Try only to realise the truth : Comment 149 of 335 | ANN.lu |
Posted by priest on 05-Jul-2004 12:22 GMT | In reply to Comment 144 (Anonymous): " Is an unreliable cache coherency support a feature ? "
I do not know what it is untill the OS is updated/written to TRY to make it reliable, it is being done for AOS4. (apparently not for Linux and not for Linux/OpenBSD/MOS + peg1 without April)
Then it perhaps becomes a "SW cache coherency" -feature on AOS4 but a unsupported cache coherency feature (or "unreliable cache coherency" feature) on Linux (and on peg1 without April). ;-)
BUT, if it still fails, it might morph to a "SW bug to be fixed", etc etc... untill SW developers give up (-> it's a HW bug) or untill no one any more finds glitches in data transfer ("SW cache coherency" -feature).
(if the functionality is result of MAI's attempt to gain some new advantage over the competition, it would have been wise to make it optional so that traditional HW cache coherency would work... but nowdays it seems that MAI was just not too smart in general...) |
