: if( psz_cache )
: uint8_t p_sector[DVDCSS_BLOCK_SIZE];
: i_ret = dvdcss->pf_read( dvdcss, p_sector, 1 );
: Can leave p_sector not aligned suitably for DMA in gcc-4 ? (pf_read
:winds up calling read on the DVD device with p_sector as the buffer).
It's a roll of dice, really. Neither gcc-3 nor gcc-4 guarantee any
sort of alignment for a char array, and our kernel's physio() doesn't
realign the data.
Well, I guess since nobody has bitten on fixing physio() I'll have to
do it myself :-). I'll do it today.
