<p>
This document attempts to describe the Apple G13 GPU architecture, as used
in the M1 SoC. This is based on reverse engineering and is likely to have mistakes.
The Metal Shading Language is typically used to program these GPUs,
and this document uses Metal terminology. For example a CPU <em>SIMD-lane</em>
is a Metal <em>thread</em>, and a CPU <em>thread</em> is a Metal <em>SIMD-group</em>.
</p>

<p>
The G13 architecture has 32 threads per SIMD-group. Each SIMD-group has a
stack pointer (<code>sp</code>), a program counter (<code>pc</code>), a 32-bit
execution mask (<code>exec_mask</code>), and up to 128 general purpose registers.
</p>

<p>
General purpose registers each store one 32-bit value per thread. Each register
can be accessed as a 32-bit register, named <code>r0</code> to <code>r127</code>,
the low 16-bits of the register <code>r0l</code> to <code>r127l</code>, or
the high 16-bits of the register <code>r0h</code> to <code>r127h</code>.
Some instructions may also use pairs of contiguous 32-bit registers to operate
on 64-bit values, and memory operations may use up to four contiguous 16 or
32-bit registers (in both cases, encoded as the first register).
</p>

<p>
A number of physical registers are allocated to each SIMD-group, and registers
from <code>r0</code> to <code>r(N-1)</code> may be used, but accesses to higher
register numbers are not valid, and may read or corrupt data from other
SIMD-groups. Using fewer registers (e.g. by using 16-bit types instead of
32-bit types) allows more SIMD-groups to fit in the physical register file
(higher occupancy), which improves performance.
</p>

<p>
Certain instructions are hardcoded to use early registers. <code>r0l</code>
tracks the execution mask stack, and <code>r1</code> is used as the link register.
</p>

<p>
Shared state is less well understood, but includes 256 32-bit uniform registers
named <code>u0</code> to <code>u255</code> and similarly accessible as their
16-bit halves, <code>u0l</code> to <code>u255h</code>. These are used for values
that are the same across all threads, such as <code>threads_per_grid</code>, or
addresses of buffers.
</p>

<h2>Conditional Execution</h2>

<p>
Each thread within a SIMD-group may be deactivated, meaning the values in registers
for that thread will keep their current value. Whether or not each thread is active
is tracked in a 32-bit execution mask (in this document, by convention, a one bit
indicates the thread is active and a zero bit indicates it is not).
</p>

<p>
<code>r0l</code> tracks the execution mask stack. When used with flow-control
instructions, the value in <code>r0l</code> indicates how many 'pop' operations
will be needed to re-enable an inactive thread, or zero if the thread is active.
</p>

<p>
The execution mask stack instructions (<code>pop_exec</code>, <code>if_*cmp</code>,
<code>else_*cmp</code> and <code>while_*cmp</code>) are typically used to manage
<code>r0l</code>. They also update <code>exec_mask</code> based on the value in
<code>r0l</code>, and are the only known way to manipulate <code>exec_mask</code>.
However, <code>r0l</code> may be manipulated with other instructions. It should
be initialised to zero prior to using execution mask stack instructions, and
<code>break</code> statements may be implemented by conditionally moving
a value (corresponding to the number of stack-levels to break out of) to
<code>r0l</code> and using a <code>pop_exec 0</code> (which deactivates any
threads that now have non-zero values in <code>r0l</code>).
</p>

<p>
The <code>jmp_exec_none</code> instruction may be used to jump over an <code>if</code>
statement body if no threads are active, and the <code>jmp_exec_any</code> may be used
to jump back to the start of the loop only if one or more threads are still executing
the loop.
</p>

<p>
Execution masking generally prevents reading or writing values from inactive threads,
however SIMD shuffle instructions can read from inactive threads in some cases, which
can be valuable for research or debugging purposes (e.g. it allows observing non-zero
values in <code>r0l</code>).
</p>

<h2>Register Cache</h2>

<p>The GPU has a register cache, which keeps the contents of recently used general
purpose registers more quickly accessible. When instructions read or write GPRs,
they usually allow hints for the access to be encoded. The <code>cache</code> hint,
on a source or destination operand, indicates the value will be used again,
and should be cached (meaning other values, where this hint was not used, will
be preferred for eviction). The <code>discard</code> hint (on a source operand)
invalidates the value in the register cache after all operands have been read,
without writing it back to the register file.</p>

<p>While the <code>cache</code> hint should only change performance, the
<code>discard</code> hint will make future reads undefined, which could
lead to confusing issues. <code>discard</code> should probably not
be used within conditional execution, as inactive threads within the SIMD-group
may contain data that has not been written back to the register file that would
probably also also get discarded. The behaviour of this hint when execution is
partially or completely masked has not been tested.</p>

<p>
Either hint may be used multiple times even if the same operand appears twice,
and <code>discard</code> on a source register can be used with <code>cache</code>
on the same destination register.
</p>


<h1>Instructions</h1>

<p>
Instructions vary in length in multiples of two bytes up to twelve bytes (so far).
Some instructions have a long and short encoding. This is indicated by a bit
<code>L</code>, which, if zero, indicates the last two (or four) bytes of the
instruction are omitted, and any bits within those bytes should be read as zero.
So far only 12-byte instructions omit the last four bytes, and all others omit
the last two.
</p>

<p>
The encodings are described in little-endian, meaning bytes go right-to-left
(and top-to-bottom), but bits may be read in the usual numerical order.
</p>

<p>
Behaviour is mostly described in a Python-like pseudocode for now. In operand
descriptions, the <code>:</code> operator describes bit concatenation, with
the most-significant fields first. Elsewhere, values are considered to be
Python-style arbitrary-precision integers, and floating-point values are
considered to be arbitrary-precision floats (although double-precision with
round-to-odd may be an adequate approximation).

<h3>sin_pt_1</h3>

	<p>
	<code>sin_pt_1</code> is used together with <code>sin_pt_2</code> and
	supporting ALU to compute the sine function. sin_pt_1 takes an angle
	around the circle in the interval [0, 4) and produces an intermediate
	result. This intermediate result is then passed to sin_pt_2, and the
	two results are multipled to give sin. The argument reduction to [0, 4)
	can be computed with a few ALU instructions: <code>reduce(x) = 4
	fract(x / tau)</code>, where <code>tau</code> is the circle constant
	formerly known as twice pi. Calculating cosine follows from the
	identity <code>cos(x) = sin(x + tau/4)</code>. After multipling by
	<code>1/tau</code>, the bias become 1/4 which can be added in the same
	cycle via a fused multiply-add. Tangent should be lowered to a division
	of sine and cosine.

<h3>uniform_store</h3>

	<code>uniform_store</code> is used to initialise uniform registers.
	<code>R</code> is stored to offset <code>O</code>, which is typically an
	index in 16-bit units into the uniform registers. This is encoded like
	(and possibly is) a store to device memory, and can move one 16-bit register
	to initialise a 16-bit uniform, or two consecutive 16-bit registers to
	initialise a 32-bit uniform.

<h3>device_load</h3>

	<p>
	<code>device_load</code> initiates a load from device memory, the result
	of which may be used after a <code>wait</code>.

	The data can be unpacked from a variety of formats, or passed through as-is.

	On each thread, up to four aligned values, each up to 32-bits, can be
	read from a base address plus an offset (shifted left by the alignment,
	with an optional additional left shift of up to two).
	</p>

	<p>
	The number of values to read is described by a mask,
	such that <code>0b0001</code> indicates one value, or <code>0b1111</code>
	loads four values. Non-contiguous masks skip values in memory,
	but still write the result to contiguous registers.
	</p>

	<p>
	Non-packed formats (8, 16, and 32-bit values) are zero
	extended. All packed values are unpacked to 16-bit or 32-bit floating-point
	values, depending on the size of the register. Bit-packed formats (<code>rgb10a2</code>,
	<code>rg11b10f</code> and <code>rgb9e5</code>)</code> are supported, but ignore the optional
	shift and the mask. They always read an aligned 32-bit value, and write to the same number of
	registers. However simple packed values (<code>unorm8</code>, <code>snorm8</code>,
	<code>unorm16</code>, <code>snorm16</code> and <code>srgba8</code>) do not have this limitation.
	</p>

	<p>
	Unaligned addresses are rounded-down to the required alignment. The base address (<code>A</code>)
	is a 64-bit value from either uniform or general-purpose registers. The offset (<code>O</code>) may
	be a signed 16-bit immediate, or a signed or unsigned 32-bit general-purpose register.
	</p>
