chs fd34ea77eb remove checks for failure after memory allocation calls that cannot fail: kmem_alloc() with KM_SLEEP kmem_zalloc() with KM_SLEEP percpu_alloc() pserialize_create() psref_class_create() all of these paths include an assertion that the allocation has not failed, so callers should not assert that again.		2017-06-01 02:45:05 +00:00

This directory contains `rasops', a set of raster operations intended to
replace the dev/rcons/raster stuff for both wscons and rcons. It yields
significantly improved performance, supports multiple depths and color.

Issues/TODO:

- There is no generic `putchar' function for 2bpp
- Color handling for 2bpp is broken
- 64-bit types are not used on machines that are 64-bit
- We should never be doing reads/writes of less than 32-bits
- Flags in attribute values are hardcoded
- Need a manpage
- Should handle multiple fonts simulatneously
- Generate an `empty' box character when we have no match?
- Use 'int' in lieu of 'int32' where we can
- Compress some cases in rasops1.c
