This should be done once as you fetch the context, and then cached - * as part of the context data structure, so it's cheap to access. - * -# If there's a clear and arguable inefficiency in using Dynamic Properties, - * then use a Compile-Time Property (Platform Config, or Midgard Compile-time - * property). Examples of where this might be sensible follow: - * - Part of a critical inner-loop - * - Frequent re-use throughout the driver, causing significant extra load - * instructions or control flow that would be worthwhile optimizing out. - * - * We cannot provide an exhaustive set of examples, neither can we provide a - * rule for every possible situation. Use common sense, and think about: what - * the rest of the driver will be doing; how the compiler might represent the - * value if it is a compile-time constant; whether an OEM shipping multiple - * devices would benefit much more from a single DDK binary, instead of - * insignificant micro-optimizations. - * - * @section sec_base_user_api_gpuprops_dyn Dynamic GPU Properties - * - * Dynamic GPU properties are presented in two sets: - * -# the commonly used properties in @ref base_gpu_props, which have been - * unpacked from GPU register bitfields. - * -# The full set of raw, unprocessed properties in @ref gpu_raw_gpu_props - * (also a member of @ref base_gpu_props). All of these are presented in - * the packed form, as presented by the GPU registers themselves. - * - * @usecase The raw properties in @ref gpu_raw_gpu_props are necessary to - * allow a user of the Mali Tools (e.g. PAT) to determine "Why is this device - * behaving differently?". In this case, all information about the - * configuration is potentially useful, but it <b>does not need to be processed - * by the driver</b>. Instead, the raw registers can be processed by the Mali - * Tools software on the host PC. - * - * The properties returned extend the Midgard Configuration Discovery - * registers. For example, GPU clock speed is not specified in the Midgard - * Architecture, but is <b>necessary for OpenCL's clGetDeviceInfo() function</b>. - * - * The GPU properties are obtained by a call to - * _mali_base_get_gpu_props(). This simply returns a pointer to a const - * base_gpu_props structure. It is constant for the life of a base - * context. Multiple calls to _mali_base_get_gpu_props() to a base context - * return the same pointer to a constant structure. This avoids cache pollution - * of the common data. - * - * This pointer must not be freed, because it does not point to the start of a - * region allocated by the memory allocator; instead, just close the @ref - * base_context. - * - * - * @section sec_base_user_api_gpuprops_config Platform Config Compile-time Properties - * - * The Platform Config File sets up gpu properties that are specific to a - * certain platform. Properties that are 'Implementation Defined' in the - * Midgard Architecture spec are placed here. - * - * @note Reference configurations are provided for Midgard Implementations, such as - * the Mali-T600 family. The customer need not repeat this information, and can select one of - * these reference configurations. For example, VA_BITS, PA_BITS and the - * maximum number of samples per pixel might vary between Midgard Implementations, but - * \b not for platforms using the Mali-T604. This information is placed in - * the reference configuration files. - * - * The System Integrator creates the following structure: - * - platform_XYZ - * - platform_XYZ/plat - * - platform_XYZ/plat/plat_config.h - * - * They then edit plat_config.h, using the example plat_config.h files as a - * guide. - * - * At the very least, the customer must set @ref CONFIG_GPU_CORE_TYPE, and will - * receive a helpful \#error message if they do not do this correctly. This - * selects the Reference Configuration for the Midgard Implementation. The rationale - * behind this decision (against asking the customer to write \#include - * <gpus/mali_t600.h> in their plat_config.h) is as follows: - * - This mechanism 'looks' like a regular config file (such as Linux's - * .config) - * - It is difficult to get wrong in a way that will produce strange build - * errors: - * - They need not know where the mali_t600.h, other_midg_gpu.h etc. files are stored - and - * so they won't accidentally pick another file with 'mali_t600' in its name - * - When the build doesn't work, the System Integrator may think the DDK is - * doesn't work, and attempt to fix it themselves: - * - For the @ref CONFIG_GPU_CORE_TYPE mechanism, the only way to get past the - * error is to set @ref CONFIG_GPU_CORE_TYPE, and this is what the \#error tells - * you. - * - For a \#include mechanism, checks must still be made elsewhere, which the - * System Integrator may try working around by setting \#defines (such as - * VA_BITS) themselves in their plat_config.h. In the worst case, they may - * set the prevention-mechanism \#define of - * "A_CORRECT_MIDGARD_CORE_WAS_CHOSEN". - * - In this case, they would believe they are on the right track, because - * the build progresses with their fix, but with errors elsewhere. - * - * However, there is nothing to prevent the customer using \#include to organize - * their own configurations files hierarchically. - * - * The mechanism for the header file processing is as follows: - * - * @dot - digraph plat_config_mechanism { - rankdir=BT - size="6,6" - - "mali_base.h"; - "gpu/mali_gpu.h"; - - node [ shape=box ]; - { - rank = same; ordering = out; - - "gpu/mali_gpu_props.h"; - "base/midg_gpus/mali_t600.h"; - "base/midg_gpus/other_midg_gpu.h"; - } - { rank = same; "plat/plat_config.h"; } - { - rank = same; - "gpu/mali_gpu.h" [ shape=box ]; - gpu_chooser [ label="" style="invisible" width=0 height=0 fixedsize=true ]; - select_gpu [ label="Mali-T600 | Other\n(select_gpu.h)" shape=polygon,sides=4,distortion=0.25 width=3.3 height=0.99 fixedsize=true ] ; - } - node [ shape=box ]; - { rank = same; "plat/plat_config.h"; } - { rank = same; "mali_base.h"; } - - "mali_base.h" -> "gpu/mali_gpu.h" -> "gpu/mali_gpu_props.h"; - "mali_base.h" -> "plat/plat_config.h" ; - "mali_base.h" -> select_gpu ; - - "plat/plat_config.h" -> gpu_chooser [style="dotted,bold" dir=none weight=4] ; - gpu_chooser -> select_gpu [style="dotted,bold"] ; - - select_gpu -> "base/midg_gpus/mali_t600.h" ; - select_gpu -> "base/midg_gpus/other_midg_gpu.h" ; - } - @enddot - * - * - * @section sec_base_user_api_gpuprops_kernel Kernel Operation - * - * During Base Context Create time, user-side makes a single kernel call: - * - A call to fill user memory with GPU information structures - * - * The kernel-side will fill the provided the entire processed @ref base_gpu_props - * structure, because this information is required in both - * user and kernel side; it does not make sense to decode it twice. - * - * Coherency groups must be derived from the bitmasks, but this can be done - * kernel side, and just once at kernel startup: Coherency groups must already - * be known kernel-side, to support chains that specify a 'Only Coherent Group' - * SW requirement, or 'Only Coherent Group with Tiler' SW requirement. - * - * @section sec_base_user_api_gpuprops_cocalc Coherency Group calculation - * Creation of the coherent group data is done at device-driver startup, and so - * is one-time.
