Broadwell: IPC errors #288

that error in itself shows legacy is likely broken. |
|
platforms must be broken if nobody is using it. :( |
it's somewhat confusing here, but for legacy, stream_tag is not used, so that looks fine. |
|
Unfortunately this feels like a total failure on all legacy platforms, I also have a DSP panic on Baytrail after the trace is initialized. Am I the only one to test? |
|
@keqiaozhang There is a a DSP panic on Baytrail. see also issues #443 for more details. dmesg: |
|
Looking at thesofproject/sof#443, do I understand correctly that Baytrail has not booted since September 29? If yes, does anyone have a test report of a working configuration? I am not sure how anyone can fix this without this information - or it'll be just debugging in complete darkness. |

@xiulipan ok, but that doesn't answer to my second question... What is the most recent configuration of (kernel, sof, soft) where legacy platforms worked? |
|

I think we can make APL and BYT health at first, then check the BDW. |

Offset into the page should also be considered while calculating a physical address for struct dma_debug_entry. page_to_phys() just shifts the value PAGE_SHIFT bits to the left so offset part is zero-filled. An example (wrong) debug assertion failure with CONFIG_DMA_API_DEBUG enabled which is observed during systemd boot process after recent dma-debug changes: DMA-API: e1000 0000:00:03.0: cacheline tracking EEXIST, overlapping mappings aren't supported WARNING: CPU: 4 PID: 941 at kernel/dma/debug.c:596 add_dma_entry CPU: 4 UID: 0 PID: 941 Comm: ip Not tainted 6.12.0+ #288 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.16.2-debian-1.16.2-1 04/01/2014 RIP: 0010:add_dma_entry kernel/dma/debug.c:596 Call Trace: <TASK> debug_dma_map_page kernel/dma/debug.c:1236 dma_map_page_attrs kernel/dma/mapping.c:179 e1000_alloc_rx_buffers drivers/net/ethernet/intel/e1000/e1000_main.c:4616 ...

DSP startup fails with IPC errors. Looks like the trace is broken - again 👎
