- for test and demonstration, starting with
- dl11/dl11echo.mac: console interface echo tester
- sys/blink.mac: 'blinking lights' demo (rsx,bsd and other modes)
- retire tools/asm-11/w11 area
- 99-retro-usb-permissions.rules renamed to 90-retro-usb-permissions.rules
- 91-retro-usb-latency.rules: udev rule to enforce low latency for FDTI USB UART
- 92-retro-usb-persistent.rules: udev rule for persistent device names
- Note:
- for all FTDI USB-UART it is essential to set them to `low latency` mode.
That was default for linux kernels 2.6.32 to 4.4.52. Since about March
2017 one gets kernels with 16 ms default latency again, thanks to
kernel patch 9589541. For newer systems it is essential to install the
udev rule which automatically sets low latency.
- document urjtag build (jtag in Ubuntu 16.04 is broken)
- add environment sanity wrappers for acroread,awk,firefox to ensure
proper operation of vivado under Ubuntu 16.04
