79 bool "Set upper limit of TLB entries to flush one-by-one"
83 X86-only for now.
86 kernel flushes one-by-one instead of doing a full TLB flush. In
89 to -1, the code flushes the whole TLB unconditionally. Otherwise,
107 code. When you use it make sure you have a big enough
110 options. See Documentation/x86/x86_64/boot-options.rst for more
138 bool "port 0x80 based port-IO delay [recommended]"
144 bool "port 0xed based port-IO delay"
147 often used as a hardware-debug port.
150 bool "udelay based port-IO delay"
153 while not having any side-effect on the IO port space.
156 bool "no port-IO delay"
158 No port-IO delay. Will break on old boxes that require port-IO
171 bool "CPA self-test code"
174 Do change_page_attr() self-tests every 30 seconds.
177 bool "Debug low-level entry code"
180 This option enables sanity checks in x86's low-level entry code.
250 a simplified version of the DWARF Call Frame Information standard.
253 frame pointer unwinder. It also enables a 5-10% performance
254 improvement across the entire kernel compared to frame pointers.
257 by roughly 2-4MB, depending on your kernel config.
260 bool "Frame pointer unwinder"
263 This option enables the frame pointer unwinder for unwinding kernel
268 overall performance will degrade by roughly 5-10%.
280 useful in many cases. Unlike the other unwinders, it has no runtime
