This patch sets the config option CONFIG_MEMORY_HOTPLUG_DEFAULT_ONLINE=y for pseries and updates the pseries memory hotplug code so that DLPAR added memory can be automatically onlined instead of explicitly onlining the memory.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement new character device driver to allow access from user space to the operator panel display present on IBM Power Systems machines with FSPs. This will allow status information to be presented on the display which is visible to a user. The driver implements a character buffer which a user can read/write by accessing the device (/dev/op_panel). This buffer is then displayed on the operator panel display. Any attempt to write past the last character position will have no effect and attempts to write more characters than the size of the display will be truncated. The device may only be accessed by a single process at a time.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The TUNE_CELL option allows you to build a kernel that runs on multiple CPUs but is tuned (ie. optimised) to run on Cell CPUs. Now days no one is building a distro in that fashion, and any users who are building custom kernels for their Cell machines are better off building with CONFIG_CELL_CPU, which builds a kernel that only runs on Cell and therefore can be optimised even more aggresively. Dropping the option also avoids confusing other users, who are presented with an option to tune for Cell when they are not building for a Cell CPU at all.

Hardware and software options are separated, with the hope that other embedded platforms could share the software options, and to make it easier to maintain custom/alternate configs that focus on either hardware or software options. Due to the previous patch, this patch should not affect the results of any of the affected defconfigs -- only how those results are achieved. The resulting config is more or less the union of the options that any of the configs previously selected. No attempt was made in this (or the previous) patch to edit out questionable options, but this patch will make it easier to do so in future patches.

|/ | | | | | | | | | | | | | | | A working rtc kernel driver is needed so that hwclock can synchronize system clock to rtc during shutdown/boot. We already have a powernv platform rtc driver located at drivers/rtc/rtc-opal.c. However it depends on CONFIG_RTC_CLASS which is disabled by default. Hence the driver isn't enabled and not compiled for the powernv kernel. We fix this by enabling rtc class support in pseries defconfig which enables this driver and compiles it into the pseries kernel. In case CONFIG_PPC_POWERNV is not enabled we fallback to 'Generic RTC support' driver which emulates the legacy 'PC RTC driver'.

This method will require less maintenance in the future and will ensure that both 'defconfigs' are always in sync. It is worth noting that the seemingly more simple approach of: pseries_le_defconfig: pseries_defconfig $(Q)$(MAKE) le.config Will not work when building using O=builddir. The obvious fix to that: pseries_le_defconfig: $(Q)$(MAKE) -f $(srctree)/Makefile pseries_defconfig le.config Also does not work. This is because if we have for example: config FOO depends on CPU_BIG_ENDIAN select BAR Then BAR will be enabled by the first call to kconfig (via pseries_defconfig), and then will remain enabled after we merge le.config, even though FOO will have been turned off. The solution is to ensure to only invoke the kconfig logic once, after we have merged all the config fragments. This ensures nothing is select'ed on that should then be disabled by the later merged configs.
