occheung af263ffe1f ksupport: fix rpc, cache signature (FFI) 
The reason of the borrow stuff is explained in M-Labs/artiq-zynq#76 (artiq-zyna repo).
As for `cache_get()`, compiler will perform stack allocation to pre-allocate the returned structure, and pass to cache_get alongside the `key`.
However, ksupport fails to recognize the passed memory, so it will always assume the passed memory as the key.

VexRiscv seems to not support additional hardware performance counter, at least I have not seen any documentation on how to use it.

David Nadlinger d95e619567 compiler: Implement binary NumPy math functions (arctan2, …) 
The bulk of the diff is just factoring out the implementation
for binary arithmetic implementations, to be reused for binary
function calls.

David Nadlinger bc6fbecbda compiler, firmware: Do not expose abort() to kernels 
This was only exposed for the assert implementation, and
does not exist on Zynq.

David Nadlinger 8e30c4574b firmware: Treat timestamps consistently as signed [nfc] 
This matches other functions and the ARTIQ Python side, but
isn't actually an ABI change.

David Nadlinger d4c393b2a8 firmware/ksupport: Update `cfg(not(has_rtio))` stub signatures 
This fixes up 8caea0e6d3,
but it is unclear whether anyone even uses a `not(has_rtio)`
configuration at this point.

whitequark 38d60100ff firmware: optimize dma_record_output. 
This removes a number of bounds checks and adds a fast path for
outputting exactly one word to DMA, which is the most common
operation.

whitequark 2648b1b7a1 firmware: migrate to Rust 1.28.0. 
This also updates / is a prerequisite for updating smoltcp.

Rationale for changes made:
  * compiler_builtins is now shipped in the rust prefix.
  * rustc's libpanic_unwind no longer works for us because it
    has a hard dependency on Box (and it's a horrible hack);
    fortunately, we only ever needed a personality function
    from it.
  * panic and oom handlers are now set in a completely different
    way.
  * allocators are quite different (and finally stable).
  * NLL caused internal compiler errors in runtime, so code using
    NLL was rewritten to not rely on it and it was turned off.

whitequark a74958f01f ksupport: raise RuntimeError on reraise with no inflight exception. 
Fixes #1123.
 2018-08-07 05:53:13 +00:00
whitequark b6dd9c8bb0 runtime: support builds without RTIO DMA. 
Fixes #1079.

whitequark 31c6c79204 firmware: implement an edge profiler. 
It doesn't work extremely well, and the results can be somewhat
confusing, and it needs a libunwind patch, but it's the best I could
do and it seems still useful.

whitequark b54926134c firmware: update the signature of #[lang="panic_fmt"]. 2018-05-15 15:05:19 +00:00

whitequark 140ca729aa firmware: rename io::Error::{UnexpectedEof→UnexpectedEnd}. 
We don't even have files.

whitequark ce0593315b firmware: move {ProtoRead,ProtoWrite} to the root of libio. 2018-05-15 08:16:09 +00:00
whitequark ae50196186 firmware: rename libproto to libproto_artiq. 
libproto_artiq only has ARTIQ-specific protocols.
 2018-05-14 18:09:44 +00:00
whitequark 02b8426f60 firmware: rename libboard to libboard_misoc. 
By analogy with libbuild_misoc. Hopefully one day it actually gets
moved to misoc...
 2018-05-14 18:09:44 +00:00
whitequark 1ff42683d9 firmware: merge libamp into libboard_artiq. 
All gateware interfaces live in libboard_artiq, but libamp predates
libboard_artiq.
 2018-05-14 17:33:25 +00:00
whitequark 6a10d54432 firmware: migrate rpc_proto to new libio. 
This closes an old and horrible issue in that some code in ksupport
may implicitly try to allocate and we'll never know until it crashes
at runtime inside liballoc_stub.

This also removes liballoc_stub.
This also removes ReadExt and WriteExt from libproto.
Hooray!
