The driver goes under drives/nfc/ and is compiled as a +module named "pn544". It registers a misc device and creates a device +file named "/dev/pn544". + +Host Interfaces: I2C, SPI and HSU, this driver supports currently only I2C. + +The Interface +------------- + +The driver offers a sysfs interface for a hardware test and an IOCTL +interface for selecting between two operating modes. There are read, +write and poll functions for transferring messages. The two operating +modes are the normal (HCI) mode and the firmware update mode. + +PN544 is controlled by sending messages from the userspace to the +chip. The main function of the driver is just to pass those messages +without caring about the message content. + + +Protocols +--------- + +In the normal (HCI) mode and in the firmware update mode read and +write functions behave a bit differently because the message formats +or the protocols are different. + +In the normal (HCI) mode the protocol used is derived from the ETSI +HCI specification. The firmware is updated using a specific protocol, +which is different from HCI. + +HCI messages consist of an eight bit header and the message body. The +header contains the message length. Maximum size for an HCI message is +33. In HCI mode sent messages are tested for a correct +checksum. Firmware update messages have the length in the second (MSB) +and third (LSB) bytes of the message. The maximum FW message length is +1024 bytes. + +For the ETSI HCI specification see +http://www.etsi.org/WebSite/Technologies/ProtocolSpecification.aspx + +The Hardware Test +----------------- + +The idea of the test is that it can performed by reading from the +corresponding sysfs file. The test is implemented in the board file +and it should test that PN544 can be put into the firmware update +mode. If the test is not implemented the sysfs file does not get +created. + +Example: +> cat /sys/module/pn544/drivers/i2c\:pn544/3-002b/nfc_test +1 + +Normal Operation +---------------- + +PN544 is powered up when the device file is opened, otherwise it's +turned off. Only one instance can use the device at a time. + +Userspace applications control PN544 with HCI messages. The hardware +sends an interrupt when data is available for reading. Data is +physically read when the read function is called by a userspace +application. Poll() checks the read interrupt state. Configuration and +self testing are also done from the userspace using read and write. + +Example platform data: + +static int rx71_pn544_nfc_request_resources(struct i2c_client *client) +{ + /* Get and setup the HW resources for the device */ +} + +static void rx71_pn544_nfc_free_resources(void) +{ + /* Release the HW resources */ +} + +static void rx71_pn544_nfc_enable(int fw) +{ + /* Turn the device on */ +} + +static int rx71_pn544_nfc_test(void) +{ + /* + * Put the device into the FW update mode + * and then back to the normal mode. + * Check the behavior and return one on success, + * zero on failure. + */ +} + +static void rx71_pn544_nfc_disable(void) +{ + /* turn the power off */ +} + +static struct pn544_nfc_platform_data rx71_nfc_data = { + .request_resources = rx71_pn544_nfc_request_resources, + .free_resources = rx71_pn544_nfc_free_resources, + .enable = rx71_pn544_nfc_enable, + .test = rx71_pn544_nfc_test, + .disable = rx71_pn544_nfc_disable, +}; diff --git a/Documentation/powerpc/booting-without-of.txt b/Documentation/powerpc/booting-without-of.txt index 3272ed59dec7..7400d7555dc3 100644 --- a/Documentation/powerpc/booting-without-of.txt +++ b/Documentation/powerpc/booting-without-of.txt @@ -1098,7 +1098,7 @@ supported currently at the toplevel. * an arbitrary array of bytes */ - childnode@addresss { /* define a child node named "childnode" + childnode@address { /* define a child node named "childnode" * whose unit name is "childnode at * address" */ diff --git a/Documentation/pps/pps.txt b/Documentation/pps/pps.txt index 125f4ab48998..d35dcdd82ff6 100644 --- a/Documentation/pps/pps.txt +++ b/Documentation/pps/pps.txt @@ -170,3 +170,49 @@ and the run ppstest as follow: Please, note that to compile userland programs you need the file timepps.h (see Documentation/pps/). + + +Generators +---------- + +Sometimes one needs to be able not only to catch PPS signals but to produce +them also.

Transparent Hugepage Support is an alternative means of +using huge pages for the backing of virtual memory with huge pages +that supports the automatic promotion and demotion of page sizes and +without the shortcomings of hugetlbfs. + +Currently it only works for anonymous memory mappings but in the +future it can expand over the pagecache layer starting with tmpfs. + +The reason applications are running faster is because of two +factors. The first factor is almost completely irrelevant and it's not +of significant interest because it'll also have the downside of +requiring larger clear-page copy-page in page faults which is a +potentially negative effect. The first factor consists in taking a +single page fault for each 2M virtual region touched by userland (so +reducing the enter/exit kernel frequency by a 512 times factor). This +only matters the first time the memory is accessed for the lifetime of +a memory mapping. The second long lasting and much more important +factor will affect all subsequent accesses to the memory for the whole +runtime of the application. The second factor consist of two +components: 1) the TLB miss will run faster (especially with +virtualization using nested pagetables but almost always also on bare +metal without virtualization) and 2) a single TLB entry will be +mapping a much larger amount of virtual memory in turn reducing the +number of TLB misses. With virtualization and nested pagetables the +TLB can be mapped of larger size only if both KVM and the Linux guest +are using hugepages but a significant speedup already happens if only +one of the two is using hugepages just because of the fact the TLB +miss is going to run faster. + +== Design == + +- "graceful fallback": mm components which don't have transparent + hugepage knowledge fall back to breaking a transparent hugepage and + working on the regular pages and their respective regular pmd/pte + mappings + +- if a hugepage allocation fails because of memory fragmentation, + regular pages should be gracefully allocated instead and mixed in + the same vma without any failure or significant delay and without + userland noticing + +- if some task quits and more hugepages become available (either + immediately in the buddy or through the VM), guest physical memory + backed by regular pages should be relocated on hugepages + automatically (with khugepaged) + +- it doesn't require memory reservation and in turn it uses hugepages + whenever possible (the only possible reservation here is kernelcore= + to avoid unmovable pages to fragment all the memory but such a tweak + is not specific to transparent hugepage support and it's a generic + feature that applies to all dynamic high order allocations in the + kernel) + +- this initial support only offers the feature in the anonymous memory + regions but it'd be ideal to move it to tmpfs and the pagecache + later + +Transparent Hugepage Support maximizes the usefulness of free memory +if compared to the reservation approach of hugetlbfs by allowing all +unused memory to be used as cache or other movable (or even unmovable +entities).

So to make them effective you need to restart any +application that could have been using hugepages. This also applies to +the regions registered in khugepaged. + +== get_user_pages and follow_page == + +get_user_pages and follow_page if run on a hugepage, will return the +head or tail pages as usual (exactly as they would do on +hugetlbfs). Most gup users will only care about the actual physical +address of the page and its temporary pinning to release after the I/O +is complete, so they won't ever notice the fact the page is huge. But +if any driver is going to mangle over the page structure of the tail +page (like for checking page->mapping or other bits that are relevant +for the head page and not the tail page), it should be updated to jump +to check head page instead (while serializing properly against +split_huge_page() to avoid the head and tail pages to disappear from +under it, see the futex code to see an example of that, hugetlbfs also +needed special handling in futex code for similar reasons). + +NOTE: these aren't new constraints to the GUP API, and they match the +same constrains that applies to hugetlbfs too, so any driver capable +of handling GUP on hugetlbfs will also work fine on transparent +hugepage backed mappings. + +In case you can't handle compound pages if they're returned by +follow_page, the FOLL_SPLIT bit can be specified as parameter to +follow_page, so that it will split the hugepages before returning +them. Migration for example passes FOLL_SPLIT as parameter to +follow_page because it's not hugepage aware and in fact it can't work +at all on hugetlbfs (but it instead works fine on transparent +hugepages thanks to FOLL_SPLIT). migration simply can't deal with +hugepages being returned (as it's not only checking the pfn of the +page and pinning it during the copy but it pretends to migrate the +memory in regular page sizes and with regular pte/pmd mappings). + +== Optimizing the applications == + +To be guaranteed that the kernel will map a 2M page immediately in any +memory region, the mmap region has to be hugepage naturally +aligned. posix_memalign() can provide that guarantee. + +== Hugetlbfs == + +You can use hugetlbfs on a kernel that has transparent hugepage +support enabled just fine as always. No difference can be noted in +hugetlbfs other than there will be less overall fragmentation. All +usual features belonging to hugetlbfs are preserved and +unaffected. libhugetlbfs will also work fine as usual. + +== Graceful fallback == + +Code walking pagetables but unware about huge pmds can simply call +split_huge_page_pmd(mm, pmd) where the pmd is the one returned by +pmd_offset. It's trivial to make the code transparent hugepage aware +by just grepping for "pmd_offset" and adding split_huge_page_pmd where +missing after pmd_offset returns the pmd. Thanks to the graceful +fallback design, with a one liner change, you can avoid to write +hundred if not thousand of lines of complex code to make your code +hugepage aware. + +If you're not walking pagetables but you run into a physical hugepage +but you can't handle it natively in your code, you can split it by +calling split_huge_page(page).

You must hold the +mmap_sem in read (or write) mode to be sure an huge pmd cannot be +created from under you by khugepaged (khugepaged collapse_huge_page +takes the mmap_sem in write mode in addition to the anon_vma lock). If +pmd_trans_huge returns false, you just fallback in the old code +paths. If instead pmd_trans_huge returns true, you have to take the +mm->page_table_lock and re-run pmd_trans_huge. Taking the +page_table_lock will prevent the huge pmd to be converted into a +regular pmd from under you (split_huge_page can run in parallel to the +pagetable walk). If the second pmd_trans_huge returns false, you +should just drop the page_table_lock and fallback to the old code as +before. Otherwise you should run pmd_trans_splitting on the pmd. In +case pmd_trans_splitting returns true, it means split_huge_page is +already in the middle of splitting the page. So if pmd_trans_splitting +returns true it's enough to drop the page_table_lock and call +wait_split_huge_page and then fallback the old code paths. You are +guaranteed by the time wait_split_huge_page returns, the pmd isn't +huge anymore. If pmd_trans_splitting returns false, you can proceed to +process the huge pmd and the hugepage natively. Once finished you can +drop the page_table_lock. + +== compound_lock, get_user_pages and put_page == + +split_huge_page internally has to distribute the refcounts in the head +page to the tail pages before clearing all PG_head/tail bits from the +page structures. It can do that easily for refcounts taken by huge pmd +mappings. But the GUI API as created by hugetlbfs (that returns head +and tail pages if running get_user_pages on an address backed by any +hugepage), requires the refcount to be accounted on the tail pages and +not only in the head pages, if we want to be able to run +split_huge_page while there are gup pins established on any tail +page. Failure to be able to run split_huge_page if there's any gup pin +on any tail page, would mean having to split all hugepages upfront in +get_user_pages which is unacceptable as too many gup users are +performance critical and they must work natively on hugepages like +they work natively on hugetlbfs already (hugetlbfs is simpler because +hugetlbfs pages cannot be splitted so there wouldn't be requirement of +accounting the pins on the tail pages for hugetlbfs). If we wouldn't +account the gup refcounts on the tail pages during gup, we won't know +anymore which tail page is pinned by gup and which is not while we run +split_huge_page. But we still have to add the gup pin to the head page +too, to know when we can free the compound page in case it's never +splitted during its lifetime. That requires changing not just +get_page, but put_page as well so that when put_page runs on a tail +page (and only on a tail page) it will find its respective head page, +and then it will decrease the head page refcount in addition to the +tail page refcount. To obtain a head page reliably and to decrease its +refcount without race conditions, put_page has to serialize against +__split_huge_page_refcount using a special per-page lock called +compound_lock. diff --git a/Documentation/w1/slaves/00-INDEX b/Documentation/w1/slaves/00-INDEX index f8101d6b07b7..75613c9ac4db 100644 --- a/Documentation/w1/slaves/00-INDEX +++ b/Documentation/w1/slaves/00-INDEX @@ -2,3 +2,5 @@ - This file w1_therm - The Maxim/Dallas Semiconductor ds18*20 temperature sensor. +w1_ds2423 + - The Maxim/Dallas Semiconductor ds2423 counter device. diff --git a/Documentation/w1/slaves/w1_ds2423 b/Documentation/w1/slaves/w1_ds2423 new file mode 100644 index 000000000000..90a65d23cf59 --- /dev/null +++ b/Documentation/w1/slaves/w1_ds2423 @@ -0,0 +1,47 @@ +Kernel driver w1_ds2423 +======================= + +Supported chips: + * Maxim DS2423 based counter devices. + +supported family codes: + W1_THERM_DS2423 0x1D + +Author: Mika Laitio + +Description +----------- + +Support is provided through the sysfs w1_slave file.

Its API is the + same as in other decompress_*.c files, which is defined in + include/linux/decompress/generic.h. + + scripts/xz_wrap.sh is a wrapper for the xz command line tool found + from XZ Utils. The wrapper sets compression options to values suitable + for compressing the kernel image. + + For kernel makefiles, two commands are provided for use with + $(call if_needed). The kernel image should be compressed with + $(call if_needed,xzkern) which will use a BCJ filter and a big LZMA2 + dictionary. It will also append a four-byte trailer containing the + uncompressed size of the file, which is needed by the boot code. + Other things should be compressed with $(call if_needed,xzmisc) + which will use no BCJ filter and 1 MiB LZMA2 dictionary. + +Notes on compression options + + Since the XZ Embedded supports only streams with no integrity check or + CRC32, make sure that you don't use some other integrity check type + when encoding files that are supposed to be decoded by the kernel. With + liblzma, you need to use either LZMA_CHECK_NONE or LZMA_CHECK_CRC32 + when encoding. With the xz command line tool, use --check=none or + --check=crc32. + + Using CRC32 is strongly recommended unless there is some other layer + which will verify the integrity of the uncompressed data anyway. + Double checking the integrity would probably be waste of CPU cycles. + Note that the headers will always have a CRC32 which will be validated + by the decoder; you can only change the integrity check type (or + disable it) for the actual uncompressed data. + + In userspace, LZMA2 is typically used with dictionary sizes of several + megabytes. The decoder needs to have the dictionary in RAM, thus big + dictionaries cannot be used for files that are intended to be decoded + by the kernel. 1 MiB is probably the maximum reasonable dictionary + size for in-kernel use (maybe more is OK for initramfs).

Example: + + xz --check=crc32 --lzma2=dict=512KiB inputfile + + An exception to above dictionary size limitation is when the decoder + is used in single-call mode.

LZMA2 is slower to compress than e.g. Deflate or LZO even at + the fastest settings, so it isn't clear if LZMA2 encoder is wanted + into the kernel. + + Support for limited random-access reading is planned for the + decompression code.

Block Headers of possible + * additional Blocks have to be taken into account still. With these + * assumptions, it is safe to assume that the total header overhead is + * less than 128 bytes. + * + * Compressed Data contains LZMA2 or BCJ+LZMA2 encoded data. Since BCJ + * doesn't change the size of the data, it is enough to calculate the + * safety margin for LZMA2. + * + * LZMA2 stores the data in chunks. Each chunk has a header whose size is + * a maximum of 6 bytes, but to get round 2^n numbers, let's assume that + * the maximum chunk header size is 8 bytes. After the chunk header, there + * may be up to 64 KiB of actual payload in the chunk. Often the payload is + * quite a bit smaller though; to be safe, let's assume that an average + * chunk has only 32 KiB of payload. + * + * The maximum uncompressed size of the payload is 2 MiB. The minimum + * uncompressed size of the payload is in practice never less than the + * payload size itself. The LZMA2 format would allow uncompressed size + * to be less than the payload size, but no sane compressor creates such + * files. LZMA2 supports storing uncompressible data in uncompressed form, + * so there's never a need to create payloads whose uncompressed size is + * smaller than the compressed size. + * + * The assumption, that the uncompressed size of the payload is never + * smaller than the payload itself, is valid only when talking about + * the payload as a whole. It is possible that the payload has parts where + * the decompressor consumes more input than it produces output. Calculating + * the worst case for this would be tricky. Instead of trying to do that, + * let's simply make sure that the decompressor never overwrites any bytes + * of the payload which it is currently reading. + * + * Now we have enough information to calculate the safety margin. We need + * - 128 bytes for the .xz file format headers; + * - 8 bytes per every 32 KiB of uncompressed size (one LZMA2 chunk header + * per chunk, each chunk having average payload size of 32 KiB); and + * - 64 KiB (biggest possible LZMA2 chunk payload size) to make sure that + * the decompressor never overwrites anything from the LZMA2 chunk + * payload it is currently reading. + * + * We get the following formula: + * + * safety_margin = 128 + uncompressed_size * 8 / 32768 + 65536 + * = 128 + (uncompressed_size >> 12) + 65536 + * + * For comparision, according to arch/x86/boot/compressed/misc.c, the + * equivalent formula for Deflate is this: + * + * safety_margin = 18 + (uncompressed_size >> 12) + 32768 + * + * Thus, when updating Deflate-only in-place kernel decompressor to + * support XZ, the fixed overhead has to be increased from 18+32768 bytes + * to 128+65536 bytes. + */ + +/* + * STATIC is defined to "static" if we are being built for kernel + * decompression (pre-boot code). will define + * STATIC to empty if it wasn't already defined.
