2008-12-29x86, pci: move arch/x86/pci/pci.h to arch/x86/include/asm/pci_x86.hJaswinder Singh Rajput1-1/+1
Impact: cleanup Now that arch/x86/pci/pci.h is used in a number of other places as well, move the lowlevel x86 pci definitions into the architecture include files. (not to be confused with the existing arch/x86/include/asm/pci.h file, which provides public details about x86 PCI) Tested on: X86_32_UP, X86_32_SMP and X86_64_SMP Signed-off-by: Jaswinder Singh Rajput <jaswinderrajput@gmail.com> Acked-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-08-23x86: fix: make PCI ECS for AMD CPUs hotplug capableRobert Richter1-4/+31
Until now, PCI ECS setup was performed at boot time only and for cpus that are enabled then. This patch fixes this and adds cpu hotplug. Tests sequence (check if ECS bit is set when bringing cpu online again): # ( perl -e 'sysseek(STDIN, 0xC001001F, 0)'; hexdump -n 8 -e '2/4 "%08x " "\n"' ) < /dev/cpu/1/msr 00000008 00404010 # ( perl -e 'sysseek(STDOUT, 0xC001001F, 0); print pack "l*", 8, 0x00400010' ) > /dev/cpu/1/msr # ( perl -e 'sysseek(STDIN, 0xC001001F, 0)'; hexdump -n 8 -e '2/4 "%08x " "\n"' ) < /dev/cpu/1/msr 00000008 00400010 # echo 0 > /sys/devices/system/cpu/cpu1/online # echo 1 > /sys/devices/system/cpu/cpu1/online # ( perl -e 'sysseek(STDIN, 0xC001001F, 0)'; hexdump -n 8 -e '2/4 "%08x " "\n"' ) < /dev/cpu/1/msr 00000008 00404010 Reported-by: Yinghai Lu <yhlu.kernel@gmail.com> Signed-off-by: Robert Richter <robert.richter@amd.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
