The SAMD core supports DMA, but this cannot be easily used from a library or sketch currently. In particular, multiple users of the DMA module need some coordination about what channels are in use, wh…

**Describe the bug**
The async_user_callback can be triggered from two places one from the DMA transfer complete interrupt generated by the DMA and from an k_work queue timeout.
This timeout is not …

The sink Stream in LiteDRAMDMAWriter has the 'ready' flag set by default.
If with_csr is set, shouldn't the 'sink.ready' flag only be set if the 'enable' bit is set in the CSR?
At the moment you…

There should be way for users to give a "hint" for these modules that a DMA transfer is preferred.
I call it a hint since a DMA transaction is not always available. The underlying controller / platfor…

I am running irqbalance on an embedded system, where the vast majority of interrupts are from platform devices. irqbalance makes an attempt to classify IRQs based on their name (`guess_arm_irq_hints`)…

### Describe the bug
I installed WSA_2407.40000.0.0_x64_Release-Nightly-with-magisk-b38ab2a7.27004.-canary-GApps-13.0-NoAmazon.7z but no application installed but if I installed WSA_2407.40000.0.0_x6…

When trying to allocate memory regions provided by vhost-user qemu protocol for DMA errors provided below are logged:
```bash

Zerocopy should also be supported for ehci controllers. At least ehci and ohci controllers must be detected and ensured that everything still works on these devices.
Idea:
check if devices's dma_mask…

### What happened?
Installed Riek's Ubuntu 24.04 (server edition) on NVME (could'nt get installed using rkdeveloptool). It starts up. But when I try to find the EMMC devices, there are none with lsbl…

The sustained DMA event rate is surprisingly low on Kasli. Using the below experiment, I find that shortest pulse-delay time without underflow for a TTL output is:
* Opticlock: 530mu
* DRTIO local T…
