GitHub147[milkymist-ng/master] Map DDR PHY controls in CSR - Sebastien Bourdeauducq16:40
lekernelwpwrak: yeah, the filesystem stuff is amazingly crappy16:41
lekernelI can't think of anything to defend it16:41
lekernellots of code duplication, lots of bugs, major design flaws (like lack of synchronization), lousy API, ...16:41
wpwrakheh, so there may be more fun waiting for us :)16:42
lekernelphew, don't bother16:42
lekernelunless you want to redesign the RTEMS filesystem from scratch :)16:43
lekernelseriously there's nothing good in it16:43
lekernelbetter spend that time on linux16:43
lekernelthe current solution.. somehow works16:44
wpwrakwell, that hang is kinda nasty. you can produce it by accident. let's see if it's easy to fix ...16:47
lekerneleven their main developers admit it's crappy and most of it is in that state due to historical accidents16:47
lekernelbut the redesign exceeds the available motivation16:47
wpwrakthat's sort of impressive in itself :)16:48
wpwrakan operating system without a working file system. erm ;-)16:48
HodappDOS was arguably that.16:50
Hodapp...so was whatever the OS was that Apple Newtons ran16:50
lekernelso, the canonical place for FJMEM is ${HOME}/.qi/milkymist/fjmem/fjmem.bit it seems?16:51
wpwrakis it ?16:59
wpwraki have it in $HOME/.qi/milkymist/release/2011-07-13/fjmem.bit and $HOME/.qi/milkymist/release/current/fjmem.bit17:00
Action: kristianpaul stick with bare-metal apps for now17:00
wpwrakand it probably should be in /usr{/local,}/share/something17:00
lekernel/usr/local/share/milkymist/fjmem.bit ?17:01
wpwrakthat sounds much cleaner to me, yes.17:08
lekernelcan you add it to m1nor?17:10
lekernelmaybe also with the /usr/share - if someday distros want to package fjmem by some miracle17:11
