* [PATCH] kdump: read previous kernel's memoryVivek Goyal2006-01-106-27/+88
| | | | | | | | | | | | | | | | - Moving the crash_dump.c file to arch dependent part as kmap_atomic_pfn is specific to i386 and highmem may not exist in other archs. - Use ioremap for x86_64 to map the previous kernel memory. - In copy_oldmem_page(), we now directly copy to the user/kernel buffer and avoid the unneccesary copy to a kmalloc'd page.

* [PATCH] kdump: x86_64 save cpu registers upon crashVivek Goyal2006-01-103-0/+113
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Saving the cpu registers of all cpus before booting in to the crash kernel. - crash_setup_regs will save the registers of the cpu on which panic has occured. One of the concerns ppc64 folks raised is that after capturing the register states, one should not pop the current call frame and push new one. Hence it has been inlined. More call frames later get pushed on to stack (machine_crash_shutdown() and machine_kexec()), but one will not want to backtrace those. - Not very sure about the CFI annotations. With this patch I am getting decent backtrace with gdb. Assuming, compiler has generated enough debugging information for crash_kexec(). Coding crash_setup_regs() in pure assembly makes it tricky because then it can not be inlined and we don't want to return back after capturing register states we don't want to pop this call frame. - Saving the non-panicing cpus registers will be done in the NMI handler while shooting down them in machine_crash_shutdown. - Introducing CRASH_DUMP option in Kconfig for x86_64.

* [PATCH] kdump: save registers early (inline functions)Vivek Goyal2006-01-103-45/+51
| | | | | | | | | | | | | | | | | | | | | | | | | | - If system panics then cpu register states are captured through funciton crash_get_current_regs(). This is not a inline function hence a stack frame is pushed on to the stack and then cpu register state is captured. Later this frame is popped and new frames are pushed (machine_kexec). - In theory this is not very right as we are capturing register states for a frame and that frame is no more valid. This seems to have created back trace problems for ppc64. - This patch fixes it up. The very first thing it does after entering crash_kexec() is to capture the register states. Anyway we don't want the back trace beyond crash_kexec(). crash_get_current_regs() has been made inline - crash_setup_regs() is the top architecture dependent function which should be responsible for capturing the register states as well as to do some architecture dependent tricks. For ex. fixing up ss and esp for i386. crash_setup_regs() has also been made inline to ensure no new call frame is pushed onto stack.

| | | | | | | | | | | | | | | | - Kexec on panic functionality allocates memory for saving cpu registers in case of system crash event. Address of this allocated memory needs to be exported to user space, which is used by kexec-tools. - Previously, a single /sys/kernel/crash_notes entry was being exported as memory allocated was a single continuous array.

* [PATCH] kdump: dynamic per cpu allocation of memory for saving cpu registersVivek Goyal2006-01-1010-24/+21
| | | | | | | | | | | | | | | | | | | | | - In case of system crash, current state of cpu registers is saved in memory in elf note format. So far memory for storing elf notes was being allocated statically for NR_CPUS. - This patch introduces dynamic allocation of memory for storing elf notes. It uses alloc_percpu() interface. This should lead to better memory usage. - Introduced based on Andi Kleen's and Eric W. Biederman's suggestions. - This patch also moves memory allocation for elf notes from architecture dependent portion to architecture independent portion. Now crash_notes is architecture independent. The whole idea is that size of memory to be allocated per cpu (MAX_NOTE_BYTES) can be architecture dependent and allocation of this memory can be architecture independent.

| * [PATCH] PCI: use bus numbers sparsely, if necessaryDominik Brodowski2006-01-091-2/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | Add a warning if a child bus may be inaccessible because the parent bridge has wrong secondary or subordinate bus numbers. Note that this may or may not happen on "transparent" bridges, as can be seen in bug #5557. Also, if we do not fix up the assignment of bus numbers, try to make use of the bus number space available.

| * [PATCH] pciehp: handle sticky power-fault statusThomas Schaefer2006-01-091-2/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch disables power fault, MRL sensor and presence detection interrupts when a PCIe slot is powered-off and enables those interrupts when it is powered-on again. This is necessary to prevent the associated events from causing an endless cycle of interrupts due to the power-fault bit, which stays set till power is restored to the slot.

| * [PATCH] PCI Quirk: 1K I/O space granularity on Intel P64H2Daniel Yeisley2006-01-092-2/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | I've implemented a quirk to take advantage of the 1KB I/O space granularity option on the Intel P64H2 PCI Bridge. I had to change probe.c because it sets the resource start and end to be aligned on 4k boundaries (after the quirk sets them to 1k boundaries). I've tested this patch on a Unisys ES7000-600 both with and without the 1KB option enabled. I also tested this on a 2 processor Dell box that doesn't have a P64H2 to make sure there were no negative affects there.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The RPAPHP code contains two routines that appear to be gratuitous copies of very similar pci code. In particular, rpaphp_claim_resource ~~ pci_claim_resource (there is a minor, non-functional difference) rpadlpar_claim_one_bus == pcibios_claim_one_bus (the code is identical) This patch removes the rpaphp versions of the code.
