linuswck bb0b8a6c00 kasli: Correct the GTP TX clock path during init 
- TXOUT must be fed back into TXUSRCLK during initialization
- Now, MMCM Clock Input is switched before GTP TX Init is started instead of after GTP TX Init is done
- Reset in Sys Clock domain is kept asserted when clock is switched and GTP TX Init is NOT done

They are now a reply for DestinationStatusRequest.
This prevents gateware errors and lost packets if the receiver is busy.

David Nadlinger efbae51f9d runtime: Validate ksupport ELF against hard-coded address ranges 
This would have caught the reduction in header padding with LLD 14.
In theory, we could just get rid of the hard-coded kernel CPU address
ranges altogether and use ksupport.elf as the one source of truth; the
code already exists in dyld. The actual base address of the file would
still need to be forwarded to the kernel-side libunwind glue, though,
as there doesn't seem to be a clean way to get the equivalent of
KSUPPORT_HEADER_SIZE through the linker script. I have left this as-is
with the hard-coded KERNELCPU_… constants for now.

David Nadlinger 8acfa82586 ksupport: Remove unused sections from linker script [nfc] 
We no longer build ksupport.ld in a position-independent fashion, and
the reference to the ld.bfd _GLOBAL_OFFSET_TABLE issue was just a
distraction
 2023-08-07 10:10:38 +00:00
David Nadlinger 4d636ea593 Upgrade to LLD 14 
Previous linker versions had inserted some zero padding bytes
between the ELF headers and the first section, but LLD 14 does
not anymore.

Hard-coding the offset of the first section in ksupport.elf
manually isn't ideal; we should probably parse the ELF program
headers instead when first setting up the kernel CPU.

sven-oxionics b3dc199e6a Fix panic when receiving empty strings in rpc calls 
Receiving an empty string in an RPC call currently panics.

When `length` is zero, a call to the `alloc` function (as implemented in `artiq/firmware/runtime/session.rs`) returns a null pointer. Constructing a `CMutSlice` from a null pointer panics.
A `CMutSlice` consists of a pointer and the length. Rust's documentation of the `core::ptr` module states: "The canonical way to obtain a pointer that is valid for zero-sized accesses is `NonNull::dangling`."
This commits adds a check for the length of a string received in an RPC call. Only for lengths greater than zero a memory allocation is performed. For zero-length strings, a dangling pointer is used.

Test plan:
Invoke the following experiment, which returns an empty string over RPC:
```
class ReturnEmptyString(artiq.experiment.EnvExperiment):
    def build(self):
        self.core: Core = self.get_device("core")

    @kernel
    def run(self):
        x = self.do_rpc()
        print(x)

    @rpc
    def do_rpc(self) -> TStr:
        return ""
```
