[PATCH v2 00/11] hw/char/pl011: Implement TX (async) FIFO to avoid blocking the main loop

Posted by Philippe Mathieu-Daudé 10 months, 1 week ago

Hi,

This series add support for (async) FIFO on the transmit path
of the PL011 UART.

Since v1:
- Restrict pl011_ops[] impl access_size,
- Do not check transmitter is enabled (Peter),
- Addressed Alex's review comments,
- Simplified migration trying to care about backward compat,
  but still unsure...

Philippe Mathieu-Daudé (11):
  hw/char/pl011: Restrict MemoryRegionOps implementation access sizes
  hw/char/pl011: Display register name in trace events
  hw/char/pl011: Remove duplicated PL011_INT_[RT]X definitions
  hw/char/pl011: Replace magic values by register field definitions
  hw/char/pl011: Split RX/TX path of pl011_reset_fifo()
  hw/char/pl011: Extract pl011_write_txdata() from pl011_write()
  hw/char/pl011: Extract pl011_read_rxdata() from pl011_read()
  hw/char/pl011: Warn when using disabled transmitter
  hw/char/pl011: Check if receiver is enabled
  hw/char/pl011: Rename RX FIFO methods
  hw/char/pl011: Implement TX FIFO
