832 comment "Speed Optimizations"
833 config BFIN_INS_LOWOVERHEAD
834 bool "ins[bwl] low overhead, higher interrupt latency"
837 Reads on the Blackfin are speculative. In Blackfin terms, this means
838 they can be interrupted at any time (even after they have been issued
839 on to the external bus), and re-issued after the interrupt occurs.
840 For memory - this is not a big deal, since memory does not change if
843 If a FIFO is sitting on the end of the read, it will see two reads,
844 when the core only sees one since the FIFO receives both the read
845 which is cancelled (and not delivered to the core) and the one which
846 is re-issued (which is delivered to the core).
848 To solve this, interrupts are turned off before reads occur to
849 I/O space. This option controls which the overhead/latency of
850 controlling interrupts during this time
851 "n" turns interrupts off every read
852 (higher overhead, but lower interrupt latency)
853 "y" turns interrupts off every loop
854 (low overhead, but longer interrupt latency)
856 default behavior is to leave this set to on (type "Y"). If you are experiencing
857 interrupt latency issues, it is safe and OK to turn this off.

1101 One well known example of this is PCMCIA- or PC-cards, credit-card
1102 size devices such as network cards, modems or hard drives which are
1103 plugged into slots found on all modern laptop computers. Another
1104 example, used on modern desktops as well as laptops, is USB.
1106 Enable HOTPLUG and build a modular kernel. Get agent software
1107 (from <http://linux-hotplug.sourceforge.net/>) and install it.
1108 Then your kernel will automatically call out to a user mode "policy
1109 agent" (/sbin/hotplug) to load modules and set up software needed
1110 to use devices as you hotplug them.

1138 Sleep "Deeper" Mode (High Power Savings) - This mode reduces dynamic
1139 power dissipation by disabling the clock to the processor core (CCLK).
1140 Furthermore, Standby sets the internal power supply voltage (VDDINT)
1141 to 0.85 V to provide the greatest power savings, while preserving the
1143 The PLL and system clock (SCLK) continue to operate at a very low
1144 frequency of about 3.3 MHz. To preserve data integrity in the SDRAM,
1145 the SDRAM is put into Self Refresh Mode. Typically an external event
1146 such as GPIO interrupt or RTC activity wakes up the processor.
1147 Various Peripherals such as UART, SPORT, PPI may not function as
1148 normal during Sleep Deeper, due to the reduced SCLK frequency.
1149 When in the sleep mode, system DMA access to L1 memory is not supported.

1158 The PLL and system clock (SCLK), however, continue to operate in
1159 this mode. Typically an external event or RTC activity will wake

1209 the general-purpose wake-up enable (GPWE) control bit to enable
1210 wake-up upon detection of an active low signal on the /GPW (PH7) pin.
