2019-04-27udp: fix GRO reception in case of length mismatchPaolo Abeni1-4/+5
Currently, the UDP GRO code path does bad things on some edge conditions - Aggregation can happen even on packet with different lengths. Fix the above by rewriting the 'complete' condition for GRO packets. While at it, note explicitly that we allow merging the first packet per burst below gso_size.

Fragments may contain data from other records so we have to account for that when we calculate the destination and max length of copy we can perform.

Add support for saving and restoring DSP context in D3 to host DDR. The suspend callback includes: suspend all pcm's stream that are running, send CTX_SAVE ipc, drop all ipc's, release trace dma and then power off the DSP. And the resume callback performs the following steps: load FW, run FW, re-initialize trace, restore pipeline, restore the kcontrol values and finally send the ctx restore ipc to the dsp. The streams that are suspended are resumed by the ALSA resume trigger. If the streams are paused during system suspend, they are marked explicitly so they can be restored during PAUSE_RELEASE.

This patch adds support for real-time DSP logging (timestamped events and bespoke binary data) for firmware debug. The current solution relies on DMA transfers to system memory that is then accessed by userspace tools such as sof-logger. For Intel platforms, two types of DMAs are currently used (GP-DMA for Baytrail/CherryTrail and HDaudio DMA for SKL+) Due to historical reasons, the driver code follows the DSP firmware conventions and refers to 'traces', but it is currently unrelated to the Linux trace subsystem.

SOF exposes regular ALSA Kcontrols that are defined by topology. This patch converts the Kcontrol IO to DSP IPC. The current implementation is aligned with previous Intel solutions, but is not optimal and can be improved: a) for every get/put the host wakes up the DSP and generates an IPC. The kernel should cache the values and generate an IPC only when strictly necessary. b) the firmware can be implemented to only instantiate the pipelines and related control-related parts that are needed at a given time, and power-gate the relevant SRAM blocks. The development tasks for these two improvements has started, once validated they will be provided in an update.
