2005-07-06[IA64] hotplug/ia64: SN Hotplug Driver - SN Hotplug Driver codePrarit Bhargava
This patch is the SGI hotplug driver and additional changes required for the driver. These modifications include changes to the SN io_init.c code for memory management, the inclusion of new SAL calls to enable and disable PCI slots, and a hotplug-style driver.

2005-07-06[IA64] hotplug/ia64: SN Hotplug Driver - new SN PROM version codePrarit Bhargava
This patch is a rewrite of the code to check the PROM version. The current code has some deficiences in the way PROM comparisons were made. The minimum value of PROM that will boot has also been changed to 4.04. Signed-off-by: Prarit Bhargava <prarit@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
2005-07-06[IA64] hotplug/ia64: SN Hotplug Driver: moving of header filesPrarit Bhargava
This patch moves header files out of the arch/ia64/sn directories and into include/asm-ia64/sn. These files were being included by other subsystems and should be under include/asm-ia64/sn. Signed-off-by: Prarit Bhargava <prarit@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
2005-07-06[IA64] hotplug/ia64: SN Hotplug Driver: SN IRQ FixesPrarit Bhargava
This patch fixes the SN IRQ code such that cpu affinity and Hotplug can modify IRQ values. The sn_irq_info structures are now locked using a RCU lock mechanism to avoid lock contention in the lost interrupt WAR code.

2005-06-28[IA64] sparse cleanup of shub_mmr.hPrarit Bhargava
This patch is a sparse compile cleanup of shub_mmr.h using both the defconfig and the sn2_defconfig config files. The issue with this file was the missing usage of __IA64_UL_CONST wrapper. This wrapper is defined in include/asm-ia64/types.h and wraps a long constant definition with UL or with nothing depending on its usage in the kernel. The missing wrapper caused many sparse compile errors like warning: constant 0x0x0000000010000380 so big it is long Signed-off-by: Prarit Bhargava <prarit@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

2005-04-25[IA64-SGI] Altix SN add support for slots in geoid_t locatorMark Goodwin
This patch against ia64-test-2.6.12 is needed for forthcoming Altix chipsets. It renames geoid_any_t to geoid_common_t and splits the 8bit 'slab' field into two 4bit fields for 'slab' and 'slot'. Similar changes in the Altix SAL will retain backward compatibility for old kernels. Signed-off-by: Mark Goodwin <markgw@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

2005-04-25[IA64-SGI] Altix: enable poweroffAaron J Young
This patch adds the necessary "hook" to allow SGI/SN machines to perform a system power off upon a 'init 0', 'halt -p', 'poweroff' or 'shutdown -h'. The "hook" is to set the pm_power_off callback to ia64_sn_power_down(). pm_power_off is checked in machine_power_off()/do_poweroff() and, if set, is executed. ia64_sn_power_down() is a function already present (but not used currently) in the sn kernel. ia64_sn_power_down() makes a SAL call to execute the power off.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
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!
