+.Os Hyra
+.Sh NAME
+.Nm kconf - Hyra kernel configuration
+.Sh SYNOPSIS
+GENERIC configuration:
+.Ft sys/arch/<arch>/conf/GENERIC
+
+Kconf sources:
+.Ft tools/kconf/
+
+.Sh DESCRIPTION
+
+Hyra provides the kconf format for kernel configuration by allowing
+the user to create defines that represent yes/no options and fixed values.
+
+Running kconf on a configuration file results in define flags (-D__KEY=val) to
+be generated so that they may be passed to the compiler of choice.
+
+The
+.Ft option
+keyword allows users to define an option that
+can either be yes or no. For example, the following
+may be used to create an option "FOO" to be set to "yes":
+
+.Ft option FOO yes
+
+This will be given to the kernel as __FOO, for yes/no options the value
+of either 1 (yes) or 0 will be given.
+
+Similarly, a user may create a define that holds a fixed value
+by using the
+.Ft setval
+keyword.
+
+For example, the following may be used to create an option
+"MEOW" set to 0xCA7F00D:
+
+.Ft setval MEOW 0xCA7F00D
+
+These options can be read within the kernel by checking if
+the define exists and potentially falling back to a default
+value if not. This example shows how "MEOW" can be read:
+
+.Bd -literal
+#if defined(__MEOW)     /* Option is prefixed with "__" */
+#define MEOW __MEOW
+#else
+#define MEOW 0
+#endif  /* __MEOW */

+.Sh NAME
+.Nm mmio - hyra MMIO interface
+.Sh SYNOPSIS
+.In sys/mmio.h
+
+.Bd -literal
+static inline void mmio_write8(void *addr, uint8_t val);
+static inline void mmio_write16(void *addr, uint16_t val);
+static inline void mmio_write32(void *addr, uint32_t val);

+static inline void mmio_write64(void *addr, uint64_t val);
+#endif
+__extension__
+.Ed
+
+.Sh DESCRIPTION
+In short, MMIO is a method of writing to registers
+of an I/O device via a mapped porition of memory. MMIO
+should NOT be done on your own when doing Hyra kernel programming.
+Instead, rely on Hyra's MMIO interface and use
+.Ft mmio_read<n>()
+and
+.Ft mmio_write<n>()
+functions. Where `n` is 8 to 32 on 32-bit machines, and to 64
+on 64-bit machines.
+
+The
+.Ft addr
+argument can be either a physical address or virtual
+address; however, it is recommended to use virtual addresses
+for the sake of consistency.

+
+.Ft void

+
+.Sh DESCRIPTION
+The PCI configuration space is a 256-byte region implemented
+per device, consisting of registers used for host-to-device
+communication and device-specific configuration.
+
+The Hyra PCI driver provides an API for interfacing
+with a device's configuration space.
+
+The
+.Ft pci_readl()
+function returns a 32-bit value from the
+configuration space of the device pointed
+to by the
+.Ft dev
+argument. The
+.Ft offset
+argument describes how far into the configuration
+space should be read from.
+
+The
+.Ft pci_writel()
+function writes a 32-bit value into the configuration
+space of the device pointed to by the
+.Ft dev
+argument. The
+.Ft offset
+argument describes how far into the configuration space
+.Ft val
+should be written to.
+
+For more information, refer to section 6 of the PCI Local Bus
+Specification 3.0
