MIP Operating System xv6 ASM 源码-MIP Operating System xv6 ASM source code

handle base_level when not using a mip filter, min max level is unfortunately ignored by the hardware otherwise.this is a tad stupid of the hardware, but there s no non-rcomp z16 z24 texture formats to be had, we have to suffer and lose some precisio

To avoid as-yet-unnecessary complexity we don t allow any partial support of MIP Maps (e.g. only for POT textures).

Can t control max lod. For first level views and when we only look at one level we disable mip filtering to achive the same results as a view.
