* ARM: tegra: add LP1 support code for Tegra124Joseph Lo2013-10-185-8/+43
| | | | | | | | | The LP1 suspend procedure is the same with Tegra30 and Tegra114. Just need to update the difference of the register address, then we can continue to share the code. Signed-off-by: Joseph Lo <josephl@nvidia.com> Signed-off-by: Stephen Warren <swarren@nvidia.com>
* ARM: tegra: re-calculate the LP1 data for Tegra30/114Joseph Lo2013-10-181-7/+9
| | | | | | | | | | | This patch re-calculates the LP1 data of tegra30/114_sdram_pad_address to base on its label not rely on others. This can make easier to maintain if some other Tegra chips keep re-using these codes in the future. And change the name of tegra30_sdram_pad_save to tegra_sdram_pad_save to make it more common to other chips.

* ARM: tegra: make tegra_resume can work with current and later chipsJoseph Lo2013-10-181-8/+5
| | | | | | | | | | | Because the CPU0 was the first up and the last down core when cluster power up/down or platform suspend. So only CPU0 needs the rest of the functions to reset flow controller and re-enable SCU and L2. We also move the L2 init function for Cortex-A15 to there. The secondery CPU can just call cpu_resume.

| | | | | | | | | common.c was create to contain code shared across the various Tegra board files. There is now only one board file, tegra.c. So, move the code there.

* ARM: tegra: split tegra_pmc_init() in twoStephen Warren2013-09-174-23/+35
| | | | | | | | | | | | | | | | | | | | | | | | | Tegra's board file currently initializes clocks much earlier than those for most other ARM SoCs. The reason is: * The PMC HW block is involved in the path of some interrupts (i.e. it inverts, or not, the IRQ input pin dedicated to the PMIC). * So, that part of the PMC must be initialized early so that the IRQ polarity is correct. * The PMC initialization is currently monolithic, and the PMC has some clock inputs, so the init routine ends up calling of_clk_get_by_name(), and hence clocks must be set up early too. In order to defer clock initialization to the more typical location, split out the portions of tegra_pmc_init() that are truly IRQ-related into a separate tegra_pmc_init_irq(), which can be called from the machine descriptor's .init_irq() function, and defer the rest until the machine descriptor's .init_machine() function. This allows the clock initiliazation to happen from the machine descriptor's .init_time() function, as is typical. Signed-off-by: Stephen Warren <swarren@nvidia.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a cpu goes to a deep idle state where its local timer is shutdown, it notifies the time frame work to use the broadcast timer instead. Unfortunately, the broadcast device could wake up any CPU, including an idle one which is not concerned by the wake up at all. This implies, in the worst case, an idle CPU will wake up to send an IPI to another idle cpu. This patch fixes this for ARM platforms using timer-sp, by setting CLOCK_EVT_FEAT_DYNIRQ feature.

(2) The code was confused between the PCI I/O window (at 0x43000000) and the first PCI memory window (at 0x44000000), which meant that PCI devices using PCI PIO rather than MMIO didn't work. This is fixed (and some variables/labels are renamed to avoid further confusion in future). (3) The SMAP register offsets were all off-by-four, though by fluke this didn't actually have any ill effects. All these changes have been tested on real hardware (PB926 plus the PCI backplane), as well as on QEMU. I have confirmed that IRQs and PCI PIO and MMIO work OK. PCI bus-master DMA doesn't seem to work on h/w -- as far as I can tell the device is correctly managing to DMA to the right places in memory, but every other 32 bit word is corrupt (at least judging from rtl8139 debug dumps of the frames it's receiving). I'm not sure what's going on here, but since this is disjoint from the irq and I/O issues I don't think that applying the patches that fix those should be stalled on trying to debug DMA problems. (DMA works fine on QEMU, incidentally.) * versatile/fixes: ARM: PCI: versatile: Fix SMAP register offsets ARM: PCI: versatile: Fix PCI I/O ARM: PCI: versatile: Fix map_irq function to match hardware Signed-off-by: Olof Johansson <olof@lixom.net>

Since the first PCI memory window isn't used at all (it's an odd size), rename the associated variables and labels so that it's clear that it isn't related to the I/O window.

For many years it had an odd mapping ("all interrupts are int 27") which aligned with the equivalent bug in QEMU. However as of commit 1bc39ac5dab265 the mapping changed and no longer matched either hardware or QEMU, with the result that any PCI card beyond the first in QEMU would not have functioning interrupts; for example a boot with a SCSI controller would time out as follows: ------------ sym0: <895a> rev 0x0 at pci 0000:00:0d.0 irq 92 sym0: SCSI BUS has been reset. scsi0 : sym-2.2.3 [...] scsi 0:0:0:0: ABORT operation started scsi 0:0:0:0: ABORT operation timed-out. scsi 0:0:0:0: DEVICE RESET operation started scsi 0:0:0:0: DEVICE RESET operation timed-out. scsi 0:0:0:0: BUS RESET operation started scsi 0:0:0:0: BUS RESET operation timed-out. scsi 0:0:0:0: HOST RESET operation started sym0: SCSI BUS has been reset ------------ Fix the mapping so that it matches real hardware (checked against the schematics for PB926 and backplane, and tested against the hardware). This allows PCI cards using interrupts to work on hardware for the first time; this change will also work with QEMU 1.5 or later, where the equivalent bugs in the modelling of the hardware have been fixed. Although QEMU will attempt to autodetect whether the kernel is expecting the long-standing "everything is int 27" mapping or the one hardware has, for certainty we force it into "definitely behave like hardware mode"; this will avoid unexpected surprises later if we implement sparse irqs.

This is problematic on marzen with Magnus's recent patch "ARM: shmobile: marzen: Switch to DT_MACHINE_START" which switches marzen around to enable USE_OF and thus shmobile_timer_init(), which is registered as late_time_init by shmobile_earlytimer_init() stops being a no-op. As a work-around I have updated r8a7779_earlytimer_init() so that shmobile_earlytimer_init() is called after r8a7779_register_twd(). Or in other words, the shmobile_earlytimer_init() setting of late_time_init overwrites that of twd_local_timer_common_register().

Some users of hugepage migration (mbind, move_pages, and migrate_pages) do page table walk and check pud/pmd_huge() there, so they are safe. But the other users (softoffline and memory hotremove) don't do this, so without this patch they can try to migrate unexpected types of hugepages. To prevent this, we introduce hugepage_migration_support() as an architecture dependent check of whether hugepage are implemented on a pmd basis or not. And on some architecture multiple sizes of hugepages are available, so hugepage_migration_support() also checks hugepage size.

The simple ones are the ARM ones - one of the patches fell through the cracks, other fixes a bootup issue (unconditionally using Xen functions). Then a fix for a regression causing preempt count being off (patch causing this went in v3.12). Lastly are the fixes to make Xen PVHVM guests use PV ticketlocks (Xen PV already does). The enablement of that was supposed to be part of the x86 spinlock merge in commit 816434ec4a67 ("The biggest change here are paravirtualized ticket spinlocks (PV spinlocks), which bring a nice speedup on various benchmarks...") but unfortunatly it would cause hang when booting Xen PVHVM guests. Yours truly got all of the bugs fixed last week and they (six of them) are included in this pull. Bug-fixes: - Boot on ARM without using Xen unconditionally - On Xen ARM don't run cpuidle/cpufreq - Fix regression in balloon driver, preempt count warnings - Fixes to make PVHVM able to use pv ticketlock. - Revert Xen PVHVM disabling pv ticketlock (aka, re-enable pv ticketlocks)" * tag 'stable/for-linus-3.12-rc0-tag-two' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip: xen/spinlock: Don't use __initdate for xen_pv_spin Revert "xen/spinlock: Disable IRQ spinlock (PV) allocation on PVHVM" xen/spinlock: Don't setup xen spinlock IPI kicker if disabled. xen/smp: Update pv_lock_ops functions before alternative code starts under PVHVM xen/spinlock: We don't need the old structure anymore xen/spinlock: Fix locking path engaging too soon under PVHVM. xen/arm: disable cpuidle and cpufreq when linux is running as dom0 xen/p2m: Don't call get_balloon_scratch_page() twice, keep interrupts disabled for multicalls ARM: xen: only set pm function ptrs for Xen guests
