2014-08-08x86: Add "make tinyconfig" to configure the tiniest possible kernelJosh Triplett
Since commit 5d2acfc7b974bbd3858b4dd3f2cdc6362dd8843a ("kconfig: make allnoconfig disable options behind EMBEDDED and EXPERT") in 3.15-rc1, "make allnoconfig" disables every possible config option. However, a few configuration options (CC_OPTIMIZE_FOR_SIZE, OPTIMIZE_INLINING) produce a smaller kernel when turned on, and a few choices exist (compression, highmem, allocator) for which a non-default option produces a smaller kernel. Add a "tinyconfig" option, which starts from allnoconfig and then sets these options to configure the tiniest possible kernel. This provides a better baseline for embedded systems or efforts to reduce kernel size. Signed-off-by: Josh Triplett <josh@joshtriplett.org>

2014-02-19ACPI: Remove Kconfig symbol ACPI_PROCFSPaul Bolle
Nothing cares about ACPI_PROCFS. This has been the case since v2.6.38. This Kconfig symbol serves no purpose and its help text is now misleading. It can safely be removed. If this symbol would be needed again in the future it can be readded in a commit that adds code that actually uses it. Signed-off-by: Paul Bolle <pebolle@tiscali.nl> Signed-off-by: Rafael J.

2013-11-04x86, defconfig: Add DEVTMPFS and DEVTMPFS_MOUNT to *86*_defconfigChen Gang
The defconfig kernel can not run under neither fedora16 x86_64 laptop nor fedora17 x86_64 pc. After enable DEVTMPFS* in x86_64_defconfig, it will be OK. DEVTMPFS* is only related with software, so for i386_defconfig may also need them (at least, it has no negative effect for defconfig).

Add an config file snippet which enables additional options useful for running the kernel in a kvm guest.

2012-12-20x86: Default to ARCH=x86 to avoid overriding CONFIG_64BITDavid Woodhouse
It is easy to waste a bunch of time when one takes a 32-bit .config from a test machine and try to build it on a faster 64-bit system, and its existing setting of CONFIG_64BIT=n gets *changed* to match the build host. Similarly, if one has an existing build tree it is easy to trash an entire build tree that way. This is because the default setting for $ARCH when discovered from 'uname' is one of the legacy pre-x86-merge values (i386 or x86_64), which effectively force the setting of CONFIG_64BIT to match. We should default to ARCH=x86 instead, finally completing the merge that we started so long ago. This patch preserves the behaviour of the legacy ARCH settings for commands such as: make ARCH=x86_64 randconfig make ARCH=i386 randconfig ... since making the value of CONFIG_64BIT actually random in that situation is not desirable. In time, perhaps we can retire this legacy use of the old ARCH= values. We already have a way to override values for *any* config option, using $KCONFIG_ALLCONFIG, so it could be argued that we don't necessarily need to keep ARCH={i386,x86_64} around as a special case just for overriding CONFIG_64BIT. We'd probably at least want to add a way to override config options from the command line ('make CONFIG_FOO=y oldconfig') before we talk about doing that though.

2012-09-05x86/Kconfig: Turn off DEBUG_NX_TEST module in defconfigsJosh Triplett
The x86 defconfigs include exactly one module: test_nx.ko, a special-purpose module which just exists to do evil things like executing code off the stack to see if the kernel has enabled NX support. Anyone who actually uses that module can easily enable it themselves, but the vast majority of kernel builds don't need it; disable it by default.

2012-09-05x86/Kconfig: Turn off CONFIG_BLK_DEV_RAMJosh Triplett
The vast majority of systems either use initramfs or mount a root filesystem directly from the kernel. Distros have defaulted to initramfs for years. Only highly specialized systems would use an actual filesystem-image initrd at this point, and such systems don't rely on defconfig anyway. Drop initrd support (and specifically RAM block device support) from the defconfigs.

2011-05-26cgroup: remove the ns_cgroupDaniel Lezcano
The ns_cgroup is an annoying cgroup at the namespace / cgroup frontier and leads to some problems: * cgroup creation is out-of-control * cgroup name can conflict when pids are looping * it is not possible to have a single process handling a lot of namespaces without falling in a exponential creation time * we may want to create a namespace without creating a cgroup The ns_cgroup was replaced by a compatibility flag 'clone_children', where a newly created cgroup will copy the parent cgroup values. The userspace has to manually create a cgroup and add a task to the 'tasks' file. This patch removes the ns_cgroup as suggested in the following thread: https://lists.linux-foundation.org/pipermail/containers/2009-June/018616.html The 'cgroup_clone' function is removed because it is no longer used. This is a userspace-visible change. Commit 45531757b45c ("cgroup: notify ns_cgroup deprecated") (merged into 2.6.27) caused the kernel to emit a printk warning users that the feature is planned for removal. Since that time we have heard from XXX users who were affected by this. Signed-off-by: Daniel Lezcano <daniel.lezcano@free.fr> Signed-off-by: Serge E. Hallyn <serge.hallyn@canonical.com> Cc: Eric W.

2010-08-03x86, hwmon: Package Level Thermal/Power: pkgtemp hwmon driverFenghua Yu
This patch adds a hwmon driver for package level thermal control. The driver dumps package level thermal information through sysfs interface so that upper level application (e.g. lm_sensor) can retrive the information. Instead of having the package level hwmon code in coretemp, I write a seperate driver pkgtemp because: First, package level thermal sensors include not only sensors for each core, but also sensors for uncore, memory controller or other components in the package. Logically it will be clear to have a seperate hwmon driver for package level hwmon to monitor wider range of sensors in a package. Merging package thermal driver into core thermal driver doesn't make sense and may mislead. Secondly, merging the two drivers together may cause coding mess. It's easier to include various package level sensors info if more sensor information is implemented. Coretemp code needs to consider a lot of legacy machine cases. Pkgtemp code only considers platform starting from Sandy Bridge. On a 1Sx4Cx2T Sandy Bridge platform, lm-sensors dumps the pkgtemp and coretemp: pkgtemp-isa-0000 Adapter: ISA adapter physical id 0: +33.0°C (high = +79.0°C, crit = +99.0°C) coretemp-isa-0000 Adapter: ISA adapter Core 0: +32.0°C (high = +79.0°C, crit = +99.0°C) coretemp-isa-0001 Adapter: ISA adapter Core 1: +32.0°C (high = +79.0°C, crit = +99.0°C) coretemp-isa-0002 Adapter: ISA adapter Core 2: +32.0°C (high = +79.0°C, crit = +99.0°C) coretemp-isa-0003 Adapter: ISA adapter Core 3: +32.0°C (high = +79.0°C, crit = +99.0°C) [ hpa: folded v3 patch removing improper global variable "SHOW" ] Signed-off-by: Fenghua Yu <fenghua.yu@intel.com> LKML-Reference: <1280448826-12004-3-git-send-email-fenghua.yu@intel.com> Reviewed-by: Len Brown <len.brown@intel.com> Signed-off-by: H.

2009-02-23x86: remove the Voyager 32-bit subarchIngo Molnar
Impact: remove unused/broken code The Voyager subarch last built successfully on the v2.6.26 kernel and has been stale since then and does not build on the v2.6.27, v2.6.28 and v2.6.29-rc5 kernels. No actual users beyond the maintainer reported this breakage. Patches were sent and most of the fixes were accepted but the discussion around how to do a few remaining issues cleanly fizzled out with no resolution and the code remained broken. In the v2.6.30 x86 tree development cycle 32-bit subarch support has been reworked and removed - and the Voyager code, beyond the build problems already known, needs serious and significant changes and probably a rewrite to support it. CONFIG_X86_VOYAGER has been marked BROKEN then. The maintainer has been notified but no patches have been sent so far to fix it. While all other subarchs have been converted to the new scheme, voyager is still broken. We'd prefer to receive patches which clean up the current situation in a constructive way, but even in case of removal there is no obstacle to add that support back after the issues have been sorted out in a mutually acceptable fashion. So remove this inactive code for now. Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-09-05x86: additional defconfig updatesH. Peter Anvin
Additional updates to the x86 defconfigs. The goals are, as before: - Make them usable to testers, more so than distributors or end users, both of which are likely to have their own config already. - Keep 32 and 64 bits as similar as is practical. Changes: - Use a more generic CPU type (ppro and generic, respectively). - Bump number of CPUs to 64 (few if any NR_CPUS arrays left). - Enable PAT. - Enable OPTIMIZE_INLINE. - Enable microcode update support. - Build SMT scheduler support (in addition to MC).

2008-09-03x86 setup: remove remnants of CONFIG_VIDEO_SELECT (read: vga=)Alexey Dobriyan
Impact: cleanup Video mode selection became always possible in 2.6.23-rc1 after i386 setup code rewrite in C. Regardless, VIDEO_SELECT is stupid config option because it affects only kernel setup code, not code which always stays in memory. vga= always possible now which is good.

2008-07-20Subject: devmem, x86: fix rename of CONFIG_NONPROMISC_DEVMEMIngo Molnar
From: Arjan van de Ven <arjan@infradead.org> Date: Sat, 19 Jul 2008 15:47:17 -0700 CONFIG_NONPROMISC_DEVMEM was a rather confusing name - but renaming it to CONFIG_PROMISC_DEVMEM causes problems on architectures that do not support this feature; this patch renames it to CONFIG_STRICT_DEVMEM, so that architectures can opt-in into it. ( the polarity of the option is still the same as it was originally; it needs to be for now to not break architectures that don't have the infastructure yet to support this feature) Signed-off-by: Arjan van de Ven <arjan@linux.intel.com> Cc: "V.Radhakrishnan" <rk@atr-labs.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> ---

2008-04-26x86: add optimized inliningIngo Molnar
add CONFIG_OPTIMIZE_INLINING=y. allow gcc to optimize the kernel image's size by uninlining functions that have been marked 'inline'. Previously gcc was forced by Linux to always-inline these functions via a gcc attribute: #define inline inline __attribute__((always_inline)) Especially when the user has already selected CONFIG_OPTIMIZE_FOR_SIZE=y this can make a huge difference in kernel image size (using a standard Fedora .config): text data bss dec hex filename 5613924 562708 3854336 10030968 990f78 vmlinux.before 5486689 562708 3854336 9903733 971e75 vmlinux.after that's a 2.3% text size reduction (!).

2008-01-30x86: 64-bit, make sparsemem vmemmap the only memory modelChristoph Lameter
Use sparsemem as the only memory model for UP, SMP and NUMA. Measurements indicate that DISCONTIGMEM has a higher overhead than sparsemem. And FLATMEMs benefits are minimal. So I think its best to simply standardize on sparsemem. Results of page allocator tests (test can be had via git from slab git tree branch tests) Measurements in cycle counts. 1000 allocations were performed and then the average cycle count was calculated.
