| 202 | On Intel P6 family processors (Pentium Pro, Pentium II and later) |
| 203 | the Memory Type Range Registers (MTRRs) may be used to control |
| 204 | processor access to memory ranges. This is most useful if you have |
| 205 | a video (VGA) card on a PCI or AGP bus. Enabling write-combining |
| 206 | allows bus write transfers to be combined into a larger transfer |
| 207 | before bursting over the PCI/AGP bus. This can increase performance |
| 208 | of image write operations 2.5 times or more. Saying Y here creates a |
| 209 | /proc/mtrr file which may be used to manipulate your processor's |
| 210 | MTRRs. Typically the X server should use this. |
| 211 | |
| 212 | This code has a reasonably generic interface so that similar |
| 213 | control registers on other processors can be easily supported |
| 214 | as well. |
| 215 | |
| 216 | Saying Y here also fixes a problem with buggy SMP BIOSes which only |
| 217 | set the MTRRs for the boot CPU and not for the secondary CPUs. This |
| 218 | can lead to all sorts of problems, so it's good to say Y here. |
| 219 | |

| 418 | depends on EXPERIMENTAL |
| 419 | help |
| 420 | kexec is a system call that implements the ability to shutdown your |
| 421 | current kernel, and to start another kernel. It is like a reboot |
| 422 | but it is indepedent of the system firmware. And like a reboot |
| 423 | you can start any kernel with it, not just Linux. |
| 424 | |
| 425 | The name comes from the similiarity to the exec system call. |
| 426 | |
| 427 | It is an ongoing process to be certain the hardware in a machine |
| 428 | is properly shutdown, so do not be surprised if this code does not |
| 429 | initially work for you. It may help to enable device hotplugging |
| 430 | support. As of this writing the exact hardware interface is |
| 431 | strongly in flux, so no good recommendation can be made. |

| 443 | help |
| 444 | This gives the physical address where the kernel is loaded. Normally |
| 445 | for regular kernels this value is 0x100000 (1MB). But in the case |
| 446 | of kexec on panic the fail safe kernel needs to run at a different |
| 447 | address than the panic-ed kernel. This option is used to set the load |
| 448 | address for kernels used to capture crash dump on being kexec'ed |
| 449 | after panic. The default value for crash dump kernels is |
| 450 | 0x1000000 (16MB). This can also be set based on the "X" value as |
| 451 | specified in the "crashkernel=YM@XM" command line boot parameter |
| 452 | passed to the panic-ed kernel. Typically this parameter is set as |
| 453 | crashkernel=64M@16M. Please take a look at |
| 454 | Documentation/kdump/kdump.txt for more details about crash dumps. |
| 455 | |
| 456 | Don't change this unless you know what you are doing. |

| 462 | help |
| 463 | This kernel feature is useful for number crunching applications |
| 464 | that may need to compute untrusted bytecode during their |
| 465 | execution. By using pipes or other transports made available to |
| 466 | the process as file descriptors supporting the read/write |
| 467 | syscalls, it's possible to isolate those applications in |
| 468 | their own address space using seccomp. Once seccomp is |
| 469 | enabled via /proc/<pid>/seccomp, it cannot be disabled |
| 470 | and the task is only allowed to execute a few safe syscalls |
| 471 | defined by each seccomp mode. |
| 472 | |
| 473 | If unsure, say Y. Only embedded should say N here. |
