* -push constants

* -descriptor set entries

|
|

* push constants should be one read
|
|
*
|
|
* buffers and images are handled through the TMU pipeline
|
|
* and therefore carry implicit uniform reads
|
|
* buffers should be one uniform (general memory read)
|
|
* number of uniforms for images are dependent on type (and TMU writes)
|
|
*
|
|
* therefore what we need is a mapping for each assembly uniform read
|
|
* to some vulkan resource
|
|
* and the driver should be able to figure out what to put in the uniform queue
|
|
* based on the mapping
|
|
*
|
|
* vertex and coordinate shader mappings are shared
