whitequark b0361111d7 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 a8615cdbcf firmware: globally enable LTO. 
This used to crash with earlier rustc versions, but doesn't anymore,
and gives significant speedup (e.g. 2x on test_dma_record_time).
 2018-08-12 19:11:48 +00:00
whitequark 5da45f9486 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.

Sebastien Bourdeauducq bbe36b94f7 ad9154: enable sync in init 2018-08-06 19:02:27 +08:00
Sebastien Bourdeauducq 7f0b2ff594 jesd204sync: work around HMC7043 poor behavior with combined delays 
The HMC7043 outputs poorly controlled signals when adjusting
two delays at once. This commit puts the DAC in one-shot SYSREF mode,
and only triggers synchronizations when SYSREF is stable.

Sebastien Bourdeauducq f32f0126e2 Revert "ad9154: use continuous sync mode"

Sebastien Bourdeauducq b023865b42 sayma: instantiate dummy IBUFDS_GTE3 on unused but driven Si5324 clock pins 
Solve same problem as e83ee3a0 but channels cannot be independently disabled.
 2018-08-05 23:02:41 +08:00
Sebastien Bourdeauducq e83ee3a07a hmc7043: disable GTP_CLK1 when not in use 
Termination and biasing are not active at the FPGA when IBUFDS_GTE3 is
not instantiated, and driving a clock then leads to overvoltage.

Chris Ballance 47740c8930 share moninj injection state between dashboards 
Previously if one dashboard overrode a channel this was not visible on
any other dashboard - the channel appeared to operate normally.

David Nadlinger 829fca6112 pyon: Correctly deserialize bare NaNs

Previously, accidentally storing a NaN in a dataset would
bring down large parts of the system.

David Nadlinger 08ee91beb2 ad9910: Clarify chip_select range [nfc] 
`assert 3 <= chip_select <= 7` is rather opaque without looking
at the CPLD source code otherwise.

David Nadlinger 6b89106578 ad53xx: Avoid sporadic RTIOUnderflow in init() 
I observed sporadic RTIO underflows on Kasli before, by ~2.5 µs,
so 5 µs extra slack should be plenty. No underflows since.

Sebastien Bourdeauducq e4d48a78eb drtio: wait for remote to ack TSC synchronization 
Sayma takes a long time after TSC sync to align SYSREF, and this caused two issues:
1. Aux packets getting lost and causing error reports
2. DRTIO links reported up and kernels proceeding despite the DACs not being properly synced.
