Drew Galbraith 84d3caaba5 [Teton] Get framebuffer info from yellowstone. 2023-11-15 16:42:00 -08:00
Drew Galbraith 0ced0032ff Move qemu startup to its own script.
This causes us to reinstall and rebuild the image each time
we run qemu. This necessary now that we are loading files
from the disk because cmake makes it tricky (impossible?) to
have a command rely on a different target being "installed".

Because of this, updates to the teton executable were not being
picked up on the image.

Drew Galbraith 92d8a02291 [Zion] Cleanup memory debug statistics slightly. 2023-11-15 13:10:53 -08:00
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
2023-11-15 12:53:14 -08:00
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 d71d543b2a [Zion] Move to a kernel slab allocator that will allow easier dealloc. 2023-11-15 12:04:35 -08:00
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.
