morris	6d46cf739c	feat(gdma): test non-cacheable DMA descriptor ... To avoid different DMA descriptors reside in the same cache line, we want the CPU to access the DMA descriptor in a non-cachable way	2023-07-25 10:59:07 +08:00
morris	57879e772d	feat(gdma): support channel allocator on esp32p4 ... There's two GDMA groups on ESP32P4, one is connected to AHB bus, and another one is connected AXI bus. We now have two seperate APIs for allocating DMA channels, depends on the bus type.	2023-07-19 18:18:07 +08:00
morris	56a376c696	feat(esp_gdma): add hal interface for common operations ... GDMA driver will be adapted to more DMA peripherals in the future. This commit is to extract a minimal interface in the hal layer	2023-07-10 13:45:57 +08:00
morris	da3b3cf4a4	dma: use ccomp_timer component for testing performance metric ... ccomp_timer now becomes a standalone component, located in the component registry. we can use that in the test app by component manager.	2023-05-04 14:09:36 +08:00
morris	dbca74f1ef	gdma: prevent mutli-channels connect to the same peripheral ... 1. add check in the gdma driver, to prevent multiple channels connecting to the same peripheral 2. memory copy DMA ID will occupy the peripheral's DMA ID on some ESP targets (e.g. esp32c3/s3). We should search for a free one when install async memcpy driver. Closes https://github.com/espressif/esp-idf/issues/10575	2023-01-31 15:18:19 +08:00
