Since pmc_core_slps0_display() and pmc_core_lpm_display() is responsible for dumping as well as displaying debug registers, there is no need for these two functions to be defined under CONFIG_DEBUG_FS. Hence, relocate these functions from under CONFIG_DEBUG_FS to above the block. Cc: Chen Zhou <chenzhou10@huawei.com> Cc: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Cc: David E.

Just like status registers, Tiger Lake has another set of 6 registers that help with status of the low power mode requirements. They are latched on every PC10 entry/exit and S0ix.y entry/exit as well. Though status and live status registers show the status of same list of requirements, live status registers show the status of the low power mode requirements at the time of reading.

Platforms prior to Tiger Lake has no sub-states of S0ix and accessing device PM states that are latched whenever there is a PC10 entry is possible with the help of slp_s0_debug_status and slp_s0_dbg_latch debugfs entries. If a platform has sub-states of S0ix, no such entries are created. Hence, dump low power status registers on resume When any attempt to enter any low power state was unsuccessful.

If platforms such as Tiger Lake has sub-states of S0ix, then both slp_s0_debug_status and slp_s0_dbg_latch entries become invalid. Thus, remove slp_s0_offset and slp_s0_dbg_maps attributes from tgl_reg_map, so that both the entries are not created.

pmc_core_slps0_dbg_show() is responsible for displaying debug registers through slp_s0_debug_status entry. The driver uses the same but redundant code to dump these debug registers for an S0ix failure. Hence, refactor the driver by removing redundant code and reuse the same function that both dumps registers through slp_s0_debug_status entry and in resume for an S0ix failure. The changes in this patch are preparatory, so platforms that support low power sub-states can dump the debug registers when the attempt to enter low power states are unsuccessful.

Tiger Lake has 6 status registers that are memory mapped. These registers show the status of the low power mode requirements. The registers are latched on every C10 entry or exit and on every s0ix.y entry/exit. Accessing these registers is useful for debugging any low power related activities. Thus, add debugfs entry to access low power mode status registers.

For the command "intel-speed-select perf-profile info": There are two instances of “speed-select-turbo-freq” underneath “perf-profile-level-0” for each package. When we load the output into python with json.load(), the second instance overwrites the first.

Pull new zonefs file system from Damien Le Moal: "Zonefs is a very simple file system exposing each zone of a zoned block device as a file. Unlike a regular file system with native zoned block device support (e.g. f2fs or the on-going btrfs effort), zonefs does not hide the sequential write constraint of zoned block devices to the user. As a result, zonefs is not a POSIX compliant file system. Its goal is to simplify the implementation of zoned block devices support in applications by replacing raw block device file accesses with a richer file based API, avoiding relying on direct block device file ioctls which may be more obscure to developers. One example of this approach is the implementation of LSM (log-structured merge) tree structures (such as used in RocksDB and LevelDB) on zoned block devices by allowing SSTables to be stored in a zone file similarly to a regular file system rather than as a range of sectors of a zoned device. The introduction of the higher level construct "one file is one zone" can help reducing the amount of changes needed in the application while at the same time allowing the use of zoned block devices with various programming languages other than C. Zonefs IO management implementation uses the new iomap generic code. Zonefs has been successfully tested using a functional test suite (available with zonefs userland format tool on github) and a prototype implementation of LevelDB on top of zonefs" * tag 'zonefs-5.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dlemoal/zonefs: zonefs: Add documentation fs: New zonefs file system

Pull x86 fixes from Thomas Gleixner: "A set of fixes for X86: - Ensure that the PIT is set up when the local APIC is disable or configured in legacy mode. This is caused by an ordering issue introduced in the recent changes which skip PIT initialization when the TSC and APIC frequencies are already known. - Handle malformed SRAT tables during early ACPI parsing which caused an infinite loop anda boot hang. - Fix a long standing race in the affinity setting code which affects PCI devices with non-maskable MSI interrupts. The problem is caused by the non-atomic writes of the MSI address (destination APIC id) and data (vector) fields which the device uses to construct the MSI message. The non-atomic writes are mandated by PCI. If both fields change and the device raises an interrupt after writing address and before writing data, then the MSI block constructs a inconsistent message which causes interrupts to be lost and subsequent malfunction of the device. The fix is to redirect the interrupt to the new vector on the current CPU first and then switch it over to the new target CPU. This allows to observe an eventually raised interrupt in the transitional stage (old CPU, new vector) to be observed in the APIC IRR and retriggered on the new target CPU and the new vector. The potential spurious interrupts caused by this are harmless and can in the worst case expose a buggy driver (all handlers have to be able to deal with spurious interrupts as they can and do happen for various reasons). - Add the missing suspend/resume mechanism for the HYPERV hypercall page which prevents resume hibernation on HYPERV guests. This change got lost before the merge window. - Mask the IOAPIC before disabling the local APIC to prevent potentially stale IOAPIC remote IRR bits which cause stale interrupt lines after resume" * tag 'x86-urgent-2020-02-09' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/apic: Mask IOAPIC entries when disabling the local APIC x86/hyperv: Suspend/resume the hypercall page for hibernation x86/apic/msi: Plug non-maskable MSI affinity race x86/boot: Handle malformed SRAT tables during early ACPI parsing x86/timer: Don't skip PIT setup when APIC is disabled or in legacy mode

This is a merge error on my part - the driver was merged into mainline by commit c5951e7c ("Merge tag 'mips_5.6' of git://../mips/linux") over a week ago, but nobody apparently noticed that it didn't actually build due to still having a reference to the devm_ioremap_nocache() function, removed a few days earlier through commit 6a1000bd ("Merge tag 'ioremap-5.6' of git://../ioremap"). Apparently this didn't get any build testing anywhere. Not perhaps all that surprising: it's restricted to 64-bit MIPS only, and only with the new SGI_MFD_IOC3 support enabled. I only noticed because the ioremap conflicts in the ARM SoC driver update made me check there weren't any others hiding, and I found this one. Signed-off-by:
