From: Xiaojie Yuan Date: Thu, 20 Jun 2019 15:18:50 +0000 (-0500) Subject: drm/amdgpu/discovery: add ip discovery initial support X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=f39f5bb1c9d68d557ff1539fea7adfe7c4d4ed7a;p=openwrt%2Fstaging%2Fblogic.git drm/amdgpu/discovery: add ip discovery initial support The IP discovery table lists is populated by the psp at power on and includes all of the hw details on the board: - List of IPs and MMIO offsets - IP harvest details - IP configuration details v2: prefix struct and function names with 'amdgpu' v3: read table binary from vram using mmMM_INDEX and mmMM_DATA update TABLE_BINARY_MAX_SIZE to 64kb (1 TMR) add 'instance_number' field per ip info consider endianness and replace uint8/16/32_t with u8/16/32 initialize register base addresses initialize adev->gfx.config and adev->gfx.cu_info to replace gpu info fw get major and minor version using a single api don't expose internal data structures in amdgpu_discovery.h v4: RCC_CONFIG_MEMSIZE is in MB units hold mmio_idx_lock while reading ip discovery binary v5: pick out discovery.h as a cross-OS header do structure pointer cast directly consider endianness while using the member of structure convert base addresses to dword at boot up, PSP BL copies ip discovery binary from VBIOS(SPIROM) image to the top of the frame buffer (just below the reserved regions for PSP & SMU). ip discovery data table includes the collection of each ip's identification number, base addresses, version number, and harvest setting placeholder. gc data table includes gfx info structure.
