8 years agox86-64, xen, mmu: Provide an early version of write_cr3.
Konrad Rzeszutek Wilk [Sat, 23 Feb 2013 01:35:13 +0000 (17:35 -0800)]
x86-64, xen, mmu: Provide an early version of write_cr3.

With commit 8170e6bed465 ("x86, 64bit: Use a #PF handler to materialize
early mappings on demand") we started hitting an early bootup crash
where the Xen hypervisor would inform us that:

    (XEN) d7:v0: unhandled page fault (ec=0000)
    (XEN) Pagetable walk from ffffea000005b2d0:
    (XEN)  L4[0x1d4] = 0000000000000000 ffffffffffffffff
    (XEN) domain_crash_sync called from entry.S
    (XEN) Domain 7 (vcpu#0) crashed on cpu#3:
    (XEN) ----[ Xen-4.2.0  x86_64  debug=n  Not tainted ]----

.. that Xen was unable to context switch back to dom0.

Looking at the calling stack we find:

    [<ffffffff8103feba>] xen_get_user_pgd+0x5a  <--
    [<ffffffff8103feba>] xen_get_user_pgd+0x5a
    [<ffffffff81042d27>] xen_write_cr3+0x77
    [<ffffffff81ad2d21>] init_mem_mapping+0x1f9
    [<ffffffff81ac293f>] setup_arch+0x742
    [<ffffffff81666d71>] printk+0x48

We are trying to figure out whether we need to up-date the user PGD as
well.  Please keep in mind that under 64-bit PV guests we have a limited
amount of rings: 0 for the Hypervisor, and 1 for both the Linux kernel
and user-space.  As such the Linux pvops'fied version of write_cr3
checks if it has to update the user-space cr3 as well.

That clearly is not needed during early bootup.  The recent changes (see
above git commit) streamline the x86 page table allocation to be much
simpler (And also incidentally the #PF handler ends up in spirit being
similar to how the Xen toolstack sets up the initial page-tables).

The fix is to have an early-bootup version of cr3 that just loads the
kernel %cr3.  The later version - which also handles user-page
modifications will be used after the initial page tables have been
setup.

[ hpa: removed a redundant #ifdef and made the new function __init.
  Also note that x86-32 already has such an early xen_write_cr3. ]

Linus Torvalds [Fri, 22 Feb 2013 21:09:51 +0000 (13:09 -0800)]
x86-64: don't set the early IDT to point directly to 'early_idt_handler'

 "This is a huge set of several partly interrelated (and concurrently
  developed) changes, which is why the branch history is messier than
  one would like.

  The *really* big items are two humonguous patchsets mostly developed
  by Yinghai Lu at my request, which completely revamps the way we
  create initial page tables.  In particular, rather than estimating how
  much memory we will need for page tables and then build them into that
  memory -- a calculation that has shown to be incredibly fragile -- we
  now build them (on 64 bits) with the aid of a "pseudo-linear mode" --
  a #PF handler which creates temporary page tables on demand.

  This has several advantages:

  1. It makes it much easier to support things that need access to data
     very early (a followon patchset uses this to load microcode way
     early in the kernel startup).

  2. It allows the kernel and all the kernel data objects to be invoked
     from above the 4 GB limit.  This allows kdump to work on very large
     systems.

  3. It greatly reduces the difference between Xen and native (Xen's
     equivalent of the #PF handler are the temporary page tables created
     by the domain builder), eliminating a bunch of fragile hooks.

  The patch series also gets us a bit closer to W^X.

  Additional work in this pull is the 64-bit get_user() work which you
  were also involved with, and a bunch of cleanups/speedups to
  __phys_addr()/__pa()."

drivers/rtc/rtc-tps65910.c: set irq flag to IRQF_EARLY_RESUME during irq request

All interrupt get disabled during system suspend and enabled during system
resume.  The enabling/disabling of interrupt happen in sequence of
interrupt registration with framework.

Therefore, in resume, the parent interrupt of this device enabled before
the RTC irq interrupt enabled.  If RTC is enabled for alarm wake and if
system wake by alarm then there is interrupt pending for RTC.  In resume,
the parent interrupt get enabled before the rtc interrupt and hence ISR
get served.  In ISR, it founds that rtc interrupt is disabled and so it
does not call the rtc isr handler and hence it misses the interrupt.

Setting flag for early resume so that rtc interrupt get enabled before
parent interrupt and so rtc interrupt get enabled when parent interrupt
handler check for interrupt of device and call the rtc handler if it is
there.  This way it will not miss the interrupt.

 Change on device initialization
 ===============================

 - Just update the brightness/device control register/ROM area(optional).
 In new LP855x driver architecture, two more works are added - pre_init and
 post_init.
 Those init functions are optional, used for new device LP8557.

 2) update the brightness register
 3) update the device control register
 4) update ROM area if need
 5) post_init_device()

8 years agobacklight: add an AS3711 PMIC backlight driver

backlight: add an AS3711 PMIC backlight driver

This is an initial commit of a backlight driver, using step-up DCDC
power supplies on AS3711 PMIC.  Only one mode has actually been tested,
several further modes have been implemented "dry," but disabled to avoid
accidental hardware damage.  Anyone wishing to use any of those modes
will have to modify the driver.

Tested on sh73a0-based kzm9g board.  Only one mode has been tested and
is enabled.  That mode copies the sample code from the manufacturer.
Deviations from that code proved to be fatal for the hardware...
