whitequark b6e2613f77 runtime: avoid spurious error messages. 2015-08-07 11:03:36 +03:00
whitequark b5cf1e395d runtime: avoid race condition when running kernel. 
Also, don't bother passing kernel name: entry point is already
recorded in DT_INIT when the kernel is linked.

whitequark 98cd4288c1 artiq_personality: cast exception params so that %lld is always valid. 2015-08-06 08:25:53 +03:00
whitequark 722dfef97b artiq_personality: simplify. 2015-08-06 07:59:15 +03:00
whitequark 62fdc75d2d Integrate libdyld and libunwind. 
It is currently possible to run the idle experiment, and it
can raise and catch exceptions, but exceptions are not yet
propagated across RPC boundaries.

whitequark 6db93b34e8 artiq_personality: port to device. 2015-08-02 06:34:11 +03:00
whitequark aae2923c4c runtime: add lognonl{,_va} functions. 
The kernels have print(), which prints aggregates (such as
arrays) piece-by-piece, and newlines would interfere.

whitequark cd294e2986 artiq_personality: avoid unaligned loads. 2015-08-02 06:28:58 +03:00

whitequark c40ae9dbd3 MiSoC is not built with -fPIC anymore, remove support code for that. 2015-07-29 12:40:46 +03:00
Robert Jördens 67715f0d2e pipistrello: only put serdes on the lower ttls 
this setup is getting a bit power hungry.

pmt0, 1 (rtio channels 0, 1): 4x in and out
ttl0, 1 (rtio channels 2, 3): 4x out
ttl2 (rtio channel 4): 8x out

Robert Jördens 9dfbf07743 pipistrello: use 4x serdes for rtio ttl 
pipistrello: do not wait for lock on startup

LCK_cycle:6 was added in 6a412f796e1 (mibuild). It waits for _all_
DCM and PLLs to lock (probably irrespective of STARTUP_WAIT).

to test the Python parts without pulling in misoc.
