-3) Supporting multiple types of IOMMUs
-
- If your architecture needs to support multiple types of IOMMUs, you
- can use include/linux/asm-generic/dma-mapping-common.h. It's a
- library to support the DMA API with multiple types of IOMMUs. Lots
- of architectures (x86, powerpc, sh, alpha, ia64, microblaze and
- sparc) use it. Choose one to see how it can be used. If you need to
- support multiple types of IOMMUs in a single system, the example of
- x86 or powerpc helps.

system than killing the group. Otherwise, memory.max is there to
limit this type of spillover and ultimately contain buggy or even

+
+The combined memory+swap accounting and limiting is replaced by real

+
+The main argument for a combined memory+swap facility in the original
+cgroup design was that global or parental pressure would always be
+able to swap all anonymous memory of a child group, regardless of the
+child's own (possibly untrusted) configuration. However, untrusted
+groups can sabotage swapping by other means - such as referencing its
+anonymous memory in a tight loop - and an admin can not assume full
+swappability when overcommitting untrusted jobs.
+
+For trusted jobs, on the other hand, a combined counter is not an
+intuitive userspace interface, and it flies in the face of the idea
+that cgroup controllers should account and limit specific physical
+resources. Swap space is a resource like all others in the system,
+and that's why unified hierarchy allows distributing it separately.

+Broadcom Northstar Plus SoC CPU Enable Method

+This binding defines the enable method used for starting secondary
+CPU in the following Broadcom SoCs:
+ BCM58522, BCM58525, BCM58535, BCM58622, BCM58623, BCM58625, BCM88312
+
+The enable method is specified by defining the following required
+properties in the corresponding secondary "cpu" device tree node:
+ - enable-method = "brcm,bcm-nsp-smp";
+ - secondary-boot-reg = <...>;
+
+The secondary-boot-reg property is a u32 value that specifies the
+physical address of the register which should hold the common
+entry point for a secondary CPU. This entry is cpu node specific
+and should be added per cpu. E.g., in case of NSP (BCM58625) which
+is a dual core CPU SoC, this entry should be added to cpu1 node.
+
+
+Example:
+ cpus {
+ #address-cells = <1>;
+ #size-cells = <0>;

+ cpu0: cpu@0 {
+ device_type = "cpu";

+UniPhier System Bus
+
+The UniPhier System Bus is an external bus that connects on-board devices to
+the UniPhier SoC. It is a simple (semi-)parallel bus with address, data, and
+some control signals. It supports up to 8 banks (chip selects).
+
+Before any access to the bus, the bus controller must be configured; the bus
+controller registers provide the control for the translation from the offset
+within each bank to the CPU-viewed address. The needed setup includes the base
+address, the size of each bank. Optionally, some timing parameters can be
+optimized for faster bus access.
+
+Required properties:
+- compatible: should be "socionext,uniphier-system-bus".
+- reg: offset and length of the register set for the bus controller device.
+- #address-cells: should be 2. The first cell is the bank number (chip select).
+ The second cell is the address offset within the bank.
+- #size-cells: should be 1.
+- ranges: should provide a proper address translation from the System Bus to
+ the parent bus.
+
+Note:
+The address region(s) that can be assigned for the System Bus is implementation
+defined. Some SoCs can use 0x00000000-0x0fffffff and 0x40000000-0x4fffffff,
+while other SoCs can only use 0x40000000-0x4fffffff. There might be additional
+limitations depending on SoCs and the boot mode. The address translation is
+arbitrary as long as the banks are assigned in the supported address space with
+the required alignment and they do not overlap one another.
+For example, it is possible to map:
+ bank 0 to 0x42000000-0x43ffffff, bank 5 to 0x46000000-0x46ffffff
+It is also possible to map:
+ bank 0 to 0x48000000-0x49ffffff, bank 5 to 0x44000000-0x44ffffff
+There is no reason to stick to a particular translation mapping, but the
+"ranges" property should provide a "reasonable" default that is known to work.
+The software should initialize the bus controller according to it.
+
+Example:
+
+ system-bus {
+ compatible = "socionext,uniphier-system-bus";
+ reg = <0x58c00000 0x400>;
+ #address-cells = <2>;
+ #size-cells = <1>;
+ ranges = <1 0x00000000 0x42000000 0x02000000
+ 5 0x00000000 0x46000000 0x01000000>;
+
+ ethernet@1,01f00000 {
+ compatible = "smsc,lan9115";
+ reg = <1 0x01f00000 0x1000>;
+ interrupts = <0 48 4>
+ phy-mode = "mii";
+ };
+
+ uart@5,00200000 {
+ compatible = "ns16550a";
+ reg = <5 0x00200000 0x20>;
+ interrupts = <0 49 4>
+ clock-frequency = <12288000>;
+ };
+ };
+
+In this example,
+ - the Ethernet device is connected at the offset 0x01f00000 of CS1 and
+ mapped to 0x43f00000 of the parent bus.
+ - the UART device is connected at the offset 0x00200000 of CS5 and
+ mapped to 0x46200000 of the parent bus.

+ARM System Controller ICST clocks
+
+The ICS525 and ICS307 oscillators are produced by Integrated Devices
+Technology (IDT). ARM integrated these oscillators deeply into their
+reference designs by adding special control registers that manage such
+oscillators to their system controllers.
+
+The ARM system controller contains logic to serialize and initialize
+an ICST clock request after a write to the 32 bit register at an offset
+into the system controller. Furthermore, to even be able to alter one of
+these frequencies, the system controller must first be unlocked by
+writing a special token to another offset in the system controller.
+
+The ICST oscillator must be provided inside a system controller node.
+
+Required properties:
+- lock-offset: the offset address into the system controller where the
+ unlocking register is located
+- vco-offset: the offset address into the system controller where the
+ ICST control register is located (even 32 bit address)
+- compatible: must be one of "arm,syscon-icst525" or "arm,syscon-icst307"
+- #clock-cells: must be <0>
+- clocks: parent clock, since the ICST needs a parent clock to derive its
+ frequency from, this attribute is compulsory.
+
+Example:
+
+syscon: syscon@10000000 {
+ compatible = "syscon";
+ reg = <0x10000000 0x1000>;

+Microchip PIC32 Interrupt Controller
+====================================
+
+The Microchip PIC32 contains an Enhanced Vectored Interrupt Controller (EVIC).
+It handles all internal and external interrupts. This controller exists outside
+of the CPU and is the arbitrator of all interrupts (including interrupts from
+the CPU itself) before they are presented to the CPU.
+
+External interrupts have a software configurable edge polarity. Non external
+interrupts have a type and polarity that is determined by the source of the
+interrupt.
+
+Required properties
+-------------------
+
+- compatible: Should be "microchip,pic32mzda-evic"
+- reg: Specifies physical base address and size of register range.
+- interrupt-controller: Identifies the node as an interrupt controller.
+- #interrupt cells: Specifies the number of cells used to encode an interrupt
+ source connected to this controller. The value shall be 2 and interrupt
+ descriptor shall have the following format:
+
+ <hw_irq irq_type>
+
+ hw_irq - represents the hardware interrupt number as in the data sheet.
+ irq_type - is used to describe the type and polarity of an interrupt. For
+ internal interrupts use IRQ_TYPE_EDGE_RISING for non persistent interrupts and
+ IRQ_TYPE_LEVEL_HIGH for persistent interrupts. For external interrupts use
+ IRQ_TYPE_EDGE_RISING or IRQ_TYPE_EDGE_FALLING to select the desired polarity.
+
+Optional properties
+-------------------
+- microchip,external-irqs: u32 array of external interrupts with software
+ polarity configuration. This array corresponds to the bits in the INTCON
+ SFR.
+
+Example
+-------
+
+evic: interrupt-controller@1f810000 {
+ compatible = "microchip,pic32mzda-evic";
+ interrupt-controller;
+ #interrupt-cells = <2>;
+ reg = <0x1f810000 0x1000>;
+ microchip,external-irqs = <3 8 13 18 23>;
+};
+
+Each device/peripheral must request its interrupt line with the associated type
+and polarity.
+
+Internal interrupt DTS snippet
+------------------------------
+
+device@1f800000 {
+ ...
+ interrupts = <113 IRQ_TYPE_LEVEL_HIGH>;
+ ...
+};

+Wakeup M3 IPC Driver
+=====================
+
+The TI AM33xx and AM43xx family of devices use a small Cortex M3 co-processor
+(commonly referred to as Wakeup M3 or CM3) to help with various low power tasks
+that cannot be controlled from the MPU, like suspend/resume and certain deep
+C-states for CPU Idle. Once the wkup_m3_ipc driver uses the wkup_m3_rproc driver
+to boot the wkup_m3, it handles communication with the CM3 using IPC registers
+present in the SoC's control module and a mailbox. The wkup_m3_ipc exposes an
+API to allow the SoC PM code to execute specific PM tasks.
+
+Wkup M3 Device Node:
+====================
+A wkup_m3_ipc device node is used to represent the IPC registers within an
+SoC.
+
+Required properties:
+--------------------
+- compatible: Should be,
+ "ti,am3352-wkup-m3-ipc" for AM33xx SoCs
+ "ti,am4372-wkup-m3-ipc" for AM43xx SoCs
+- reg: Contains the IPC register address space to communicate
+ with the Wakeup M3 processor
+- interrupts: Contains the interrupt information for the wkup_m3
+ interrupt that signals the MPU.
+- ti,rproc: phandle to the wkup_m3 rproc node so the IPC driver
+ can boot it.
+- mboxes: phandles used by IPC framework to get correct mbox
+ channel for communication. Must point to appropriate
+ mbox_wkupm3 child node.
+
+Example:
+--------
+/* AM33xx */
+ l4_wkup: l4_wkup@44c00000 {
+ ...
+
+ scm: scm@210000 {

+Undefined Behavior Sanitizer - UBSAN
+
+Overview
+--------
+
+UBSAN is a runtime undefined behaviour checker.
+
+UBSAN uses compile-time instrumentation to catch undefined behavior (UB).
+Compiler inserts code that perform certain kinds of checks before operations
+that may cause UB. If check fails (i.e. UB detected) __ubsan_handle_*
+function called to print error message.
+
+GCC has that feature since 4.9.x [1] (see -fsanitize=undefined option and
+its suboptions). GCC 5.x has more checkers implemented [2].
+
+Report example

+
+Usage
+-----
+
+To enable UBSAN configure kernel with:
+
+ CONFIG_UBSAN=y
+
+and to check the entire kernel:
+
+ CONFIG_UBSAN_SANITIZE_ALL=y
+
+To enable instrumentation for specific files or directories, add a line
+similar to the following to the respective kernel Makefile:
+
+ For a single file (e.g. main.o):
+ UBSAN_SANITIZE_main.o := y
+
+ For all files in one directory:
+ UBSAN_SANITIZE := y
+
+To exclude files from being instrumented even if
+CONFIG_UBSAN_SANITIZE_ALL=y, use:
+
+ UBSAN_SANITIZE_main.o := n
+ and:
+ UBSAN_SANITIZE := n
+
+Detection of unaligned accesses controlled through the separate option -
+CONFIG_UBSAN_ALIGNMENT. It's off by default on architectures that support
+unaligned accesses (CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS=y). One could
+still enable it in config, just note that it will produce a lot of UBSAN
+reports.

+ and devices attached to them, to be removed from the default
+ PCI domain and placed within the VMD domain. This provides
+ more bus resources than are otherwise possible with a
+ single domain. If you know your system provides one of these and
+ has devices attached to it, say Y; if you are not sure, say N.

+ * - End of DMA (cleared by ending DMA Mode)
+ * - Parity error (cleared by reading RPIR)
+ * - Loss of BSY (cleared by reading RPIR)
+ * Two conditions have flag bits that are not latched:
+ * - Bus phase mismatch (non-maskable in DMA Mode, cleared by ending DMA Mode)
+ * - Bus reset (non-maskable)
+ * The remaining condition has no flag bit at all:
+ * - Selection/reselection
+ *
+ * Hence, establishing the cause(s) of any interrupt is partly guesswork.

+ * The L5380/53C80 datasheet from LOGIC Devices has more details.
+ *
+ * Checking for bus reset by reading RST is futile because of interrupt
+ * latency, but a bus reset will reset chip logic. Checking for parity error
+ * is unnecessary because that interrupt is never enabled. A Loss of BSY
+ * condition will clear DMA Mode. We can tell when this occurs because the

- * ++roman: To port the 5380 driver to the Atari, I had to do some changes in
- * this file, too:
- *
- * - Some of the debug statements were incorrect (undefined variables and the
- * like). I fixed that.
- *
- * - In information_transfer(), I think a #ifdef was wrong. Looking at the
- * possible DMA transfer size should also happen for REAL_DMA. I added this
- * in the #if statement.
- *
- * - When using real DMA, information_transfer() should return in a DATAOUT
- * phase after starting the DMA. It has nothing more to do.
- *
- * - The interrupt service routine should run main after end of DMA, too (not
- * only after RESELECTION interrupts). Additionally, it should _not_ test
- * for more interrupts after running main, since a DMA process may have
- * been started and interrupts are turned on now. The new int could happen
- * inside the execution of NCR5380_intr(), leading to recursive
- * calls.
- *
- * - I've added a function merge_contiguous_buffers() that tries to
- * merge scatter-gather buffers that are located at contiguous
- * physical addresses and can be processed with the same DMA setup.
- * Since most scatter-gather operations work on a page (4K) of
- * 4 buffers (1K), in more than 90% of all cases three interrupts and
- * DMA setup actions are saved.
- *
- * - I've deleted all the stuff for AUTOPROBE_IRQ, REAL_DMA_POLL, PSEUDO_DMA
- * and USLEEP, because these were messing up readability and will never be
- * needed for Atari SCSI.
- *
- * - I've revised the NCR5380_main() calling scheme (relax the 'main_running'
- * stuff), and 'main' is executed in a bottom half if awoken by an
- * interrupt.
- *
- * - The code was quite cluttered up by "#if (NDEBUG & NDEBUG_*) printk..."
- * constructs. In my eyes, this made the source rather unreadable, so I
- * finally replaced that by the *_PRINTK() macros.

+ * This driver implements the Qualcomm Shared Memory State Machine, a mechanism

+ *
+ * The implementation is based on two sections of shared memory; the first

+ *
+ * The state bits are structured in entries of 32 bits, each belonging to one
+ * system in the SoC. The entry belonging to the local system is considered
+ * read-write, while the rest should be considered read-only.
+ *
+ * The subscription matrix consists of N bitmaps per entry, denoting interest
+ * in updates of the entry for each of the N hosts. Upon updating a state bit
+ * each host's subscription bitmap should be queried and the remote system
+ * should be interrupted if they request so.
+ *
+ * The subscription matrix is laid out in entry-major order:
+ * entry0: [host0 ... hostN]
+ * .
+ * .
+ * entryM: [host0 ... hostN]
+ *
+ * A third, optional, shared memory region might contain information regarding
+ * the number of entries in the state bitmap as well as number of columns in
