      x86/boot/e820: Use 'enum e820_type' in 'struct e820_entry' · 09c51513
      Ingo Molnar authored
      Use a stricter type for struct e820_entry. Add a build-time check to make
      sure the compiler won't ever pack the enum into a field smaller than
      'int'.

      x86/boot/e820: Simplify e820_reserve_resources() · c594761d
      Ingo Molnar authored
      Remove unnecessary duplications of "e820_table->entries[i]." via a local
      variable, plus pass in 'entry' to the type_to_*() functions which further
      improves the readability of the code - and other small tweaks.

      x86/boot/e820: Create coherent API function names for E820 range operations · ab6bc04c
      Ingo Molnar authored
      We have these three related functions:
      
       extern void e820_add_region(u64 start, u64 size, int type);
       extern u64  e820_update_range(u64 start, u64 size, unsigned old_type, unsigned new_type);
       extern u64  e820_remove_range(u64 start, u64 size, unsigned old_type, int checktype);
      
      But it's not clear from the naming that they are 3 operations based around the
      same 'memory range' concept. Rename them to better signal this, and move
      the prototypes next to each other:
      
       extern void e820__range_add   (u64 start, u64 size, int type);
       extern u64  e820__range_update(u64 start, u64 size, unsigned old_type, unsigned new_type);
       extern u64  e820__range_remove(u64 start, u64 size, unsigned old_type, int checktype);
      
      Note that this improved organization of the functions shows another problem that was easy
      to miss before: sometimes the E820 entry type is 'int', sometimes 'unsigned int' - but this
      will be fixed in a separate patch.

      x86/boot/e820: Rename sanitize_e820_table() to e820__update_table() · f52355a9
      Ingo Molnar authored
      sanitize_e820_table() is a minor misnomer in that it suggests that
      the E820 table requires sanitizing - which implies that it will only
      do anything if the E820 table is irregular (not sane).
      
      That is wrong, because sanitize_e820_table() also does a very regular
      sorting of the E820 table, which is a necessity in the basic
      append-only flow of E820 updates the kernel is allowed to perform to
      it.
      
      So rename it to e820__update_table() to include that purpose as well.
      
      This also lines up all the table-update functions into a coherent
      naming family:
      
        int  e820__update_table(struct e820_entry *biosmap, int max_nr_map, u32 *pnr_map);
      
        void e820__update_table_print(void);
        void e820__update_table_firmware(void);
      
      No change in functionality.

      x86/boot/e820: Rename update_e820() to e820__update_table() · 6464d294
      Ingo Molnar authored
      update_e820() should have 'e820' as a prefix as most of the other E820
      functions have - but it's also a bit unclear about its purpose, as
      it's unclear what is updated - the whole table, or an entry?
      
      Also, the name does not express that it's a trivial wrapper
      around sanitize_e820_table() that also prints out the resulting
      table.
      
      So rename it to e820__update_table_print(). This also makes it
      harmonize with the e820__update_table_firmware() function which
      has a very similar purpose.

      x86/boot/e820: Rename early_reserve_e820() to e820__memblock_alloc() and document it · 5da217ca
      Ingo Molnar authored
      early_reserve_e820() is an early hack for kexec that does a limited fixup of the
      mptable and passes it to the kexec kernel as if it was the real thing.
      
      For this it needs to allocate memory - but no memory allocator is available yet
      beyond the memblock allocator, so early_reserve_e820() is really a wrapper
      around memblock_alloc() plus a hack to update the e820_table_firmware entries.
      
      The name 'reserve' is really a bit of a misnomer, as 'reserved' memory typically
      means memory completely inaccessible to the kernel - while here what we want to do
      is a special RAM allocation for our own purposes and insert that as RAM_RESERVED.
      
      Rename the function to e820__memblock_alloc_reserved() to better signal this dual
      purpose, plus document it better, which was omitted when it was merged. The barely
      comprehensible and cryptic comment:
      
        /*
         * pre allocated 4k and reserved it in memblock and e820_table_firmware
         */
        u64 __init e820__memblock_alloc_reserved(u64 size, u64 align)
      
      ... does not count as documentation, replace it with:
      
        /*
         * Allocate the requested number of bytes with the requsted alignment
         * and return (the physical address) to the caller. Also register this
         * range in the 'firmware' E820 table.
         *
         * This allows kexec to fake a new mptable, as if it came from the real
         * system.
         */

      x86/boot/e820: Move the memblock_find_dma_reserve() function and rename it to... · 4270fd8b
      Ingo Molnar authored
      x86/boot/e820: Move the memblock_find_dma_reserve() function and rename it to memblock_set_dma_reserve()
      
      We introduced memblock_find_dma_reserve() in this commit:
      
         6f2a7536 x86, memblock: Use memblock_memory_size()/memblock_free_memory_size() to get correct dma_reserve
      
      But there's several problems with it:
      
       - The changelog is full of typos and is incomprehensible in general, and
         the comments in the code are not much better either.
      
       - The function was inexplicably placed into e820.c, while it has very
         little connection to the E820 table: when we call
         memblock_find_dma_reserve() then memblock is already set up and we
         are not using the E820 table anymore.
      
       - The function is a wrapper around set_dma_reserve(), but changed the 'set'
         name to 'find' - actively misleading about its primary purpose, which is
         still to set the DMA-reserve value.
      
       - The function is limited to 64-bit systems, but neither the changelog nor
         the comments explain why. The change would appear to be relevant to
         32-bit systems as well, as the ISA DMA zone is the first 16 MB of RAM.
      
      So address some of these problems:
      
       - Move it into arch/x86/mm/init.c, next to the other zone setup related
         functions.
      
       - Clean up the code flow and names of local variables a bit.
      
       - Rename it to memblock_set_dma_reserve()
      
       - Improve the comments.
      
      No change in functionality. Enabling it for 32-bit systems is left
      for a separate patch.

      x86/boot/e820: Consolidate 'struct e820_entry *entry' local variable names · e5540f87
      Ingo Molnar authored
      So the E820 code has a lot of cases of:
      
      	struct e820_entry *ei;
      
      ... but the 'ei' name makes very little sense if you think about it, it's
      not an abbreviation of anything obviously related to E820 table entries.
      
      This results in weird looking lines such as:
      
                     if (type && ei->type != type)
      
      where you might have to double check what 'ei' really means, plus
      weird looking secondary variable names, such as:
      
      	u64 ei_end;
      
      The 'ei' name was introduced in a single function over a decade ago, and
      then mindlessly cargo-copied over into other functions - with usage growing
      to over 60 uses altogether (!).
      
      ( My best guess is that it might have been originally meant as abbreviation
        of 'entry interval'. )
      
      Anyway, rename these to the much more obvious:
      
      	struct e820_entry *entry;
      
      No change in functionality.

      x86/boot/e820: Rename memblock_x86_fill() to e820__memblock_setup() and improve the explanations · 4918e228
      Ingo Molnar authored
      So memblock_x86_fill() is another E820 code misnomer:
      
       - nothing in its name tells us that it's part of the E820 subsystem ...
      
       - The 'fill' wording is ambiguous and doesn't tell us whether it's a single
         entry or some process - while the _real_ purpose of the function is hidden,
         which is to do a complete setup of the (platform independent) memblock regions.
      
      So rename it accordingly, to e820__memblock_setup().
      
      Also translate this incomprehensible and misleading comment:
      
              /*
      	 * EFI may have more than 128 entries
      	 * We are safe to enable resizing, beause memblock_x86_fill()
      	 * is rather later for x86
      	 */
              memblock_allow_resize();
      
      The worst aspect of this comment isn't even the sloppy typos, but that it
      casually mentions a '128' number with no explanation, which makes one lead
      to the assumption that this is related to the well-known limit of a maximum
      of 128 E820 entries passed via legacy bootloaders.
      
      But no, the _real_ meaning of 128 here is that of the memblock subsystem,
      which too happens to have a 128 entries limit for very early memblock
      regions (which is unrelated to E820), via INIT_MEMBLOCK_REGIONS ...
      
      So change the comment to a more comprehensible version:
      
              /*
               * The bootstrap memblock region count maximum is 128 entries
               * (INIT_MEMBLOCK_REGIONS), but EFI might pass us more E820 entries
               * than that - so allow memblock resizing.
               *
               * This is safe, because this call happens pretty late during x86 setup,
               * so we know about reserved memory regions already. (This is important
               * so that memblock resizing does no stomp over reserved areas.)
               */
              memblock_allow_resize();
      
      No change in functionality.

      x86/boot/e820: Basic cleanup of e820.c · 640e1b38
      Ingo Molnar authored
      Over the last decade or so e820.c has become an ureadable mess of
      tinkerware. Perform some very basic cleanups before doing more
      intricate cleanups, so that my eyes don't start bleeding when I look at it.
      
      Here's some of the excesses:
      
       - Total disregard of countless aspects of Documentation/CodingStyle.
      
       - Totally inconsistent hodge-podge of various coding styles and practices.
      
       - Gems like:
      
             (unsigned long long) e820_table->entries[i].addr
      
         ... which is a completely unnecessary type conversion of an u64 value.
      
       - Incomprehensible comments while there are major functions with absolutely
         no explanation - plus an armada of typos and grammar mistakes.
      
       - Mindless checkpatch artifacts such as:
      
               if (append_e820_table(boot_params.e820_table, boot_params.e820_entries)
                 < 0) {
      
                 for_each_free_mem_range(u, NUMA_NO_NODE, MEMBLOCK_NONE, &start, &end,
                                         NULL) {
      
       - Actively misleading comments:
      
              /* In case someone cares... */
              return who;
      
         ( The usage site of the return value just a few lines further down makes it
           clear that we very much care about the return value, we use it to print
           out the e820 map... )
      
       - Colorfully inconsistent capitalization and punctuation throughout.
      
       - etc.
      
      This patch fixes only the worst excesses - there's more to fix.

      x86/boot/e820: Rename e820_table_saved to e820_table_firmware and improve the description · 544a0f47
      Ingo Molnar authored
      So the 'e820_table_saved' is a bit of a misnomer that hides its real purpose.
      
      At first sight the name suggests that it's some sort save/restore mechanism,
      as this is how we typically name such facilities in the kernel.
      
      But that is not so, e820_table_saved is the original firmware version of the
      e820 table, not modified by the kernel. This table is displayed in the
      /sys/firmware/memmap file, and it's also used by the hibernation code to
      calculate a physical memory layout MD5 fingerprint checksum which is
      invariant of the kernel.
      
      So rename it to 'e820_table_firmware' and update all the comments to better
      describe the main e820 data strutures.
      
      Also rename:
      
        'initial_e820_table_saved'  =>  'e820_table_firmware_init'
        'e820_update_range_saved'   =>  'e820_update_range_firmware'
      
      ... to better match the new nomenclature.

      The default_machine_specific_memory_setup() is a mouthful and despite the
      many words it doesn't actually tell us clearly what it does.

      x86/boot/e820: Harmonize the 'struct e820_table' fields · bf495573
      Ingo Molnar authored
      So the e820_table->map and e820_table->nr_map names are a bit
      confusing, because it's not clear what a 'map' really means
      (it could be a bitmap, or some other data structure), nor is
      it clear what nr_map means (is it a current index, or some
      other count).
      
      Rename the fields from:
      
       e820_table->map        =>     e820_table->entries
       e820_table->nr_map     =>     e820_table->nr_entries
      
      which makes it abundantly clear that these are entries
      of the table, and that the size of the table is ->nr_entries.
      
      Propagate the changes to all affected files. Where necessary,
      adjust local variable names to better reflect the new field names.

      x86/boot/e820: Rename the basic e820 data types to 'struct e820_entry' and 'struct e820_array' · 8ec67d97
      Ingo Molnar authored
      The 'e820entry' and 'e820map' names have various annoyances:
      
       - the missing underscore departs from the usual kernel style
         and makes the code look weird,
      
       - in the past I kept confusing the 'map' with the 'entry', because
         a 'map' is ambiguous in that regard,
      
       - it's not really clear from the 'e820map' that this is a regular
         C array.
      
      Rename them to 'struct e820_entry' and 'struct e820_array' accordingly.
      
      ( Leave the legacy UAPI header alone but do the rename in the bootparam.h
        and e820/types.h file - outside tools relying on these defines should
        either adjust their code, or should use the legacy header, or should
        create their private copies for the definitions. )

      Ingo Molnar authored
      A commonly used lowlevel x86 header, asm/pgtable.h, includes asm/e820/api.h
      spuriously, without making direct use of it.
      
      Removing it is not simple: over the years various .c code learned to rely
      on this indirect inclusion.
      
      Remove the unnecessary include - this should speed up the kernel build a bit,
      as a large header is not included anymore in totally unrelated code.

      E820_X_MAX is defined in a somewhat messy fashion:
      
       - there's a pretty pointless looking #ifndef __KERNEL__ define that
         makes no sense in the non-UAPI header anymore,
      
       - part of it is defined in api.h, which is not for type definitions,
      
       - plus it's defined in two headers and the main explanation is in the
         header where we don't have the real definition.
      
      So move it into a single place in e820/types.h and get rid of the
      !__KERNEL__ case altogether. Drop the smaller comment - the larger
      one explains it just fine.
      
      Note that the zeropage does not use E820_X_MAX, it uses the legacy
      128 entries definition.
      
      No change in functionality.

      x86/boot/e820: Move asm/e820.h to asm/e820/api.h · 66441bd3
      Ingo Molnar authored
      In line with asm/e820/types.h, move the e820 API declarations to
      asm/e820/api.h and update all usage sites.
      
      This is just a mechanical, obviously correct move & replace patch,
      there will be subsequent changes to clean up the code and to make
      better use of the new header organization.

      Do some common-sense cleanups:
      
       - standardize on the kernel coding style consistently
      
       - tabulate definitions consistently
      
       - extend and clarify various descriptions
      
       - fix speling
      
       - update the header guard name according to the new position
      
       - etc.

      x86/boot/e820: Introduce arch/x86/include/asm/e820/types.h · 70a9d818
      Ingo Molnar authored
      First baby steps towards saner e820 headers: create an exact copy of
      arch/x86/include/uapi/asm/e820.h and use it from the asm/e820.h file.
      
      No other changes - this is done to decouple the code from UAPI headers,
      plus to make sure that subsequent modifications to the file can be more
      clearly seen.
      
      The plan is to keep the old UAPI header in place but the kernel won't
      use it anymore - and after some time we'll try to remove it. (User-space
      tools better have local copies of headers anyway, instead of relying
      on kernel headers.)
      
      This gives the kernel the freedom to reorganize the e820 code.
