+Description:
+
+ As a Kconfig option, individual GPIO signals may be accessed from
+ userspace. GPIOs are only made available to userspace by an explicit
+ "export" operation. If a given GPIO is not claimed for use by
+ kernel code, it may be exported by userspace (and unexported later).
+ Kernel code may export it for complete or partial access.
+
+ GPIOs are identified as they are inside the kernel, using integers in
+ the range 0..INT_MAX. See Documentation/gpio.txt for more information.
+
+ /sys/class/gpio
+ /export ... asks the kernel to export a GPIO to userspace
+ /unexport ... to return a GPIO to the kernel
+ /gpioN ... for each exported GPIO #N
+ /value ... always readable, writes fail for input GPIOs
+ /direction ... r/w as: in, out (default low); write: high, low
+ /gpiochipN ... for each gpiochip; #N is its first GPIO
+ /base ... (r/o) same as N
+ /label ... (r/o) descriptive, not necessarily unique
+ /ngpio ... (r/o) number of GPIOs; numbered N to N + (ngpio - 1)

- SMTC pseudo-interrupts between TCs are deferred and queued
- if the target TC is interrupt-inhibited (IXMT). In the first
- SMTC prototypes, these queued IPIs were serviced on return
- to user mode, or on entry into the kernel idle loop. The
- INSTANT_REPLAY option dispatches them as part of local_irq_restore()
- processing, which adds runtime overhead (hence the option to turn
- it off), but ensures that IPIs are handled promptly even under
- heavy I/O interrupt load.

help
To support multiple TC microthreads acting as "CPUs" within
a VPE, VPE-wide interrupt mask bits must be specially manipulated
during interrupt handling. To support legacy drivers and interrupt
controller management code, SMTC has a "backstop" to track and
if necessary restore the interrupt mask. This has some performance
- impact on interrupt service overhead. Disable it only if you know
- what you are doing.

+ * Variant clock event timer support for SMTC on MIPS 34K, 1004K
+ * or other MIPS MT cores.
+ *
+ * Notes on SMTC Support:
+ *
+ * SMTC has multiple microthread TCs pretending to be Linux CPUs.
+ * But there's only one Count/Compare pair per VPE, and Compare
+ * interrupts are taken opportunisitically by available TCs
+ * bound to the VPE with the Count register. The new timer
+ * framework provides for global broadcasts, but we really
+ * want VPE-level multicasts for best behavior. So instead
+ * of invoking the high-level clock-event broadcast code,
+ * this version of SMTC support uses the historical SMTC
+ * multicast mechanisms "under the hood", appearing to the
+ * generic clock layer as if the interrupts are per-CPU.
+ *
+ * The approach taken here is to maintain a set of NR_CPUS
+ * virtual timers, and track which "CPU" needs to be alerted
+ * at each event.
+ *
+ * It's unlikely that we'll see a MIPS MT core with more than
+ * 2 VPEs, but we *know* that we won't need to handle more
+ * VPEs than we have "CPUs". So NCPUs arrays of NCPUs elements
+ * is always going to be overkill, but always going to be enough.

tristate "generic/default IDE chipset support"
depends on ALPHA || X86 || IA64 || M32R || MIPS
help
+ This is the generic IDE driver. This driver attaches to the
+ fixed legacy ports (e.g. on PCs 0x1f0/0x170, 0x1e8/0x168 and
+ so on). Please note that if this driver is built into the
+ kernel or loaded before other ATA (IDE or libata) drivers
+ and the controller is located at legacy ports, this driver
+ may grab those ports and thus can prevent the controller
+ specific driver from attaching.
+
+ Also, currently, IDE generic doesn't allow IRQ sharing
+ meaning that the IRQs it grabs won't be available to other
+ controllers sharing those IRQs which usually makes drivers
+ for those controllers fail. Generally, it's not a good idea
+ to load IDE generic driver on modern systems.
+
If unsure, say N.
