habanalabs: move driver to accel subsystem

2023-01-26T09:52:10+00:00

Now that we have a subsystem for compute accelerators, move the habanalabs driver to it. This patch only moves the files and fixes the Makefiles. Future patches will change the existing code to register to the accel subsystem and expose the accel device char files instead of the habanalabs device char files. Update the MAINTAINERS file to reflect this change. Signed-off-by: Oded Gabbay

habanalabs: build ASICs from new to old

2022-09-20T12:42:08+00:00

Newer ASICs code changes more often, has more chance to fail compilation. So, let's compile them first so errors in those files will fail compilation sooner. Signed-off-by: Ohad Sharabi Reviewed-by: Oded Gabbay Signed-off-by: Oded Gabbay

habanalabs: add gaudi2 asic-specific code

2022-07-12T06:09:27+00:00

Add the ASIC-specific code for Gaudi2. Supply (almost) all of the function callbacks that the driver's common code need to initialize, finalize and submit workloads to the Gaudi2 ASIC. It also contains the code to initialize the F/W of the Gaudi2 ASIC and to receive events from the F/W. It contains new debugfs entry to dump razwi events. razwi is a case where the device's engines create a transaction that reaches an invalid destination. Signed-off-by: Oded Gabbay

habanalabs: create common folder

2020-07-24T17:31:37+00:00

For internal needs of our CI we need to move all the common code into a common folder instead of putting them in the root folder of the driver. Same applies to the common header files under include/ Signed-off-by: Oded Gabbay Reviewed-by: Omer Shpigelman

habanalabs: add gaudi asic-dependent code

2020-05-19T11:48:41+00:00

Add the ASIC-dependent code for GAUDI. Supply (almost) all of the function callbacks that the driver's common code need to initialize, finalize and submit workloads to the GAUDI ASIC. It also contains the code to initialize the F/W of the GAUDI ASIC and to receive events from the F/W. Signed-off-by: Oded Gabbay

treewide: Add SPDX license identifier - Makefile/Kconfig

2019-05-21T08:50:46+00:00

habanalabs: Move PCI code into common file

2019-03-05T14:48:42+00:00

Move duplicated PCI-related code from ASIC-specific files into the common pci.c file. Signed-off-by: Tomer Tayar Signed-off-by: Oded Gabbay

habanalabs: Move device CPU code into common file

2019-03-04T08:22:09+00:00

This patch moves the code that is responsible of the communication vs. the F/W to a dedicated file. This will allow us to share the code between different ASICs. Signed-off-by: Tomer Tayar Signed-off-by: Oded Gabbay

habanalabs: add debugfs support

2019-02-18T08:46:46+00:00

This patch adds debugfs support to the driver. It allows the user-space to display information that is contained in the internal structures of the driver, such as: - active command submissions - active user virtual memory mappings - number of allocated command buffers It also enables the user to perform reads and writes through Goya's PCI bars.

habanalabs: add virtual memory and MMU modules

2019-02-18T08:46:46+00:00

This patch adds the Virtual Memory and MMU modules. Goya has an internal MMU which provides process isolation on the internal DDR. The internal MMU also performs translations for transactions that go from Goya to the Host. The driver is responsible for allocating and freeing memory on the DDR upon user request. It also provides an interface to map and unmap DDR and Host memory to the device address space. The MMU in Goya supports 3-level and 4-level page tables. With 3-level, the size of each page is 2MB, while with 4-level the size of each page is 4KB. In the DDR, the physical pages are always 2MB.
