Drew Galbraith 10d16e129f [Zion] Use a slab allocator for 64 byte and 128 byte allocs. 
This has no effect on page usage for now (each uses a small amount of
pages so has some overhead.

However it does reduce the active allocations from
234 -> 146 (64B)
61 -> 51 (128B)

Drew Galbraith cc16210e90 [Zion] Use slab allocators immediately during heap init. 2023-11-15 13:02:34 -08:00
Drew Galbraith 659f122c9e [Zion] Free memory that was allocated with the slab allocator. 
This reduces the number of active allocs by ~ 200.
Size 8: 142 -> 2
Size 16: 319 > 313
Size 32: 364-> 312

Drew Galbraith 6d27ee5dc5 [Zion] Add more debug information about kernel heap usage. 
This will be helpful as we work to improve it.

Without deallocations, we currently stand at the following alloc numbers
8 - 142
16 - 319
32 - 364

unsized - 305

total page usage including slabs is 12.

Drew Galbraith 792e5155ba [Glacier] When resizing vector use the proper T constructor. 
Previously when we static_casted from uint8_t[] to T[] we ended
up not properly initializing the objects in the array. This caused
issues where garbage memory provided by new was treated as a legitimate
object.

Potentially in the future it would make sense to back vectors with
a simple byte array and do memcpys to move objects in and out as
needed.

Drew Galbraith e5568450c2 [Zion] Make kernel slab allocation failures less chatty. 
We started to hit this constraint but the allocators are due for
a redesign that actually does deallocation soon.
