+Subject: avcodec/arm/sbcenc: avoid callee preserved vfp registers
+
+When compiling FFmpeg with GCC-9, some very random segfaults were
+observed in code which had previously called down into the SBC encoder
+NEON assembly routines. This was caused by these functions clobbering
+some of the vfp callee saved registers (d8 - d15 aka q4 - q7). GCC was
+using these registers to save local variables, but after these
+functions returned, they would contain garbage.
+
+Fix by reallocating the registers in the two affected functions in
+the following way:
+ ff_sbc_analyze_4_neon: q2-q5 => q8-q11, then q1-q4 => q8-q11
+ ff_sbc_analyze_8_neon: q2-q9 => q8-q15
+
+The reason for using these replacements is to keep closely related
+sets of registers consecutively numbered which hopefully makes the
+code more easy to follow. Since this commit only reallocates
+registers, it should have no performance impact.
+
+Upstream-status: Pending

++@ General notes:
++@
++@ Residual is generally only guaranteed to be clipped to 16 bits.
++@ This means that we do need to do vmovl, vqadd, vqmovun
++@ rather than vaddw, vqmovun (if we were clipped to 15 then we could get away
++@ with this).
++@
++@ There is an exception for the DC case because its transform is guaranteed
++@ to be small enough that overflow cannot occur during the first add.

++@ Horizontal Patch functions

++@ Assumptions:
++@ (that wouldn't apply to all frame layoouts but do apply to sand, so beware
++@  if reuseing this code)
++@
++@ Min ctb size is 8 so we don't need to worry about tr_size or dl_size for
++@ N==4, but do for chroma N>=8.  As we share Y/C fns that means we can ignore
++@ N==8,PW=8 (chroma always PW>8) but have to cope for larger
++@
++@ We always have at least 64 pixel H frame width rounding - this lets us
++@ load UR widthout having to worry about exactly how many pixels are actually
++@ within the frame.  As partial loads will only occur very occasionally this
++@ should be a win in nearly all cases.
++@
++@ 16 bit fns can be used as 8 bit chroma fns as chroma never filters
++@ so we do no maths on the contents
++@
++@ No filtering in 32bit fns as they are chroma only

++# Logic here should be good to 14 bits without modification
++# but only 8 & 10 are currently instantiated & tested
++# 15 & 16 bits have different shift1, shift2 calc & I also suspect overflow
++# in _p00 & _b00
++
++# The @ "mul_used", 0 annotations that occur by various mul blocks suppress
++# the warning that we are using rotation & ra/rb registers. r0..3 can be
++# rotated through all 16 elems ra regs can only be rotated through their
++# local 4.  As it happens this is what is wanted here as we do not want the
++# constants from the other half of the calc.
++
++# Number limits in P/B calculation
++#
++# In order to avoid issues with mul24 being an unsigned 24->32 bit multiplier
++# we offset our intermediates s.t. they always end up +ve before the next
++# multiply (may be -ve whilst summing but that doesn't matter).
++#
++# Range calc for up to 14 bits (Y-B pred):
++#
++# denom: [0, 7]
++# bmax = (1 << bits) - 1
++# off: [-(1 << (bits-1)), (1 << (bits-1)) - 1]
++#
++# wt_mul: [-128, 255]
++# wt_off = off * 2 + 1: [-bmax, bmax]
++#

++# V-filter: [(-22*hf + 88*hf) >> 6] = [0x580, 0xc28e]
++# mul_t = (V_L0 + V_l1) * (wt_mul + 128): [0, 0x24624e6]
++# mul_t - (V_l0 + V_l1)* 128: [-0xc28e00, 0x18396e4]

++#  [wt_off << (21 - bits)] - [wt_mul << 15] = [-0x1fffff, 0x1fffff] - [-0x400000, 0x7f8000]
++#
++# This all looks good and is mostly bit depth independant - and as we manage
++# to do unsigned multiplies everywhere (now) this should be good for any bit
++# depth up to 14 (we could probably do 16 - but that requires a few tweaks
++# to the shifts we don't currently have logic for)
++
++# PREREAD is the number of requests that we have sitting in the TMU request
++# queue.
++#
++# There are 8 slots availible in the TMU request Q for tm0s requests, but
++# only 4 output FIFO entries and overflow is bad (corruption or crash)
++# (If threaded then only 2 out FIFO entries, but we aren't.)
++# In s/w we are effectively limited to the min vertical read which is >= 4
++# so output FIFO is the limit.
++#
++# As the test for read-next is is the main part of the Luma loop (rather than
++# the preload FIFO part) we are limited to min_luma_height - 1
++# Min_luma_height is 4 so we can only have a preload of 3
++# Beware that min_chroma_height (and_width) is 2 so we can't do the same trick
++# in chroma without abandoning preload pretty much entirely (which would be bad)

++# HEVC VPU Transform
++#
++# Transform matrix can be thought of as
++#   output row vector = input row vector * transMatrix2
++#
++# The even rows of the matrix are symmetric
++# The odd rows of the matrix are antisymmetric
++#
++# So only need to compute the first half of the results, then can compute the remainder with a butterfly
++#
++# EXAMPLE
++#   (a b c d) (1 2  2  1)
++#             (3 4 -4 -3)
++#             (5 6  6  5)
++#             (7 8 -8 -7)
++#
++#  x=(a c)(1 2) = 1a+5c 2a+6c
++#         (5 6)
++#
++#  y=(b d)(3 4) = 3b+7d 4b+8d
++#         (7 8)
++#
++#  u=x+y = 1a+5c+3b+7d 2a+4b+6c+8d
++#  v=x-y = 1a+5c-3b-7d 2a+6c-4b-8d
++#
++#  Final results are (u , v[::-1])
++#
++#
++#  For 32x1 input, load even rows into HX(0++,0), odd rows into HX(16++,0)
++#  Apply the even matrix first and stop before rounding
++#  Then apply the odd matrix in a full manner:
++#
++#   First step is to compute partial products with the first input (16 cycles)
++#   1a 3b 5c 7d   16x1 input coefficients produce 16x16 output
++#   2a 4b 6c 8d
++#   2a -4b 6c -8d
++#   1a -3b 5c -7d
++#
++#   Second step is to sum partial products into final position (8 cycles)
++#   1a+3b+5c+7d
++#   2a+4b+6c+8d
++#   2a-4b+6c-8d
++#   1a-3b+5c-7d
++#
++#   Then can apply butterfly to combine even results and odd results + rounding to produce 16 rows of output at a time (need to save in transposed format)
++#
++#   For 16x16 no butterfly is required and can store final results in original location  (Could do 2 16x16s in parallel to make use of the trick - saves on the adds)
++#
++#   For 8x8 we could compute two in parallel.
++#
++#
++
++# Columns are transformed first
++#
++# Store top left half of transMatrix2 in
++# Store bottom left half of transMatrix2 in HX(32,32)
++#
++# For 16x16
++# HX(0:15,0) contains input data before transform
++# HY(0:15,0) contains 32bit output data after transform
++# HX(32,0) contains even rows of left half of transMatrix2
++# HX(32,32) contains odd rows of left half of transMatrix2
++# HY(48,0) contains partial products ready for summing

++@ General notes:
++@ Having done some timing on this in sand8->y8 (Pi4)
++@  vst1 (680fps) is a bit faster than vstm (660fps)
++@  vldm (680fps) is noticably faster than vld1 (480fps)
++@  (or it might be that a mix is what is required)
++@
++@ At least on a Pi4 it is no more expensive to have a single auto-inc register
++@ for dest address than it is to have 2 used alternately (On Pi3 Ben asserted
++@ the latter was better)
++@
++@ vstm will bus error on unaligned access (so will vldm), vst1 is safe unless
++@ the memory is uncached.
++@ As these are Sand -> planar we can assume that src is going to be aligned but
++@ it is possible that dest isn't (converting to .yuv or other packed format).
++@ Luckily vst1 is faster than vstm :-) so all is well
++@ vst1 has alignment requirements of el size so maybe splitting vst1.32 into 4
++@ .8 stores would let us do non-word aligned stores into uncached but it
++@ probably isn't worth it.

++Building Pi FFmpeg
++==================
++
++Configuration:
++=============
++
++These instructions work for cross compiles from Ubuntu 16.04 & Ubuntu
++18.04. I would expect most other linux environments to work but I haven't
++tried them.
++
++pi-util/conf_pi2.sh
++
++contains suitable options to build the code for Pi2/3.  It expects to find
++git clones of
++
++https://github.com/raspberrypi/tools
++https://github.com/raspberrypi/firmware
++
++in the parent of the FFmpeg directory.  I recommend using --depth 1 to avoid a
++lot of history you don't want.
++
++If you have a copy of qasm.py in ../local/bin then the .qasm sources will be
++rebuilt.  Otherwise the prebuilt .c & .h files will be used.
++Likewise ../local/bin/vasmvidcore_std will enable VPU code rebuild
++
++pi-util/conf_p1.sh should configure for Pi1.  Beware that as of this time
++H265 QPU acceleration is broken on Pi1 and so it is disabled.

++Notes on the hevc_rpi decoder & associated support code
++-------------------------------------------------------
++
++There are 3 main parts to the existing code:
++
++1) The decoder - this is all in libavcodec as rpi_hevc*.
++
++2) A few filters to deal with Sand frames and a small patch to
++automatically select the sand->i420 converter when required.
++
++3) A kludge in ffmpeg.c to display the decoded video. This could & should
++be converted into a proper ffmpeg display module.
++
++
++Decoder
++-------
++
++The decoder is a modified version of the existing ffmpeg hevc decoder.
++Generally it is ~100% faster than the existing ffmpeg hevc s/w decoder.
++More complex bitstreams can be up to ~200% faster but particularly easy
++streams can cut its advantage down to ~50%.  This means that a Pi3+ can
++display nearly all 8-bit 1080p30 streams and with some overclocking it can
++display most lower bitrate 10-bit 1080p30 streams - this latter case is
++not helped by the requirement to downsample to 8-bit before display on a
++Pi.
++
++It has had co-processor offload added for inter-pred and large block
++residual transform.  Various parts have had optimized ARM NEON assembler
++added and the existing ARM asm sections have been profiled and
++re-optimized for A53. The main C code has been substantially reworked at
++its lower levels in an attempt to optimize it and minimize memory
++bandwidth. To some extent code paths that deal with frame types that it
++doesn't support have been pruned.
++
++It outputs frames in Broadcom Sand format. This is a somewhat annoying
++layout that doesn't fit into ffmpegs standard frame descriptions. It has
++vertical stripes of 128 horizontal pixels (64 in 10 bit forms) with Y for
++the stripe followed by interleaved U & V, that is then followed by the Y
++for the next stripe, etc. The final stripe is always padded to
++stripe-width. This is used in an attempt to help with cache locality and
++cut down on the number of dram bank switches. It is annoying to use for
++inter-pred with conventional processing but the way the Pi QPU (which is
++used for inter-pred) works means that it has negligible downsides here and
++the improved memory performance exceeds the overhead of the increased
++complexity in the rest of the code.
++
++Frames must be allocated out of GPU memory (as otherwise they can't be
++accessed by the co-processors). Utility functions (in rpi_zc.c) have been
++written to make this easier. As the frames are already in GPU memory they
++can be displayed by the Pi h/w without any further copying.
++
++
++Known non-features
++------------------
++
++Frame allocation should probably be done in some other way in order to fit
++into the standard framework better.
++
++Sand frames are currently declared as software frames, there is an
++argument that they should be hardware frames but they aren't really.
++
++There must be a better way of auto-selecting the hevc_rpi decoder over the
++normal s/w hevc decoder, but I became confused by the existing h/w
++acceleration framework and what I wanted to do didn't seem to fit in
++neatly.
++
++Display should be a proper device rather than a kludge in ffmpeg.c
