| * at_hdmac: Rework suspend_late()/resume_early()Dan Williams2009-09-141-7/+12
| | | | | | | | | | | | | | | | | | | | | | | | This patch reworks platform driver power management code for at_hdmac from legacy late/early callbacks to dev_pm_ops. The callbacks are converted for CONFIG_SUSPEND like this: suspend_late() -> suspend_noirq() resume_early() -> resume_noirq() Signed-off-by: Dan Williams <dan.j.williams@intel.com> Signed-off-by: Rafael J.

| * PM: Reset transition_started at dpm_resume_noirqXiaotian Feng2009-09-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | transition_started should be set once the preparation of devices for a PM has started, reset before starting to resume devices. When resuming devices, kernel calls dpm_resume_noirq then dpm_resume_end(dpm_resume). Thus we should reset transition_started at dpm_resume_noirq. This patch fixes ACPI warning when resuming from suspend/hibernate: ACPI: \_SB_.PCI0.IDE1.PRI1.MAS1 - docking ------------[ cut here ]------------ WARNING: at drivers/base/power/main.c:87 device_pm_add+0x8b/0xcc() Hardware name: OptiPlex 760 Device: acpi Parentless device registered during a PM transaction [rjw: Fixed up the changelog.] Signed-off-by: Xiaotian Feng <dfeng@redhat.com> Signed-off-by: Rafael J.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | In a number of cases, the .suspend, .freeze, .poweroff and .resume, .thaw, .restore functions are identical. However, they all need to be assigned to avoid regressionsm as the previous code called .suspend resp. .resume in all those cases. SIMPLE_DEV_PM_OPS helps to deal with this case.

| * PM / Hibernate / Memory hotplug: Always use for_each_populated_zone()Gerald Schaefer2009-09-141-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use for_each_populated_zone() instead of for_each_zone() in hibernation code. This fixes a bug on s390, where we allow both config options HIBERNATION and MEMORY_HOTPLUG, so that we also have a ZONE_MOVABLE here. We only allow hibernation if no memory hotplug operation was performed, so in fact both features can only be used exclusively, but this way we don't need 2 differently configured (distribution) kernels. If we have an unpopulated ZONE_MOVABLE, we allow hibernation but run into a BUG_ON() in memory_bm_test/set/clear_bit() because hibernation code iterates through all zones, not only the populated zones, in several places. For example, swsusp_free() does for_each_zone() and then checks for pfn_valid(), which is true even if the zone is not populated, resulting in a BUG_ON() later because the pfn cannot be found in the memory bitmap. Replacing all occurences of for_each_zone() in hibernation code with for_each_populated_zone() would fix this issue.

| * PM/Hibernate: Do not try to allocate too much memory too hard (rev. 2)Rafael J. Wysocki2009-09-141-4/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We want to avoid attempting to free too much memory too hard during hibernation, so estimate the minimum size of the image to use as the lower limit for preallocating memory. The approach here is based on the (experimental) observation that we can't free more page frames than the sum of: * global_page_state(NR_SLAB_RECLAIMABLE) * global_page_state(NR_ACTIVE_ANON) * global_page_state(NR_INACTIVE_ANON) * global_page_state(NR_ACTIVE_FILE) * global_page_state(NR_INACTIVE_FILE) minus * global_page_state(NR_FILE_MAPPED) Namely, if this number is subtracted from the number of saveable pages in the system, we get a good estimate of the minimum reasonable size of a hibernation image.

| * PM/Hibernate: Do not release preallocated memory unnecessarily (rev. 2)Rafael J. Wysocki2009-09-143-72/+147
| | | | | | | | | | | | | | | | | | | | | | | | | | Since the hibernation code is now going to use allocations of memory to make enough room for the image, it can also use the page frames allocated at this stage as image page frames. The low-level hibernation code needs to be rearranged for this purpose, but it allows us to avoid freeing a great number of pages and allocating these same pages once again later, so it generally is worth doing.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Rework swsusp_shrink_memory() so that it calls shrink_all_memory() just once to make some room for the image and then allocates memory to apply more pressure to the memory management subsystem, if necessary. Unfortunately, we don't seem to be able to drop shrink_all_memory() entirely just yet, because that would lead to huge performance regressions in some test cases. Signed-off-by: Rafael J.

With this patch struct pdev_archdata is added to struct platform_device, similar to struct dev_archdata in found in struct device. Useful for architecture code that needs to keep extra data associated with each platform device. Struct pdev_archdata is different from dev.platform_data, the convention is that dev.platform_data points to driver-specific data. It may or may not be required by the driver. The format of this depends on driver but is the same across architectures. The structure pdev_archdata is a place for architecture specific data. This data is handled by architecture specific code (for example runtime PM), and since it is architecture specific it should _never_ be touched by device driver code. Exactly like struct dev_archdata but for platform devices.

But the sed command that converts the '=m' to '=y' still ran. This gives us a distro config with all modules converted to built in! The missing dependency was for conf for localyesconfig.

This patch adds a test to check if .config exists and avoid the moves if it does not. [ Impact: remove warning after make localmodconfig ] Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

This patch changes the order of searching for a config file to consider the .config in the local directory first.

This patch changes streamline_config.pl to search various locations for a config. Here's the list and order of search: /proc/config.gz /boot/vmlinuz-`uname -r` vmlinux # local to the directory /lib/modules/`uname -r`/kernel/kernel/configs.ko kernel/configs.ko kernel/configs.o .config Once it finds a file that contains a config (it checks if the binary objects have configs first) it then uses it to create the .config with minimum modules needed.

This patch adds "__used" to the config.gz data to keep it around so that code like extract-ikconfig can still find it.

Then we can use scripts/extract-ikconfig to find the current modules. This patch changes streamline_config.pl to check if CONFIG_IKCONFIG is not set, and if it is not, it enables it to be a module.

After it creates the .config file, it tests to make sure all the configs that are needed were set. It only looks at the configs that are modules, it does not look at the builtin configs. This causes unnecessary warnings about modules not being covered. Reported-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

If a config that does not have a prompt needs to be set to enable a current module, it will include all configs that select it. Note, streamline_config.pl does not enable modules that are not already enabled. It only keeps enabled those that were enabled and might be needed to compile the current modules. The code to find the selects of a config is after the code that adds the depends. But if a config needed selects but had no dependencies, it would not be set. Because the code would stop before getting to the select. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

This is similar to localmodconfig, but after it removes unnecessary modules it runs sed -i s/=m/=y/ on the .config file. It then runs "make silentoldconfig" to fix any wholes that were created by the conversion of modules to core. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

This patch adds the localmodconfig option. This will automatically run streamline_config.pl on the current .config and then run "make silentoldconfig" to fix any wholes that might have been created. $ make localmodconfig This will remove any module configurations in .config that are not needed to compile the modules that are loaded.
