skeleton: Use ioctl gpio handling

2019-04-10T01:44:48+00:00

Now that chassiskill is a standalone app and is using ioctl gpio handling (through the gpioplus library), the gpio libraries here need to use ioctl as well for chassiskill to be compatible. Tested: Verified chassiskill works as intended and checked that nothing else broke. Change-Id: I67c431027d31e87c332c3e1771fc2d3423f56652 Signed-off-by: Anthony Wilson

Remove unnecessary args from GPIO functions

2018-08-14T20:42:00+00:00

Now that gpio_init() and read_gpios() doesn't use D-Bus, they don't need the D-Bus connection parameter. Change-Id: Id7f3ee6547bed7c0c0eed5d75cba2d6ff239d0fa Signed-off-by: Matt Spinler

Remove host control GPIOs from GpioConfigs

2018-08-14T20:42:00+00:00

These are not used anymore. Change-Id: I4bf8f0538aafeec768075fd51236a50f1f97b3d8 Signed-off-by: Matt Spinler

Fill in the function that finds the GPIO base

2018-08-14T20:42:00+00:00

Finds the GPIO base value to use in the GPIO number calculation. This is most likely specific to ASPEED BMCs, though as with the calling code additional support can be added in the future if required. Change-Id: Ie0d2b87286ab4bf6b05b61245bd821ab2a9d602a Signed-off-by: Matt Spinler

Fill in function to convert GPIO pin to a number

2018-08-14T20:42:00+00:00

Convert the pin, like "A7" to the number that identifies that GPIO in /sys/class/gpio/. This most likely only supports ASPEED BMCs, though of course support can be added for others if the need arises and this code is still in use.

Use cJSON to get the GPIO definitions

2018-08-14T20:42:00+00:00

In gpio_init, read the GPIO definitions out of the JSON instead of D-Bus. As many applications configure several GPIOs at once, the cJSON structure for the GPIOs stays loaded in memory until explicitly freed by calling gpio_inits_done().

Use cJSON to read the GPIO configuration

2018-08-14T20:42:00+00:00

Change the read_gpios function to get the power GPIO configuration out of JSON instead of D-Bus. Note that the Host Control GPIOs are no longer used and will be removed from the GpioConfigs structure in a future commit.

Add documentation on GPIO JSON

2018-08-14T20:42:00+00:00

Document the JSON format for the GPIO configuration. Change-Id: I74f9300f480724615ff031a7c75973224c86a760 Signed-off-by: Matt Spinler

Add function to load in the GPIO data from JSON.

2018-08-14T20:42:00+00:00

Use the cJSON module to load in the GPIO definitions used by the other skeleton code into a cJSON structure. Its memory should be released by calling cJSON_Delete on it when complete. This is the first commit in a series that will move the GPIO configuration data from D-Bus into a JSON file, which is both more appropriate for read only data and the first step in getting rid of the system_manager.py file that currently hosts it.

hostctl: Move to kernel FSI interface

2018-08-13T14:33:13+00:00

The Power8 systems now use the in-kernel FSI driver, so the GPIOs used for bitbanging are not available. This modifies the FSI SBE startup code to use the kernel FSI infrastructure. Change-Id: Ie7f7faab6af89b4311734eae4e252485a2163764 Signed-off-by: Joel Stanley
