* Linux 5.17+ support and allow including nvdebug.h independentlyJoshua Bakita2024-04-11
| | | | | - Move Linux-specific functions to nvdebug_linux.h and .c - Workaround PDE_DATA() being pde_data() on Linux 5.17+
* Expand support for printing LCE<->PCE and GRCE->LCE configurationrtas24-aeJoshua J Bakita2023-11-08
| | | | | | | | Tested working on Pascal, Volta, Volta Integrated, Turing, Ampere, and Ada. Also clean up minor spacing issues, an errantly added file (nvdebug.mod), and fix some inconsistencies with upstream.
* Created new read function in device_info for GRCE mappings and Pascal LCE ↵Saman Sahebi2023-10-29

* Improve copy engine register documentation in nvdebug.h + cleanupJoshua Bakita2023-07-20

* Fix addressing, zero-init, and compatibility bugs in a3fe378Joshua Bakita2023-07-03
| | | | | | | | | - Including missing dereference to finish getting the address of the control register range - Add zero-initialization to the proc_ops structure in copat_ops to insure that all intentionally unset fields remain unset - Set .llseek in all the file_operations structures, as recent kernels require this to be explictly set
* Hacky support for Linux 5.6+ and the Jetson AGX OrinJoshua Bakita2023-06-29
| | | | | | | | | | | | | | Works around change in parameters to proc initialization functions via a hacky function which rewrites the layout. This also required making all the struct file_operations writable. Also start reducing dependency on nvgpu headers. Known issues: - Incorrect message printed in log after module is loaded. Unclear if this is because the register detection logic is broken, or if the layout of the data at NV_MC_BOOT_0 has changed. - Not tested
* Quick dump of current state for Ben to review.Joshua Bakita2023-06-22
