[Bug 67215] New: UBO access seems to mask address on nouveau
...d correctly and everything else starts at zero.
My uniform buffer was 128k big and I copyed as I wanted to proove and I got a
correct rendering.
I think the mask is because of 16bit indices for uniform locations. This is
valid for uniform block offsets, but not for uniform buffer offsets.
eg:
u16 uniform_block_offset_per_variable; // hard coded in shader
u32 uniform_buffer_offset_per_uniform_block; // set by glBindBufferRange
u8* uniform_buffer_base; // location of this uniform buffer
// The way I think it's done:
u8* fetched_location = uniform_buffer_base +
u16(uniform_buffer_offset_per_uniform_block +
uniform_blo...
