2019-11-21tools/power/x86/intel-speed-select: Ignore missing config levelSrinivas Pandruvada2-5/+6
It is possible that certain config levels are not available, even if the max level includes the level. There can be missing levels in some platforms. So ignore the level when called for information dump for all levels and fail if specifically ask for the missing level. Here the changes is to continue reading information about other levels even if we fail to get information for the current level. But use the "processed" flag to indicate the failure. When the "processed" flag is not set, don't dump information about that level. Signed-off-by: Srinivas Pandruvada <[email protected]> Signed-off-by: Andy Shevchenko <[email protected]>

2019-11-07tools/power/x86/intel-speed-select: Support platform with limited Intel(R) ↵Srinivas Pandruvada4-60/+113
Speed Select There are some platforms, where there limited support of Intel(R) SST features. Here perf-profile has only one base configuration and limited support of commands. But still has support for discovery of base-freq and turbo-freq features. So it is important to show minimum features to use base-freq and turbo-freq features. Here the change are: - When there is no support of CONFIG_TDP_GET_LEVELS_INFO, then instead of treating this as fatal error, treat this with number of config levels = 0, that means only base level 0 is present. - There is no support of mail box commands to get base frequencies or turbo frequencies. Here present base frequency by reading cpufreq base freq and turbo frequency by reading MSR 0x1AD. - Don't display any field, which has value == 0.

We need to convert all old gpio irqchips to pass the irqchip setup along when adding the gpio_chip. For more info see drivers/gpio/TODO. For chained irqchips this is a pretty straight-forward conversion. This driver requests the IRQ directly in the driver so it needs to pass a NULL parent handler. We may revisit this code later and pull reqular shared IRQ handler into gpiolib, so leave a FIXME.

2019-10-15platform/mellanox: Add bootctl driver for Mellanox BlueField SocLiming Sun6-0/+496
This commit adds the bootctl platform driver for Mellanox BlueField Soc, which queries secure state and controls the eMMC boot partition swapping by sending SMC calls to ATF running at EL3. Below are the sequences of typical use case. 1. User requests boot partition swapping, which could be on-demand or during boot-image upgrade via UEFI capsule; 2. This bootctl driver handles the request and sends SMC call to ATF. ATF programs register BREADCRUMB0 which has value preserved during warm reset. It also programs eMMC to swap the boot partition; 3. After software reset (rebooting), ATF BL1 (BootRom) checks register BREADCRUMB0 and enable watchdog if configured; 4. If booting fails, the watchdog timer will trigger rebooting. In such case, ATF Boot ROM will switch the boot partition back to the previous one. This is a robust feature and used to prevent failure during boot partition upgrade.
