module: Convert symbol namespace to string literal

2024-12-02T19:34:44Z

Clean up the existing export namespace code along the same lines of commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo) to __section("foo")") and for the same reason, it is not desired for the namespace argument to be a macro expansion itself.

platform/x86/intel/pmc: Disable C1 auto-demotion during suspend

2024-10-22T08:50:58Z

On some platforms, aggressive C1 auto-demotion may lead to failure to enter the deepest C-state during suspend-to-idle, causing high power consumption. To prevent this, disable C1 auto-demotion during suspend and re-enable on resume. Signed-off-by: David E. Box Reviewed-by: Rafael J.

platform/x86:intel/pmc: Revert "Enable the ACPI PM Timer to be turned off when suspended"

Commit e86c8186d03a ("platform/x86:intel/pmc: Enable the ACPI PM Timer to be turned off when suspended") can cause the suspend process to hang as the pmcdev->lock in the pmc_core_acpi_pm_timer_suspend_resume might already be held by the pmc_core_mphy_pg_show or pmc_core_pll_show if the userspace gets frozen when these functions are being executed. Also, pmc_core_acpi_pm_timer_suspend_resume must not sleep, as this function is called indirectly by the tick_freeze function in kernel/time/tick-common.c, which holds the spinlock.

platform/x86: Switch back to struct platform_driver::remove()

2024-10-17T09:39:32Z

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/platform/x86/ to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer. While touching these files, make indention of the struct initializer consistent in several files.

platform/x86: intel/pmc: Ignore all LTRs during suspend

2024-09-11T12:11:14Z

Add support to ignore all LTRs before suspend and restore the previous LTR values after suspend. This feature could be turned off with module parameter ltr_ignore_all_suspend. LTR value is a mechanism for a device to indicate tolerance to access the corresponding resource. When system suspends, the resource is not available and therefore the LTR value could be ignored. Ignoring all LTR values prevents problematic device from blocking the system to get to the deepest package state during suspend. Suggested-by: Rafael J.
