There are too many register offset mismatch between mmhub v2.0 and v2.3. E.X: mmMM_ATC_L2_MISC_CG: 0x064a(v2.0) 0x06cd(v2.3) mmMMVM_L2_PROTECTION_FAULT_CNTL: 0x0688(v2.0) 0x0708(v2.3) mmMMVM_CONTEXT0_PAGE_TABLE_BASE_ADDR_LO32: 0x072b(v2.0) 0x0940(v2.3) mmMMVM_CONTEXT0_PAGE_TABLE_BASE_ADDR_HI32: 0x072c(v2.0) 0x0941(v2.3) mmMMVM_INVALIDATE_ENG0_REQ: 0x06e3(v2.0) 0x0a01(v2.3) mmMMVM_INVALIDATE_ENG0_ACK: 0x06f5(v2.0) 0x0a02(v2.3) mmMMVM_CONTEXT0_CNTL: 0x06c0(v2.0) 0x0740(v2.3) mmMMVM_L2_PROTECTION_FAULT_STATUS: 0x068c(v2.0) 0x070c(v2.3) mmMMVM_L2_PROTECTION_FAULT_CNTL: 0x0688(v2.0) 0x0708(v2.3) mmMM_ATC_L2_MISC_CG: 0x064a(v2.0) 0x06cd(v2.3) mmDAGB0_CNTL_MISC2: 0x0071(v2.0) 0x0096(v2.3) ... Continuing using the same file mmhub v2.0 is not good choice, it will introduce a lot of checking with ASIC types. And also easy to introduce the issues that offset not align, this kind of issues are really hard to find. Van Gogh's mmhub vm invalidation is actually caused by the offset mismatch as well. So it would like to create a new file rather than stick to re-use orignal mmhub v2.0 here. v2: add missed translate_further programming. v3: sync with latest code v4: add missing callbacks Signed-off-by: Huang Rui <ray.huang@amd.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
