[PATCH 0/4] hw/dma: Align SiFive PDMA behavior with real hardware

Posted by frank.chang@sifive.com 2 years, 7 months ago

From: Frank Chang <frank.chang@sifive.com>

Current QEMU PDMA doesn't align with real PDMA's behavior. This would
result in Linux dmatest failed. This patchest aligns with real PDMA's
behavior we tested on the real board. The golden results are performed
in U-boot on the Unmatched board with PDMA supported.

Frank Chang (3):
  hw/dma: sifive_pdma: reset Next* registers when Control.claim is set
  hw/dma: sifive_pdma: claim bit must be set before DMA transactions
  hw/dma: sifive_pdma: don't set Control.error if 0 bytes to transfer

Green Wan (1):
  hw/dma: sifive_pdma: allow non-multiple transaction size transactions
