* alpha: Reorganize rtc handlingRichard Henderson2013-11-161-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | Discontinue use of GENERIC_CMOS_UPDATE; rely on the RTC subsystem. The marvel platform requires that the rtc only be touched from the boot cpu. This had been partially implemented with hooks for get/set_rtc_time, but read/update_persistent_clock were not handled. Move the hooks from the machine_vec to a special rtc_class_ops struct. We had read_persistent_clock managing the epoch against which the rtc hw is based, but this didn't apply to get_rtc_time or set_rtc_time. This resulted in incorrect values when hwclock(8) gets involved. Allow the epoch to be set from the kernel command-line, overriding the autodetection, which is doomed to fail in 2020. Further, by implementing the rtc ioctl function, we can expose this epoch to userland. Elide the alarm functions that RTC_DRV_CMOS implements. This was highly questionable on Alpha, since the interrupt is used by the system timer. Signed-off-by: Richard Henderson <rth@twiddle.net>

* alpha: implement HW performance events on the EV67 and later CPUsMichael Cree2010-08-091-0/+1
| | | | | | | | | | | | | | | | | | | | | This implements hardware performance events for the EV67 and later CPUs within the Linux performance events subsystem. Only using the performance monitoring unit in HP/Compaq's so called "Aggregrate mode" is supported. The code has been implemented in a manner that makes extension to other older Alpha CPUs relatively straightforward should some mug wish to indulge themselves.

* alpha: Detect Super IO chip, no IDE on Avanti, enable EPP19Morten H. Larsen2010-06-151-10/+10
| | | | | | | | | This patch probes for the Super IO chip and reserves the IO range when found. It avoids enabling the IDE interface on the Avanti family, since none has IDE. It enables the Enhanced Parallel Port v1.9 feature. Signed-off-by: Morten H. Larsen <m-larsen@post6.tele.dk> Signed-off-by: Matt Turner <mattst88@gmail.com>
* alpha: binfmt_aout fixIvan Kokshaysky2009-05-021-1/+5
| | | | | | | | | | | | | | | | | | | | | This fixes the problem introduced by commit 3bfacef412 (get rid of special-casing the /sbin/loader on alpha): osf/1 ecoff binary segfaults when binfmt_aout built as module. That happens because aout binary handler gets on the top of the binfmt list due to late registration, and kernel attempts to execute the binary without preparatory work that must be done by binfmt_loader. Fixed by changing the registration order of the default binfmt handlers using list_add_tail() and introducing insert_binfmt() function which places new handler on the top of the binfmt list. This might be generally useful for installing arch-specific frontends for default handlers or just for overriding them.

* PCI/alpha: pci sysfs resourcesIvan Kokshaysky2009-03-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This closes http://bugzilla.kernel.org/show_bug.cgi?id=10893 which is a showstopper for X development on alpha. The generic HAVE_PCI_MMAP code (drivers/pci-sysfs.c) is not very useful since we have to deal with three different types of MMIO address spaces: sparse and dense mappings for old ev4/ev5 machines and "normal" 1:1 MMIO space (bwx) for ev56 and later. Also "write combine" mappings are meaningless on alpha - roughly speaking, alpha does write combining, IO reordering and other optimizations by default, unless user splits IO accesses with memory barriers. I think the cleanest way to deal with resource files on alpha is to convert the default no-op pci_create_resource_files() and pci_remove_resource_files() for !HAVE_PCI_MMAP case into __weak functions and override them with alpha specific ones. Another alpha hook is needed for "legacy_" resource files to handle sparse addressing (pci_adjust_legacy_attr). With the "standard" resourceN files on ev56/ev6 libpciaccess works "out of the box". Handling of resourceN_sparse/resourceN_dense files on older machines obviously requires some userland work. Sparse/dense stuff has been tested on sx164 (pca56/pyxis, normally uses bwx IO) with the kernel hacked into "cia compatible" mode.

* Generic semaphore implementationMatthew Wilcox2008-04-171-1/+1
| | | | | | | | | | | Semaphores are no longer performance-critical, so a generic C implementation is better for maintainability, debuggability and extensibility. Thanks to Peter Zijlstra for fixing the lockdep warning. Thanks to Harvey Harrison for pointing out that the unlikely() was unnecessary.

* kbuild: enable 'make CFLAGS=...' to add additional options to CCSam Ravnborg2007-10-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | The variable CFLAGS is a wellknown variable and the usage by kbuild may result in unexpected behaviour. On top of that several people over time has asked for a way to pass in additional flags to gcc. This patch replace use of CFLAGS with KBUILD_CFLAGS all over the tree and enabling one to use: make CFLAGS=... to specify additional gcc commandline options. One usecase is when trying to find gcc bugs but other use cases has been requested too. Patch was tested on following architectures: alpha, arm, i386, x86_64, mips, sparc, sparc64, ia64, m68k Test was simple to do a defconfig build, apply the patch and check that nothing got rebuild.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-161-0/+104
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!
