Macro code stays shared by the channels of a process, but each channel
now has its own MME data RAM. Title 1's channels keep their own QMD ring
base in data word 0x27; with one shared RAM every channel used the last
channel's ring, QMDs collided, releases came early or never and the GPU
waited on semaphores (4 s timeouts per frame).
The QMD scheduler state is one table for all channels: a QMD's
dependency counter is state of the QMD, scheduled and decremented from
different channels.
Diagnostics: EDEN_NX2_QMD_TRACE (scheduler loads, counts, launches) and
EDEN_NX2_MME_DUMP (compute macro code, calls, data word 0x27 changes).

From changes.patch: the TU104/GA10x MME interpreter (shared macro context for
the process's channels, also on the compute class), native compute with QMD
3.0 dependency scheduling, the Ampere-to-Maxwell shader lowering, native
vertex stream sizes, and the console's GOB swizzle for textures, DMA copies
and the host unswizzle shaders. Switch 2 channels turn all of it on at init.
The lowering is widened for title 4 (all 32 of its programs lower): general
TEX (any dimension/LOD/mask, operand split 1+1/2+1/2+2/4+n, any but consistent
descriptor buffer), cube/array, SULD channel masks, 128-bit STG, indexed IPA,
VOTE, SHFL with any immediate or predicate output, R2P/P2R byte select,
uniform ULOP3/ULEA/UBREV/UFLO.SH/UISETP signed/UMOV URZ, IMNMX cbuf, IADD3
and FFMA uniform operands, FMUL /4 /8 x8, and BSSY/BSYNC/BREAK/WARPSYNC as
no-ops. The capture stops at unmapped memory. EDEN_NX2_SHADER_DUMP dumps every
native program; tools in C:\dev\nx2work test the lowering offline.

NVN2 gates command buffers with semaphores the CPU releases after writing
them. Eden read past unmet SEMAPHORED acquires, so it executed stale commands
and desynchronised. Channels now suspend on an unmet acquire and resume from
the same word once it is met (scheduler keeps the waiting channels, the GPU
thread polls them), as in changes.patch.
Also: methods split across GPFIFO entries around a called command buffer are
set aside and resumed; subchannel 2 defaults to inline-to-memory; unbound
subchannels and out-of-range compute/DMA methods are dropped instead of
crashing; 4-byte semaphore releases no longer write 16 bytes; Ampere
SEM_PAYLOAD_HI/SEM_EXECUTE no longer spin as Kepler acquires; unmapped GPU
reads log instead of asserting. Debug aids: EDEN_NX2_PB_CHECK (pushbuffer
changed after submit), EDEN_NX2_QUERY_TRACE, a one-time pushbuffer dump.

(#4086)
Contains the minimal set of functionalities to allow tico installer succeed, and tico work normally EXCEPT for game launching (which me or someone else will investigate later)
First three commits are from PR 4012.
The other six, kinda dizzy to explain each one. All were implemented based on tico source, switchbrew and libnx.
Hopefully the commit messages will do.

reworked a bit to remove references of parent objects and instead pass as arguments to methods to prevent useless reloads
