2024-05-06ASoC: Intel: avs: clarify Copyright informationPierre-Louis Bossart
For some reason a number of files included the "All rights reserved" statement. Good old copy-paste made sure this mistake proliferated. Remove the "All rights reserved" in all Intel-copyright to align with internal guidance.

2024-04-19ASoC: Intel: avs: New IRQ handling implementationCezary Rojewski
The existing code can be both improved and simplified. To make this change easier to manage, first add new implementation and then remove deadcode in a separate patch. Simplification achieved with: - reduce the amount of resources requested by the driver i.e.: IPC and CLDMA request_irq() merged into one - reduce the number of DSP ops from 2 to 1: irq_handler/thread() vs dsp_interrupt() - drop ambiguity around CLDMA interrupt, let skl.c handle that explicitly as it is the only user Signed-off-by: Cezary Rojewski <cezary.rojewski@intel.com> Link: https://lore.kernel.org/r/20240419084857.2719593-2-cezary.rojewski@intel.com Signed-off-by: Mark Brown <broonie@kernel.org>
2023-09-29ASoC: Intel: avs: Use generic size definesAmadeusz Sławiński
Instead of using PAGE_SIZE as base of definitions in headers, use generic size defines. While x86 platforms use 4096 as page size, there are platforms which use different page sizes. Two of changed defines are for memory windows on DSP side, which have fixed size independent of host side page size. Another one is for CLDMA buffer which also doesn't need to change with page size.

2022-03-11ASoC: Intel: avs: Implement CLDMA transferCezary Rojewski
SKL and KBL rely on a dedicated HDAudio DMA stream for code loading and authentication. The implementation of this specific mechanism for SKL-based platforms re-uses HDAudio DMA (streaming) functions found in HDA library to avoid duplication of functionality.
