Special ./configure options
In some situations Linux may deliver a better write performance to drives if
the track input is read with O_DIRECT (see man 2 open). The API call
burn_os_open_track_src() and the input readers of cdrskin and libburn fifo
can be told to use this peculiar read mode by:
--enable-track-src-odirect
But often libburn call burn_write_opts_set_dvd_obs(opts, 64*1024) will yield
even better performance in such a situation. 64k can be made default at
configure time by:
--enable-dvd-obs-64k
This may be combined with above --enable-track-src-odirect .
Make sure to re-compile all source files after running ./configure
make clean ; make
make install

/* ts A91016 : libburn/ecma130ab.c is the replacement for old libburn/lec.c
Copyright 2009, Thomas Schmitt <scdbackup@gmx.net>, libburnia-project.org
This code module implements the production of RSPC parity bytes (P- and Q-
parity) and the scrambling of raw CD-ROM sectors as specified in ECMA-130:
http://www.ecma-international.org/publications/files/ECMA-ST/Ecma-130.pdf
The following statements about Galois Fields have been learned mostly from
http://www.cs.utk.edu/~plank/plank/papers/CS-96-332.pdf
by James S. Plank after an e-mail exchange with Norbert Preining.
The output has been compared with the output of the old code of libburn
which was labeled "borrowed HEAVILY from cdrdao" and claimed by Joerg
Schilling to stem from code by Heiko Eissfeldt.
-------------------------------------------------------------------------
Note: In this text, "^" denotes exponentiation and not the binary exor
operation. Confusingly in the C code "^" is said exor.
Note: This is not C1, C2 which is rather mentioned in ECMA-130 Annex C and
always performed inside the drive.
-------------------------------------------------------------------------
RSPC resp. P- and Q-Parity
ECMA-130 Annex A prescribes to compute the parity bytes for P-columns and
Q-diagonals by RSPC based on a Galois Field GF(2^8) with enumerating
polynomials x^8+x^4+x^3+x^2+1 (i.e. 0x11d) and x^1 (i.e. 0x02).
Bytes 12 to 2075 of a audio-sized sector get ordered in two byte words
as 24 rows and 43 columns. Then this matrix is split into a LSB matrix
and a MSB matrix of the same layout. Parity bytes are to be computed
from these 8-bit values.
2 P-bytes cover each column of 24 bytes. They get appended to the matrix
as rows 24 and 25.
2 Q-bytes cover each the 26 diagonals of the extended matrix.
Both parity byte pairs have to be computed so that extended rows or
diagonals match this linear equation:
H x V = (0,0)
H is a 2-row matrix of size n matching the length of the V ectors
[ 1 1 ... 1 1 ]
[ x^(n-1) x^(n-2) x^1 1 ]
Vp represents a P-row. It is a byte vector consisting of row bytes at
position 0 to 23 and the two parity bytes which shall be determined
at position 24 and 25. So Hp has 26 columns.
Vq represents a Q-diagonal. It is a byte vector consisting of diagonal
bytes at position 0 to 42 and the two parity bytes at position 43 and 44.
So Hq has 45 columns. The Q-diagonals cover P-parity bytes.
By applying some high school algebra one gets the parity bytes b0, b1 of
vector V = (n_payload_bytes, b0 , b1) as
b0 = ( H[n] * SUM(n_payload_bytes) - H[0..(n-1)] x n_payload_bytes )
/ (H[n+1] - H[n])
b1 = - SUM(n_payload_bytes) - b0
H[i] is the i-the element of the second row of matrix H. E.g. H[0] = x^(n-1)
The result has to be computed by Galois field arithmetics. See below.
The P-parity bytes of each column get reunited as LSB and MSB of two words.
word1 gets written to positions 1032 to 1074, word0 to 1075 to 1117.
The Q-parity bytes of each diagonal get reunited too. word1 goes to 1118
to 1143, word0 to 1144 to 1169.
>>> I do not read this swap of word1 and word0 from ECMA-130 Annex A.
>>> But the new output matches the old output only if it is done that way.
>>> See correctness reservation below.
Algebra on Galois fields is the same as on Rational Numbers.
But arithmetics is defined by operations on polynomials rather than the
usual integer arithmetics on binary numbers.
Addition and subtraction are identical with the binary exor operator.
Multiplication and division would demand polynomial division, e.g. by the
euclidian algorithm. The computing path over logarithms and powers follows
algebra and allows to reduce the arithmetic task to table lookups, additions
modulo 255, and exor operations. Note that the logarithms are natural
numbers, not polynomials. They get added or subtracted by the usual addition
(not by exor) and their polynomial power depends on their value modulo 255.
Needed are a logarithm table and a power table (or inverse logarithm table)
for Galois Field GF(2^8) which will serve to perform the peculiar
multiplication and division operation of Galois fields.
The power table is simply an enumeration of x^n accorting to
GF-multiplication. It also serves as second line of matrix H for the parity
equations:
Hp[i] = gfpow[25-i] , i out of {0,..,25}
Hq[i] = gfpow[44-i] , i out of {0,..,44}
The logarithm table is the inverse permutation of the power table.
Some simplifications apply to the implementation:
In the world of Galois fields there is no difference between - and +.
The term (H[n+1] - H[n]) is constant: 3.
-------------------------------------------------------------------------
Scrambling
ECMA-130 Annex B prescribes to exor the byte stream of an audio-sized sector
with a sequence of pseudo random bytes. It mentions polynomial x^15+x+1 and
a 15-bit register.
It shows a diagram of a Feedback Shift Register with 16 bit boxes, though.
Comparing this with explanations in
http://www.newwaveinstruments.com/resources/articles/m_sequence_linear_feedback_shift_register_lfsr.htm
one can recognize the diagram as a Fibonacci Implementation. But there seems
really to be one bit box too many.
The difference of both lengths is expressed in function next_bit() by
the constants 0x3fff,0x4000 for 15 bit versus 0x7fff,0x8000 for 16 bits.
Comparing the output of both alternatives with the old scrambler output
lets 15 bit win for now.
So the prescription is to start with 15 bit value 1, to use the lowest bit
as output, to shift the bits down by one, to exor the output bit with the
next lowest bit, and to put that exor result into bit 14 of the register.
-------------------------------------------------------------------------
Correctness Reservation
In both cases, parity and scrambling, the goal for now is to replicate the
output of the dismissed old lec.c by output which is based on published
specs and own implementation code. Whether they comply to ECMA-130 is a
different question which can only be answered by real test cases for
raw CD recording.
Of course this implementation will be corrected so that it really complies
to ECMA-130 as soon as evidence emerges that it does not yet.

LG GH22LS30 revision 1.00 returns for DVD-R format

A MS-Windows tool can inquire media code "RITEKF1",
though.
This macro causes a try to unconditionally read the
desired payload bytes. The drive then returns 35
bytes as requested and the media id is "RITEKF1".
Nevertheless this is not a generally usable gesture
because older Linux USB dislikes requests to fetch
more bytes than the drive will deliver.

/* ts A91114 : EXPERIMENTAL, NOT COMPLETELY IMPLEMENTED
Simplified data transmission for DVD. libburn via Linux USB is 30 % slower
than growisofs or cdrecord when transmitting 32 KB chunks.
With 64 KB chunks it is 20% faster than the competitors.
No heavy CPU load is visible but there might be subtle race conditions in
the USB driver which work better with shorter time gaps between WRITE
commands.
Insight: It is actually about the interference of track source reading
with SCSI writing via USB. growisofs reads with O_DIRECT into a
mmap()ed buffer. When doing the same, libburn with 32 KB chunks
reaches similar write speed.
On the other hand, 64 KB chunks are 20% faster than that and
are not improved by reading O_DIRECT.
O_DIRECT is a property of the input fd of struct burn_source.
It can only be done with properly aligned memory and with aligned
read size. Alignment size is file system system specific.
System call
mmap(NULL, (size_t) buffer_size, PROT_READ | PROT_WRITE,
MAP_SHARED | MAP_ANONYMOUS, -1, (off_t) 0);
is supposed to allocate a properly aligned buffer.
64 KB is supposed to be a safe size.
Actually mmap() seems to be the main cause for a positive effect
of O_DIRECT.
This simplified transmission function did not bring visible benefit.
So for now it is not worth to teach it all applicable details of old
CD sector oriented transmission.
