (disabled). If the driver will block this IOCTL, the user won't be able to retrieve the status in case of malfunction or in reset. 2. The WAIT_FOR_CS IOCTL. This IOCTL allows the user to inquire about the status of a CS. We want to allow the user to continue to do so, even if we started a soft-reset process because it will allow the user to get the correct error code for each CS he submitted.

2019-04-06habanalabs: all FD must be closed before removing deviceOded Gabbay
This patch fixes a bug in the implementation of the function that removes the device. The bug can happen when the device is removed but not the driver itself (e.g. remove by the OS due to PCI freeze in Power architecture). In that case, there maybe open users that are calling IOCTLs while the device is removed. This is a possible race condition that the driver must handle. Otherwise, a kernel panic may occur. This race is prevented in the hard-reset flow, because the driver makes sure the users are closed before continuing with the hard-reset. This race can not occur when the driver itself is removed because the OS makes sure all the file descriptors are closed. The fix is to make sure the open users close their file descriptors and if they don't (after a certain amount of time), the driver sends them a SIGKILL, because the remove of the device can't be stopped. The patch re-uses the same code that is called from the hard-reset flow. Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com>
2019-04-04habanalabs: split mmu/no-mmu code paths in memory ioctlOded Gabbay

2019-04-04habanalabs: ASIC_AUTO_DETECT enum value is redundantOded Gabbay
This patch removes the enum value of ASIC_AUTO_DETECT because we can use the validity of the pdev variable to know whether we have a real device or a simulator. For a real device, we detect the asic type from the device ID while for a simulator, the simulator code calls create_hdev() with the specified ASIC type. Set ASIC_INVALID as the first option in the enum to make sure that no other enum value will receive the value 0 (which indicates a non-existing entry in the simulator array).

2019-04-01habanalabs: add goya implementation for debug configurationOmer Shpigelman
This patch adds the ASIC-specific function for GOYA to configure the coresight components. Most of the components have an enabled/disabled flag, depending on whether the user wants to enable the component or disable it. For some of the components, such as ETR and SPMU, the user can also request to read values from them. Those values are needed for the user to parse the trace data. The ETR configuration is also checked for security purposes, to make sure the trace data is written to the device's DRAM.

2019-04-01habanalabs: add new IOCTL for debug, tracing and profilingOmer Shpigelman
Habanalabs ASICs use the ARM coresight infrastructure to support debug, tracing and profiling of neural networks topologies. Because the coresight is configured using register writes and reads, and some of the registers hold sensitive information (e.g. the address in the device's DRAM where the trace data is written to), the user must go through the kernel driver to configure this mechanism. This patch implements the common code of the IOCTL and calls the ASIC-specific function for the actual H/W configuration. The IOCTL supports configuration of seven coresight components: ETR, ETF, STM, FUNNEL, BMON, SPMU and TIMESTAMP The user specifies which component he wishes to configure and provides a pointer to a structure (located in its process space) that contains the relevant configuration. The common code copies the relevant data from the user-space to kernel space and then calls the ASIC-specific function to do the H/W configuration. After the configuration is done, which is usually composed of several IOCTL calls depending on what the user wanted to trace, the user can start executing the topology. The trace data will be written to the user's area in the device's DRAM. After the tracing operation is complete, and user will call the IOCTL again to disable the tracing operation. The user also need to read values from registers for some of the components (e.g. the size of the trace data in the device's DRAM). In that case, the user will provide a pointer to an "output" structure in user-space, which the IOCTL code will fill according the to selected component.

2019-03-07habanalabs: keep track of the device's dma maskOded Gabbay
This patch refactors the code that is responsible to set the DMA mask for the device. Upon each change of the dma mask, the driver will save the new value that was set. This is needed in order to make sure we don't try to increase the mask a second time, in case we failed in the first time. This is especially relevant for Power machines, as that may cause a change in configuration of the TVT which will break the device. Goya will first try to set the device's dma mask to 39 bits, so that the memory that is allocated on the host machine for communication with the device's cpu will be in a bus address which is lower then 39 bits. Later, Goya will try to increase that mask to 48 bits, but only if setting the mask to 39 bits was successful. Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com>

2019-03-03habanalabs: prevent host crash during suspend/resumeOded Gabbay
This patch fixes the implementation of suspend/resume of the device so that upon resume of the device, the host won't crash due to PCI completion timeout. Upon suspend, the device is being reset due to PERST. Therefore, upon resume, the driver must initialize the PCI controller as if the driver was loaded. If the controller is not initialized and the device tries to access the device through the PCI bars, the host will crash with PCI completion timeout error.

2019-03-03habanalabs: perform accounting for active CSOded Gabbay
This patch adds accounting for active CS. Active means that the CS was submitted to the H/W queues and was not completed yet. This is necessary to support suspend operation. Because the device will be reset upon suspend, we can only suspend after all active CS have been completed. Hence, we need to perform accounting on their number.

2019-03-13habanalabs: complete user context cleanup before hard resetOmer Shpigelman
This patch fixes a bug which led to a crash during hard reset flow. Before a hard reset is executed, we wait a few seconds for the user context cleanup to complete. If it wasn't completed, we kill the user process and move on to the reset flow. Upon killing the user process, the context cleanup flow begins and may take a while due to MMU unmaps. Meanwhile, in the driver reset flow, we change the PCI DRAM bar location which can interfere with the MMU that uses the bar. If the context cleanup flow didn't finish quickly, a crash may occur due to PCI DRAM bar mislocation during the MMU unmap. Hence adding a wait between killing the user process and the start of the reset flow. Signed-off-by: Omer Shpigelman <oshpigelman@habana.ai> Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com>

When a DRAM page is mapped by the user, its default mapping is overwritten. Once that page is unmapped, the MMU driver will map that page to the default page. To help debugging, the driver will set the default page area to 0x99 on device initialization.

2019-02-27habanalabs: allow memory allocations larger than 4GBOded Gabbay
This patch increase the size field in the uapi structure of the Memory IOCTL from 32-bit to 64-bit. This is to allow the user to allocate and/or map memory in chunks that are larger then 4GB. Goya's device memory (DRAM) can be up to 16GB, and for certain topologies, the user may want an allocation that is larger than 4GB. This change doesn't break current user-space because there was a "pad" field in the uapi structure right after the size field. Changing the size field to be 64-bit and removing the pad field maintains compatibility with current user-space.
