The default value is 0 no limit. On kernel version 2. Sometimes CPU hardware bugs make them report the cache size incorrectly. The most common failure mode is ‘black screen on resuming’, but the system may also hang while suspending. Add missing “space” [MIPS] vpe: To post a comment you must log in.

This is used to specify the TCP metrics cache size. M68k M68k architecture is enabled.
Common kernel problems
Increasing these values may allow you to improve throughput, but will also increase the amount of memory reserved for use by the client. By default, this is disabled due to x86 early mapping size limitation. This tests the locking primitive’s ability to transition abruptly to and from idle. This usage is only documented in each driver source file if at all. TJ tj wrote on If the system runs very slowly, it may have a BIOS bug that causes part of the system memory to be uncached.

Common kernel problems – Fedora Project Wiki
Can override in debugfs after boot. Turn on or off NCQ. The opposite of ioapicreroute. Fix NAPI regression with reset work mac Changing the reboot ljbata can work around this problem.
Fix userspace corruption on bit. We have interrupts disabled while waiting for the ACK, so if this is set too high interrupts may be lost!
This option can be used to adsign the best performance for a particular HW. Also note the kernel might malfunction if you disable some critical bits. Fix early use of port printk. This command is useful when one do not care about the state of the feature group strings which should be controlled by the OSPM.
Defaults to the default architecture’s huge page size if not specified. Fix deleting key operation. When enabled, memory and cache locality will be impacted.
The default is to send the implementation identification information. The touchscreen support is not enabled in the mainstream kernel as of 2.
Linux Kernel Parameters
May be overridden by other higher priority error reporting module. Default value is 0. If both kernelcore and movablecore is specified, then kernelcore will be at least the specified value but may be more. Drivers that are needed to boot the system are put into an initrd, and their options are copied from modprobe.
Use this parameter to check at some other rate. The sclp output can only be used on s I haven’t found a workaround. N, where N is the number of CPUs rcuperf.
