+1. Both ir-kbd-i2c and lirc_zilog provide support for RX events for
|
|
|
+the chips supported by lirc_zilog. Before moving lirc_zilog out of staging:
|
|
|
+
|
|
|
+a. ir-kbd-i2c needs a module parameter added to allow the user to tell
|
|
|
+ ir-kbd-i2c to ignore Z8 IR units.
|
|
|
+
|
|
|
+b. lirc_zilog should provide Rx key presses to the rc core like ir-kbd-i2c
|
|
|
+ does.
|
|
|
+
|
|
|
+
|
|
|
+2. lirc_zilog module ref-counting need examination. It has not been
|
|
|
+verified that cdev and lirc_dev will take the proper module references on
|
|
|
+lirc_zilog to prevent removal of lirc_zilog when the /dev/lircN device node
|
|
|
+is open.
|
|
|
+
|
|
|
+(The good news is ref-counting of lirc_zilog internal structures appears to be
|
|
|
+complete. Testing has shown the cx18 module can be unloaded out from under
|
|
|
+irw + lircd + lirc_dev, with the /dev/lirc0 device node open, with no adverse
|
|
|
+effects. The cx18 module could then be reloaded and irw properly began
|
|
|
+receiving button presses again and ir_send worked without error.)
|
|
|
+
|
|
|
+
|
|
|
+3. Bridge drivers, if able, should provide a chip reset() callback
|
|
|
+to lirc_zilog via struct IR_i2c_init_data. cx18 and ivtv already have routines
|
|
|
+to perform Z8 chip resets via GPIO manipulations. This would allow lirc_zilog
|
|
|
+to bring the chip back to normal when it hangs, in the same places the
|
|
|
+original lirc_pvr150 driver code does. This is not strictly needed, so it
|
|
|
+is not required to move lirc_zilog out of staging.
|
|
|
+
|
|
|
+Note: Both lirc_zilog and ir-kbd-i2c support the Zilog Z8 for IR, as programmed
|
|
|
+and installed on Hauppauge products. When working on either module, developers
|
|
|
+must consider at least the following bridge drivers which mention an IR Rx unit
|
|
|
+at address 0x71 (indicative of a Z8):
|
|
|
+
|
|
|
+ ivtv cx18 hdpvr pvrusb2 bt8xx cx88 saa7134
