      kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT · 6a108a14
      David Rientjes 提交于
      The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
      is used to configure any non-standard kernel with a much larger scope than
      only small devices.
      
      This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
      references to the option throughout the kernel.  A new CONFIG_EMBEDDED
      option is added that automatically selects CONFIG_EXPERT when enabled and
      can be used in the future to isolate options that should only be
      considered for embedded systems (RISC architectures, SLOB, etc).
      
      Calling the option "EXPERT" more accurately represents its intention: only
      expert users who understand the impact of the configuration changes they
      are making should enable it.

      sysfs: add /sys/firmware/memmap · 69ac9cd6
      Bernhard Walle 提交于
      This patch adds /sys/firmware/memmap interface that represents the BIOS
      (or Firmware) provided memory map. The tree looks like:
      
          /sys/firmware/memmap/0/start   (hex number)
                                 end     (hex number)
                                 type    (string)
          ...                 /1/start
                                 end
                                 type
      
      With the following shell snippet one can print the memory map in the same form
      the kernel prints itself when booting on x86 (the E820 map).
      
        --------- 8< --------------------------
          #!/bin/sh
          cd /sys/firmware/memmap
          for dir in * ; do
              start=$(cat $dir/start)
              end=$(cat $dir/end)
              type=$(cat $dir/type)
              printf "%016x-%016x (%s)\n" $start $[ $end +1] "$type"
          done
        --------- >8 --------------------------
      
      That patch only provides the needed interface:
      
       1. The sysfs interface.
       2. The structure and enumeration definition.
       3. The function firmware_map_add() and firmware_map_add_early()
          that should be called from architecture code (E820/EFI, for
          example) to add the contents to the interface.
      
      If the kernel is compiled without CONFIG_FIRMWARE_MEMMAP, the interface does
      nothing without cluttering the architecture-specific code with #ifdef's.
      
      The purpose of the new interface is kexec: While /proc/iomem represents
      the *used* memory map (e.g. modified via kernel parameters like 'memmap'
      and 'mem'), the /sys/firmware/memmap tree represents the unmodified memory
      map provided via the firmware. So kexec can:
      
       - use the original memory map for rebooting,
       - use the /proc/iomem for setting up the ELF core headers for kdump
         case that should only represent the memory of the system.
      
      The patch has been tested on i386 and x86_64.

      Firmware: add iSCSI iBFT Support · 138fe4e0
      Konrad Rzeszutek 提交于
      Add /sysfs/firmware/ibft/[initiator|targetX|ethernetX] directories along with
      text properties which export the the iSCSI Boot Firmware Table (iBFT)
      structure.
      
      What is iSCSI Boot Firmware Table?  It is a mechanism for the iSCSI tools to
      extract from the machine NICs the iSCSI connection information so that they
      can automagically mount the iSCSI share/target.  Currently the iSCSI
      information is hard-coded in the initrd.  The /sysfs entries are read-only
      one-name-and-value fields.
      
      The usual set of data exposed is:
      
      # for a in `find /sys/firmware/ibft/ -type f -print`; do  echo -n "$a: ";  cat $a; done

      DMI-based module autoloading · 4f5c791a
      Lennart Poettering 提交于
      The patch below adds DMI/SMBIOS based module autoloading to the Linux
      kernel. The idea is to load laptop drivers automatically (and other
      drivers which cannot be autoloaded otherwise), based on the DMI system
      identification information of the BIOS.
      
      Right now most distros manually try to load all available laptop
      drivers on bootup in the hope that at least one of them loads
      successfully. This patch does away with all that, and uses udev to
      automatically load matching drivers on the right machines.
      
      Basically the patch just exports the DMI information that has been
      parsed by the kernel anyway to userspace via a sysfs device
      /sys/class/dmi/id and makes sure that proper modalias attributes are
      available. Besides adding the "modalias" attribute it also adds
      attributes for a few other DMI fields which might be useful for
      writing udev rules.
      
      This patch is not an attempt to export the entire DMI/SMBIOS data to
      userspace. We already have "dmidecode" which parses the complete DMI
      info from userspace. The purpose of this patch is machine model
      identification and good udev integration.
      
      To take advantage of DMI based module autoloading, a driver should
      export one or more MODULE_ALIAS fields similar to these:
      
      MODULE_ALIAS("dmi:*:svnMICRO-STARINT'LCO.,LTD:pnMS-1013:pvr0131*:cvnMICRO-STARINT'LCO.,LTD:ct10:*");
      MODULE_ALIAS("dmi:*:svnMicro-StarInternational:pnMS-1058:pvr0581:rvnMSI:rnMS-1058:*:ct10:*");
      MODULE_ALIAS("dmi:*:svnMicro-StarInternational:pnMS-1412:*:rvnMSI:rnMS-1412:*:cvnMICRO-STARINT'LCO.,LTD:ct10:*");
      MODULE_ALIAS("dmi:*:svnNOTEBOOK:pnSAM2000:pvr0131*:cvnMICRO-STARINT'LCO.,LTD:ct10:*");
      
      These lines are specific to my msi-laptop.c driver. They are basically
      just a concatenation of a few carefully selected DMI fields with all
      potentially bad characters stripped.
      
      Besides laptop drivers, modules like "hdaps", the i2c modules
      and the hwmon modules are good candidates for "dmi:" MODULE_ALIAS
      lines.
      
      Besides merely exporting the DMI data via sysfs the patch adds
      support for a few more DMI fields. Especially the CHASSIS fields are
      very useful to identify different laptop modules. The patch also adds
      working MODULE_ALIAS lines to my msi-laptop.c driver.
      
      I'd like to thank Kay Sievers for helping me to clean up this patch
      for posting it on lkml.
      
      Patch is against Linus' current GIT HEAD. Should probably apply to
      older kernels as well without modification.

      Linux-2.6.12-rc2 · 1da177e4
      Linus Torvalds 提交于
      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
