Synopsis

Documentation

getShaderInfoAMD Source #

Arguments

:: forall io. MonadIO io 
=> Device

device is the device that created pipeline.

-> Pipeline

pipeline is the target of the query.

-> ShaderStageFlagBits

shaderStage identifies the particular shader within the pipeline about which information is being queried.

-> ShaderInfoTypeAMD

infoType describes what kind of information is being queried.

-> io (Result, "info" ::: ByteString) 

vkGetShaderInfoAMD - Get information about a shader in a pipeline

Description

If pInfo is NULL, then the maximum size of the information that can be retrieved about the shader, in bytes, is returned in pInfoSize. Otherwise, pInfoSize must point to a variable set by the user to the size of the buffer, in bytes, pointed to by pInfo, and on return the variable is overwritten with the amount of data actually written to pInfo.

If pInfoSize is less than the maximum size that can be retrieved by the pipeline cache, then at most pInfoSize bytes will be written to pInfo, and getShaderInfoAMD will return INCOMPLETE.

Not all information is available for every shader and implementations may not support all kinds of information for any shader. When a certain type of information is unavailable, the function returns ERROR_FEATURE_NOT_PRESENT.

If information is successfully and fully queried, the function will return SUCCESS.

For infoType SHADER_INFO_TYPE_STATISTICS_AMD, a ShaderStatisticsInfoAMD structure will be written to the buffer pointed to by pInfo. This structure will be populated with statistics regarding the physical device resources used by that shader along with other miscellaneous information and is described in further detail below.

For infoType SHADER_INFO_TYPE_DISASSEMBLY_AMD, pInfo is a pointer to a UTF-8 null-terminated string containing human-readable disassembly. The exact formatting and contents of the disassembly string are vendor-specific.

The formatting and contents of all other types of information, including infoType SHADER_INFO_TYPE_BINARY_AMD, are left to the vendor and are not further specified by this extension.

Valid Usage (Implicit)

  • device must be a valid Device handle
  • pipeline must be a valid Pipeline handle
  • shaderStage must be a valid ShaderStageFlagBits value
  • infoType must be a valid ShaderInfoTypeAMD value
  • pInfoSize must be a valid pointer to a size_t value
  • If the value referenced by pInfoSize is not 0, and pInfo is not NULL, pInfo must be a valid pointer to an array of pInfoSize bytes
  • pipeline must have been created, allocated, or retrieved from device

VkShaderStatisticsInfoAMD - Statistical information about a particular shader within a pipeline

Description

Some implementations may merge multiple logical shader stages together in a single shader. In such cases, shaderStageMask will contain a bitmask of all of the stages that are active within that shader. Consequently, if specifying those stages as input to getShaderInfoAMD, the same output information may be returned for all such shader stage queries.

The number of available VGPRs and SGPRs (numAvailableVgprs and numAvailableSgprs respectively) are the shader-addressable subset of physical registers that is given as a limit to the compiler for register assignment. These values may further be limited by implementations due to performance optimizations where register pressure is a bottleneck.
