15:48:50 2006 +0100 +Subject: [PATCH] Add flush_buffer() operation to uart_ops + +Serial drivers using DMA (like the Atmel USART3 driver) tend to get +very confused when the xmit buffer is flushed and nobody told them. +They also tend to spew a lot of garbage since the DMA engine keeps +running after the buffer is flushed and possibly refilled with +unrelated data. + +This patch adds a new flush_buffer operation to the uart_ops struct, +along with a call to it from uart_flush_buffer() right after the xmit +buffer has been cleared. The driver can implement this in order to +syncronize its internal DMA state with the xmit buffer when the buffer +is flushed. + +--- + + Documentation/serial/driver | 11 +++++++++++ + drivers/serial/serial_core.c | 2 ++ + include/linux/serial_core.h | 1 + + 3 files changed, 14 insertions(+) + +Index: linux-2.6.16-avr32/Documentation/serial/driver +=================================================================== +--- linux-2.6.16-avr32.orig/Documentation/serial/driver 2006-03-20 06:53:29.000000000 +0100 ++++ linux-2.6.16-avr32/Documentation/serial/driver 2006-04-03 18:57:11.000000000 +0200 +@@ -186,6 +186,17 @@ hardware. + Locking: port_sem taken. + Interrupts: caller dependent. + ++ flush_buffer(port) ++ Flush any write buffers, reset any DMA state and stop any ++ ongoing DMA transfers. ++ ++ This will be called whenever the port->info->xmit circular ++ buffer is cleared. ++ ++ Locking: port->lock taken. ++ Interrupts: locally disabled. ++ This call must not sleep ++ + set_termios(port,termios,oldtermios) + Change the port parameters, including word length, parity, stop + bits.

network device driver for the Atmel MACB interface, which +is present on the AT32AP7000 device from Atmel. I think it's basically +the same as the EMAC interface on AT91, so it should possibly be +merged with the at91_ether driver some time in the future. At the +moment, however, the at91_ether driver has quite a lot of at91- +specific dependencies so it's hard to reuse on AVR32. + +This is basically the same patch as the one distributed with the +AT32STK1000 BSP version 1.0, converted to use platform_device and +struct clk instead of at32_device. + +--- + drivers/net/Kconfig | 11 + drivers/net/Makefile | 2 + drivers/net/macb.c | 1159 +++++++++++++++++++++++++++++++++++++++++++++++++++ + drivers/net/macb.h | 387 +++++++++++++++++ + 4 files changed, 1559 insertions(+) + +Index: linux-2.6.18-avr32/drivers/net/Kconfig +=================================================================== +--- linux-2.6.18-avr32.orig/drivers/net/Kconfig 2006-11-02 14:16:07.000000000 +0100 ++++ linux-2.6.18-avr32/drivers/net/Kconfig 2006-11-02 14:17:29.000000000 +0100 +@@ -185,6 +185,17 @@ config MII + or internal device.

The AVR32 architecture is not binary +compatible with earlier 8-bit AVR architectures. + +The AVR32 architecture, including the instruction set, is described by the +AVR32 Architecture Manual, available from + +http://www.atmel.com/dyn/resources/prod_documents/doc32000.pdf + +The Atmel AT32AP7000 is the first CPU implementing the AVR32 architecture. It +features a 7-stage pipeline, 16KB instruction and data caches and a full +Memory Management Unit. It also comes with a large set of integrated +peripherals, many of which are shared with the AT91 ARM-based controllers from +Atmel. + +Full data sheet is available from + +http://www.atmel.com/dyn/resources/prod_documents/doc32003.pdf + +while the CPU core implementation including caches and MMU is documented by +the AVR32 AP Technical Reference, available from + +http://www.atmel.com/dyn/resources/prod_documents/doc32001.pdf + +Information about the AT32STK1000 development board can be found at + +http://www.atmel.com/dyn/products/tools_card.asp?tool_id=3918 + +including a BSP CD image with an earlier version of this patch, development +tools (binaries and source/patches) and a root filesystem image suitable for +booting from SD card. + +Alternatively, there's a preliminary "getting started" guide available at +http://avr32linux.org/twiki/bin/view/Main/GettingStarted which provides links +to the sources and patches you will need in order to set up a cross-compiling +environment for avr32-linux. + +This patch, as well as the other patches included with the BSP and the +toolchain patches, is actively supported by Atmel Corporation. +
