2011-12-21perf events: Add Intel x86 mapping for PERF_COUNT_HW_REF_CPU_CYCLESStephane Eranian
Add event maps for Intel x86 processors (with architected PMU v2 or later). On AMD, there is frequency scaling but no Turbo. There is no core cycle event not subject to frequency scaling, therefore we do not provide a mapping.

2011-12-15xen: only limit memory map to maximum reservation for domain 0.Ian Campbell
d312ae878b6a "xen: use maximum reservation to limit amount of usable RAM" clamped the total amount of RAM to the current maximum reservation. This is correct for dom0 but is not correct for guest domains. In order to boot a guest "pre-ballooned" (e.g. with memory=1G but maxmem=2G) in order to allow for future memory expansion the guest must derive max_pfn from the e820 provided by the toolstack and not the current maximum reservation (which can reflect only the current maximum, not the guest lifetime max). The existing algorithm already behaves this correctly if we do not artificially limit the maximum number of pages for the guest case. For a guest booted with maxmem=512, memory=128 this results in: [ 0.000000] BIOS-provided physical RAM map: [ 0.000000] Xen: 0000000000000000 - 00000000000a0000 (usable) [ 0.000000] Xen: 00000000000a0000 - 0000000000100000 (reserved) -[ 0.000000] Xen: 0000000000100000 - 0000000008100000 (usable) -[ 0.000000] Xen: 0000000008100000 - 0000000020800000 (unusable) +[ 0.000000] Xen: 0000000000100000 - 0000000020800000 (usable) ...

2011-12-09x86, efi: Make efi_call_phys_{prelog,epilog} CONFIG_RELOCATABLE-awareMatt Fleming
efi_call_phys_prelog() sets up a 1:1 mapping of the physical address range in swapper_pg_dir. Instead of replacing then restoring entries in swapper_pg_dir we should be using initial_page_table which already contains the 1:1 mapping. It's safe to blindly switch back to swapper_pg_dir in the epilog because the physical EFI routines are only called before efi_enter_virtual_mode(), e.g. before any user processes have been forked. Therefore, we don't need to track which pgd was in %cr3 when we entered the prelog. The previous code actually contained a bug because it assumed that the kernel was loaded at a physical address within the first 8MB of ram, usually at 0x100000. However, this isn't the case with a CONFIG_RELOCATABLE=y kernel which could have been loaded anywhere in the physical address space. Also delete the ancient (and bogus) comments about the page table being restored after the lock is released. There is no locking.

2011-12-09thp: add compound tail page _mapcount when mappedYouquan Song
With the 3.2-rc kernel, IOMMU 2M pages in KVM works. But when I tried to use IOMMU 1GB pages in KVM, I encountered an oops and the 1GB page failed to be used. The root cause is that 1GB page allocation calls gup_huge_pud() while 2M page calls gup_huge_pmd. If compound pages are used and the page is a tail page, gup_huge_pmd() increases _mapcount to record tail page are mapped while gup_huge_pud does not do that. So when the mapped page is relesed, it will result in kernel oops because the page is not marked mapped. This patch add tail process for compound page in 1GB huge page which keeps the same process as 2M page. Reproduce like: 1. Add grub boot option: hugepagesz=1G hugepages=8 2. mount -t hugetlbfs -o pagesize=1G hugetlbfs /dev/hugepages 3. qemu-kvm -m 2048 -hda os-kvm.img -cpu kvm64 -smp 4 -mem-path /dev/hugepages -net none -device pci-assign,host=07:00.1 kernel BUG at mm/swap.c:114! invalid opcode: 0000 [#1] SMP Call Trace: put_page+0x15/0x37 kvm_release_pfn_clean+0x31/0x36 kvm_iommu_put_pages+0x94/0xb1 kvm_iommu_unmap_memslots+0x80/0xb6 kvm_assign_device+0xba/0x117 kvm_vm_ioctl_assigned_device+0x301/0xa47 kvm_vm_ioctl+0x36c/0x3a2 do_vfs_ioctl+0x49e/0x4e4 sys_ioctl+0x5a/0x7c system_call_fastpath+0x16/0x1b RIP put_compound_page+0xd4/0x168 Signed-off-by: Youquan Song <youquan.song@intel.com> Reviewed-by: Andrea Arcangeli <aarcange@redhat.com> Cc: Andi Kleen <andi@firstfloor.org> Cc: <stable@vger.kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2011-12-09x86, efi: Calling __pa() with an ioremap()ed address is invalidMatt Fleming
If we encounter an efi_memory_desc_t without EFI_MEMORY_WB set in ->attribute we currently call set_memory_uc(), which in turn calls __pa() on a potentially ioremap'd address. On CONFIG_X86_32 this is invalid, resulting in the following oops on some machines: BUG: unable to handle kernel paging request at f7f22280 IP: [<c10257b9>] reserve_ram_pages_type+0x89/0x210 [...] Call Trace: [<c104f8ca>] ? page_is_ram+0x1a/0x40 [<c1025aff>] reserve_memtype+0xdf/0x2f0 [<c1024dc9>] set_memory_uc+0x49/0xa0 [<c19334d0>] efi_enter_virtual_mode+0x1c2/0x3aa [<c19216d4>] start_kernel+0x291/0x2f2 [<c19211c7>] ? loglevel+0x1b/0x1b [<c19210bf>] i386_start_kernel+0xbf/0xc8 A better approach to this problem is to map the memory region with the correct attributes from the start, instead of modifying it after the fact. The uncached case can be handled by ioremap_nocache() and the cached by ioremap_cache(). Despite first impressions, it's not possible to use ioremap_cache() to map all cached memory regions on CONFIG_X86_64 because EFI_RUNTIME_SERVICES_DATA regions really don't like being mapped into the vmalloc space, as detailed in the following bug report, https://bugzilla.redhat.com/show_bug.cgi?id=748516 Therefore, we need to ensure that any EFI_RUNTIME_SERVICES_DATA regions are covered by the direct kernel mapping table on CONFIG_X86_64. To accomplish this we now map E820_RESERVED_EFI regions via the direct kernel mapping with the initial call to init_memory_mapping() in setup_arch(), whereas previously these regions wouldn't be mapped if they were after the last E820_RAM region until efi_ioremap() was called. Doing it this way allows us to delete efi_ioremap() completely. Signed-off-by: Matt Fleming <matt.fleming@intel.com> Cc: H.

2011-12-08x86, hpet: Immediately disable HPET timer 1 if rtc irq is maskedMark Langsdorf
When HPET is operating in RTC mode, the TN_ENABLE bit on timer1 controls whether the HPET or the RTC delivers interrupts to irq8. When the system goes into suspend, the RTC driver sends a signal to the HPET driver so that the HPET releases control of irq8, allowing the RTC to wake the system from suspend. The switchover is accomplished by a write to the HPET configuration registers which currently only occurs while servicing the HPET interrupt. On some systems, I have seen the system suspend before an HPET interrupt occurs, preventing the write to the HPET configuration register and leaving the HPET in control of the irq8. As the HPET is not active during suspend, it does not generate a wake signal and RTC alarms do not work. This patch forces the HPET driver to immediately transfer control of the irq8 channel to the RTC instead of waiting until the next interrupt event.

2011-12-08ARM: S5PV210: Set 1000ns as PWM backlight period on SMDKV210Jingoo Han
The SMDK board uses LT3591 as backlight LED driver of LTE480WV LCD. According to the LT3591 datasheet, the switching frequency should be 1MHz. So, PWM period is calculated by following formula: PWM period = 1/switching frequency = 1/1MHz = 1000ns Thus, the PWM backlight period should be 1000ns.

2011-12-07oprofile, s390: Add event interface to the System z hardware sampling moduleAndreas Krebbel
With this patch the OProfile Basic Mode Sampling support for System z is enhanced with a counter file system. That way hardware sampling can be configured using the user space tools with only little modifications. With the patch by default new cpu_types (s390/z10, s390/z196) are returned in order to indicate that we are running a CPU which provides the hardware sampling facility. Existing user space tools will complain about an unknown cpu type. In order to be compatible with existing user space tools the `cpu_type' module parameter has been added. Setting the parameter to `timer' will force the module to return `timer' as cpu_type. The module will still try to use hardware sampling if available and the hwsampling virtual filesystem will be also be available for configuration. So this has a different effect than using the generic oprofile module parameter `timer=1'. If the basic mode sampling is enabled on the machine and the cpu_type=timer parameter is not used the kernel module will provide the following virtual filesystem: /dev/oprofile/0/enabled /dev/oprofile/0/event /dev/oprofile/0/count /dev/oprofile/0/unit_mask /dev/oprofile/0/kernel /dev/oprofile/0/user In the counter file system only the values of 'enabled', 'count', 'kernel', and 'user' are evaluated by the kernel module. Everything else must contain fixed values. The 'event' value only supports a single event - HWSAMPLING with value 0. The 'count' value specifies the hardware sampling rate as it is passed to the CPU measurement facility. The 'kernel' and 'user' flags can now be used to filter for samples when using hardware sampling. Additionally also the following file will be created: /dev/oprofile/timer/enabled This will always be the inverted value of /dev/oprofile/0/enabled. 0 is not accepted without hardware sampling.

2011-12-06perf, x86: Implement arch event mask as quirkPeter Zijlstra
Implement the disabling of arch events as a quirk so that we can print a message along with it. This creates some visibility into the problem space and could allow us to work on adding more work-around like the AAJ80 one.
