See next chapter.
- Chapter 5: Functions
+ Chapter 5: Typedefs
+
+Please don't use things like "vps_t".
+
+It's a _mistake_ to use typedef for structures and pointers. When you see a
+
+ vps_t a;
+
+in the source, what does it mean?
+
+In contrast, if it says
+
+ struct virtual_container *a;
+
+you can actually tell what "a" is.
+
+Lots of people think that typedefs "help readability". Not so. They are
+useful only for:
+
+ (a) totally opaque objects (where the typedef is actively used to _hide_
+ what the object is).
+
+ Example: "pte_t" etc. opaque objects that you can only access using
+ the proper accessor functions.
+
+ NOTE! Opaqueness and "accessor functions" are not good in themselves.
+ The reason we have them for things like pte_t etc. is that there
+ really is absolutely _zero_ portably accessible information there.
+
+ (b) Clear integer types, where the abstraction _helps_ avoid confusion
+ whether it is "int" or "long".
+
+ u8/u16/u32 are perfectly fine typedefs, although they fit into
+ category (d) better than here.
+
+ NOTE! Again - there needs to be a _reason_ for this. If something is
+ "unsigned long", then there's no reason to do
+
+ typedef unsigned long myflags_t;
+
+ but if there is a clear reason for why it under certain circumstances
+ might be an "unsigned int" and under other configurations might be
+ "unsigned long", then by all means go ahead and use a typedef.
+
+ (c) when you use sparse to literally create a _new_ type for
+ type-checking.
+
+ (d) New types which are identical to standard C99 types, in certain
+ exceptional circumstances.
+
+ Although it would only take a short amount of time for the eyes and
+ brain to become accustomed to the standard types like 'uint32_t',
+ some people object to their use anyway.
+
+ Therefore, the Linux-specific 'u8/u16/u32/u64' types and their
+ signed equivalents which are identical to standard types are
+ permitted -- although they are not mandatory in new code of your
+ own.
+
+ When editing existing code which already uses one or the other set
+ of types, you should conform to the existing choices in that code.
+
+ (e) Types safe for use in userspace.
+
+ In certain structures which are visible to userspace, we cannot
+ require C99 types and cannot use the 'u32' form above. Thus, we
+ use __u32 and similar types in all structures which are shared
+ with userspace.
+
+Maybe there are other cases too, but the rule should basically be to NEVER
+EVER use a typedef unless you can clearly match one of those rules.
+
+In general, a pointer, or a struct that has elements that can reasonably
+be directly accessed should _never_ be a typedef.

+Linux Kernel patch sumbittal checklist
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Here are some basic things that developers should do if they
+want to see their kernel patch submittals accepted quicker.
+
+These are all above and beyond the documentation that is provided
+in Documentation/SubmittingPatches and elsewhere about submitting
+Linux kernel patches.
+
+
+
+- Builds cleanly with applicable or modified CONFIG options =y, =m, and =n.
+ No gcc warnings/errors, no linker warnings/errors.
+
+- Passes allnoconfig, allmodconfig
+
+- Builds on multiple CPU arch-es by using local cross-compile tools
+ or something like PLM at OSDL.
+
+- ppc64 is a good architecture for cross-compilation checking because it
+ tends to use `unsigned long' for 64-bit quantities.
+
+- Matches kernel coding style(!)
+
+- Any new or modified CONFIG options don't muck up the config menu.
+
+- All new Kconfig options have help text.
+
+- Has been carefully reviewed with respect to relevant Kconfig
+ combinations. This is very hard to get right with testing --
+ brainpower pays off here.
+
+- Check cleanly with sparse.
+
+- Use 'make checkstack' and 'make namespacecheck' and fix any
+ problems that they find. Note: checkstack does not point out
+ problems explicitly, but any one function that uses more than
+ 512 bytes on the stack is a candidate for change.
+
+- Include kernel-doc to document global kernel APIs. (Not required
+ for static functions, but OK there also.) Use 'make htmldocs'
+ or 'make mandocs' to check the kernel-doc and fix any issues.
+
+- Has been tested with CONFIG_PREEMPT, CONFIG_DEBUG_PREEMPT,
+ CONFIG_DEBUG_SLAB, CONFIG_DEBUG_PAGEALLOC, CONFIG_DEBUG_MUTEXES,
+ CONFIG_DEBUG_SPINLOCK, CONFIG_DEBUG_SPINLOCK_SLEEP all simultaneously
+ enabled.
+
+- Has been build- and runtime tested with and without CONFIG_SMP and
+ CONFIG_PREEMPT.
+
+- If the patch affects IO/Disk, etc: has been tested with and without
+ CONFIG_LBD.

-Files: include/linux/rcupdate.h, kernel/rcupdate.c
-Why: Outside of Linux, the only implementations of anything even

- VM/XA, Tornado, and K42. I do not expect anyone to port binary

+ MEMORY ATTRIBUTE ALIASING ON IA-64
+
+ Bjorn Helgaas

+
+
+MEMORY ATTRIBUTES
+
+ Itanium supports several attributes for virtual memory references.
+ The attribute is part of the virtual translation, i.e., it is
+ contained in the TLB entry. The ones of most interest to the Linux
+ kernel are:
+
+ WB Write-back (cacheable)
+ UC Uncacheable
+ WC Write-coalescing
+
+ System memory typically uses the WB attribute. The UC attribute is
+ used for memory-mapped I/O devices. The WC attribute is uncacheable
+ like UC is, but writes may be delayed and combined to increase
+ performance for things like frame buffers.
+
+ The Itanium architecture requires that we avoid accessing the same
+ page with both a cacheable mapping and an uncacheable mapping[1].
+
+ The design of the chipset determines which attributes are supported
+ on which regions of the address space. For example, some chipsets
+ support either WB or UC access to main memory, while others support
+ only WB access.
+
+MEMORY MAP
+
+ Platform firmware describes the physical memory map and the
+ supported attributes for each region. At boot-time, the kernel uses
+ the EFI GetMemoryMap() interface. ACPI can also describe memory
+ devices and the attributes they support, but Linux/ia64 currently
+ doesn't use this information.
+
+ The kernel uses the efi_memmap table returned from GetMemoryMap() to
+ learn the attributes supported by each region of physical address
+ space. Unfortunately, this table does not completely describe the
+ address space because some machines omit some or all of the MMIO
+ regions from the map.
+
+ The kernel maintains another table, kern_memmap, which describes the
+ memory Linux is actually using and the attribute for each region.
+ This contains only system memory; it does not contain MMIO space.
+
+ The kern_memmap table typically contains only a subset of the system
+ memory described by the efi_memmap. Linux/ia64 can't use all memory
+ in the system because of constraints imposed by the identity mapping
+ scheme.
+
+ The efi_memmap table is preserved unmodified because the original
+ boot-time information is required for kexec.
+
+KERNEL IDENTITY MAPPINGS
+
+ Linux/ia64 identity mappings are done with large pages, currently
+ either 16MB or 64MB, referred to as "granules." Cacheable mappings
+ are speculative[2], so the processor can read any location in the
+ page at any time, independent of the programmer's intentions. This
+ means that to avoid attribute aliasing, Linux can create a cacheable
+ identity mapping only when the entire granule supports cacheable
+ access.
+
+ Therefore, kern_memmap contains only full granule-sized regions that
+ can referenced safely by an identity mapping.
+
+ Uncacheable mappings are not speculative, so the processor will
+ generate UC accesses only to locations explicitly referenced by
+ software. This allows UC identity mappings to cover granules that
+ are only partially populated, or populated with a combination of UC
+ and WB regions.
+
+USER MAPPINGS
+
+ User mappings are typically done with 16K or 64K pages. The smaller
+ page size allows more flexibility because only 16K or 64K has to be
+ homogeneous with respect to memory attributes.
+
+POTENTIAL ATTRIBUTE ALIASING CASES
+
+ There are several ways the kernel creates new mappings:
+
+ mmap of /dev/mem
+
+ This uses remap_pfn_range(), which creates user mappings. These
+ mappings may be either WB or UC. If the region being mapped
+ happens to be in kern_memmap, meaning that it may also be mapped
+ by a kernel identity mapping, the user mapping must use the same
+ attribute as the kernel mapping.
+
+ If the region is not in kern_memmap, the user mapping should use
+ an attribute reported as being supported in the EFI memory map.
+
+ Since the EFI memory map does not describe MMIO on some
+ machines, this should use an uncacheable mapping as a fallback.
+
+ mmap of /sys/class/pci_bus/.../legacy_mem
+
+ This is very similar to mmap of /dev/mem, except that legacy_mem
+ only allows mmap of the one megabyte "legacy MMIO" area for a
+ specific PCI bus. Typically this is the first megabyte of
+ physical address space, but it may be different on machines with
+ several VGA devices.
+
+ "X" uses this to access VGA frame buffers. Using legacy_mem
+ rather than /dev/mem allows multiple instances of X to talk to
+ different VGA cards.
+
+ The /dev/mem mmap constraints apply.
+
+ However, since this is for mapping legacy MMIO space, WB access
+ does not make sense. This matters on machines without legacy
+ VGA support: these machines may have WB memory for the entire
+ first megabyte (or even the entire first granule).
+
+ On these machines, we could mmap legacy_mem as WB, which would
+ be safe in terms of attribute aliasing, but X has no way of
+ knowing that it is accessing regular memory, not a frame buffer,
+ so the kernel should fail the mmap rather than doing it with WB.
+
+ read/write of /dev/mem
+
+ This uses copy_from_user(), which implicitly uses a kernel
+ identity mapping. This is obviously safe for things in
+ kern_memmap.
+
+ There may be corner cases of things that are not in kern_memmap,
+ but could be accessed this way. For example, registers in MMIO
+ space are not in kern_memmap, but could be accessed with a UC
+ mapping. This would not cause attribute aliasing. But
+ registers typically can be accessed only with four-byte or
+ eight-byte accesses, and the copy_from_user() path doesn't allow
+ any control over the access size, so this would be dangerous.
+
+ ioremap()
+
+ This returns a kernel identity mapping for use inside the
+ kernel.
+
+ If the region is in kern_memmap, we should use the attribute
+ specified there. Otherwise, if the EFI memory map reports that
+ the entire granule supports WB, we should use that (granules
+ that are partially reserved or occupied by firmware do not appear
+ in kern_memmap). Otherwise, we should use a UC mapping.
+
+PAST PROBLEM CASES
+
+ mmap of various MMIO regions from /dev/mem by "X" on Intel platforms
+
+ The EFI memory map may not report these MMIO regions.
+
+ These must be allowed so that X will work. This means that
+ when the EFI memory map is incomplete, every /dev/mem mmap must
+ succeed. It may create either WB or UC user mappings, depending
+ on whether the region is in kern_memmap or the EFI memory map.
+
+ mmap of 0x0-0xA0000 /dev/mem by "hwinfo" on HP sx1000 with VGA enabled
+
+ See https://bugzilla.novell.com/show_bug.cgi?id=140858.
+
+ The EFI memory map reports the following attributes:
+ 0x00000-0x9FFFF WB only
+ 0xA0000-0xBFFFF UC only (VGA frame buffer)
+ 0xC0000-0xFFFFF WB only
+
+ This mmap is done with user pages, not kernel identity mappings,
+ so it is safe to use WB mappings.
+
+ The kernel VGA driver may ioremap the VGA frame buffer at 0xA0000,
+ which will use a granule-sized UC mapping covering 0-0xFFFFF. This
+ granule covers some WB-only memory, but since UC is non-speculative,
+ the processor will never generate an uncacheable reference to the
+ WB-only areas unless the driver explicitly touches them.
+
+ mmap of 0x0-0xFFFFF legacy_mem by "X"
+
+ If the EFI memory map reports this entire range as WB, there
+ is no VGA MMIO hole, and the mmap should fail or be done with
+ a WB mapping.
+
+ There's no easy way for X to determine whether the 0xA0000-0xBFFFF
+ region is a frame buffer or just memory, so I think it's best to
+ just fail this mmap request rather than using a WB mapping. As
+ far as I know, there's no need to map legacy_mem with WB
+ mappings.
+
+ Otherwise, a UC mapping of the entire region is probably safe.
+ The VGA hole means the region will not be in kern_memmap. The
+ HP sx1000 chipset doesn't support UC access to the memory surrounding
+ the VGA hole, but X doesn't need that area anyway and should not
+ reference it.
+
+ mmap of 0xA0000-0xBFFFF legacy_mem by "X" on HP sx1000 with VGA disabled
+
+ The EFI memory map reports the following attributes:
+ 0x00000-0xFFFFF WB only (no VGA MMIO hole)
+
+ This is a special case of the previous case, and the mmap should
+ fail for the same reason as above.

+A: This is because the size of the suspend image is now greater than

+
+There's the /sys/power/image_size knob that controls the size of the

-- Page migration requires the use of swap handles to preserve the
- information of the anonymous page table entries. This means that swap
- space is reserved but never used. The maximum number of swap handles used
- is determined by CHUNK_SIZE (see mm/mempolicy.c) per ongoing migration.
- Reservation of pages could be avoided by having a special type of swap
- handle that does not require swap space and that would only track the page
- references. Something like that was proposed by Marcelo Tosatti in the
- past (search for migration cache on lkml or linux-mm@kvack.org).
-
-- Page migration unmaps ptes for file backed pages and requires page
- faults to reestablish these ptes. This could be optimized by somehow
- recording the references before migration and then reestablish them later.
- However, there are several locking challenges that have to be overcome
- before this is possible.
-
-- Page migration generates read ptes for anonymous pages. Dirty page
- faults are required to make the pages writable again. It may be possible
- to generate a pte marked dirty if it is known that the page is dirty and
- that this process has the only reference to that page.

+ * So only use this, if device IRQs are masked.
+ * Locking may sleep.
+ * You can sleep within the critical section.
+ * 2) bcm43xx_{un}lock_irqonly():
+ * Takes bcm->irq_lock. Does _not_ protect against
+ * bcm43xx_lock_noirq() critical sections.
+ * Does only protect against the IRQ handler path and other
+ * irqonly() critical sections.
+ * Locking does not sleep.
+ * You must not sleep within the critical section.
+ * 3) bcm43xx_{un}lock_irqsafe():
+ * This is the cummulative lock and takes both, mutex and irq_lock.
+ * Protects against noirq() and irqonly() critical sections (and
+ * the IRQ handler path).
+ * Locking may sleep.

-/* This driver is for the parallel port hardware found on Acorn's old
- * range of Archimedes machines. The A5000 and newer systems have PC-style
- * I/O hardware and should use the parport_pc driver instead.
- *
- * The Acorn printer port hardware is very simple. There is a single 8-bit
- * write-only latch for the data port and control/status bits are handled
- * with various auxilliary input and output lines. The port is not
- * bidirectional, does not support any modes other than SPP, and has only

+ * kmalloc - allocate memory
+ * @size: how many bytes of memory are required.
+ * @flags: the type of memory to allocate.
+ *
+ * kmalloc is the normal method of allocating memory
+ * in the kernel.
+ *
+ * The @flags argument may be one of:
+ *
+ * %GFP_USER - Allocate memory on behalf of user. May sleep.
+ *
+ * %GFP_KERNEL - Allocate normal kernel ram. May sleep.
+ *
+ * %GFP_ATOMIC - Allocation will not sleep.
+ * For example, use this inside interrupt handlers.
+ *
+ * %GFP_HIGHUSER - Allocate pages from high memory.
+ *
+ * %GFP_NOIO - Do not do any I/O at all while trying to get memory.
+ *
+ * %GFP_NOFS - Do not make any fs calls while trying to get memory.
+ *
+ * Also it is possible to set different flags by OR'ing
+ * in one or more of the following additional @flags:
+ *
+ * %__GFP_COLD - Request cache-cold pages instead of
+ * trying to return cache-warm pages.
+ *
+ * %__GFP_DMA - Request memory from the DMA-capable zone.
+ *
+ * %__GFP_HIGH - This allocation has high priority and may use emergency pools.
+ *
+ * %__GFP_HIGHMEM - Allocated memory may be from highmem.
+ *
+ * %__GFP_NOFAIL - Indicate that this allocation is in no way allowed to fail
+ * (think twice before using).
+ *
+ * %__GFP_NORETRY - If memory is not immediately available,
+ * then give up at once.
+ *
+ * %__GFP_NOWARN - If allocation fails, don't issue any warnings.
+ *
+ * %__GFP_REPEAT - If allocation fails initially, try once more before failing.
