5 years agomips: Remove q-accessors from non-64bit platforms
Serge Semin [Fri, 14 Jun 2019 06:33:42 +0000 (09:33 +0300)]
mips: Remove q-accessors from non-64bit platforms

There are some generic drivers in the kernel, which make use of the
q-accessors or their derivatives. While at current asm/io.h the accessors
are defined, their implementation is only applicable either for 64bit
systems, or for systems with cpu_has_64bits flag set. Obviously there
are MIPS systems which are neither of these, but still need to have
those drivers supported. In this case the solution is to define some
generic versions of the q-accessors, but with a limitation to be
non-atomic. Such accessors are defined in the
io-64-nonatomic-{hi-lo,lo-hi}.h file. The drivers which utilize the
q-suffixed IO-methods are supposed to include the header file, so
in case if these accessors aren't defined for the platform, the generic
non-atomic versions are utilized. Currently the MIPS-specific asm/io.h
file provides the q-accessors for any MIPS system even for ones, which
in fact don't support them and raise BUG() in case if any of them is
called. Due to this the generic versions of the accessors are never
used while an attempt to call the IO-methods causes the kernel BUG().
In order to fix this we need to define the q-accessors only for
the MIPS systems, which actually support them, and don't define them
otherwise, so to let the corresponding drivers to use the non-atomic
q-suffixed accessors.

FDDI: defza: Include linux/io-64-nonatomic-lo-hi.h

Currently arch/mips/include/asm/io.h provides 64b memory accessor
functions such as readq & writeq even on MIPS32 platforms where those
accessors cannot actually perform a 64b memory access. They instead
BUG(). This is unfortunate for drivers which either #ifdef on the
presence of these accessors, or can function with non-atomic
implementations of them found in either linux/io-64-nonatomic-lo-hi.h or
linux/io-64-nonatomic-hi-lo.h. As such we're preparing to remove the
definitions of these 64b accessor functions for MIPS32 kernels.

In preparation for this, include linux/io-64-nonatomic-lo-hi.h in
defza.c in order to provide a non-atomic implementation of the
readq_relaxed & writeq_relaxed functions that are used by this code. In
practice this will have no runtime effect, since use of the 64b accessor
functions is conditional upon sizeof(unsigned long) == 8, ie. upon
CONFIG_64BIT=y. This means the calls to these non-atomic readq & writeq
implementations will be optimized out anyway, but we need their
definitions to keep the compiler happy.

For 64bit kernels using this code this change should also have no effect
because asm/io.h will continue to provide the definitions of
readq_relaxed & writeq_relaxed, which linux/io-64-nonatomic-lo-hi.h
checks for before defining itself.

The imprecise nature of the locking counts are also documented with

tools/kvm_stat: fix fields filter for child events

The fields filter would not work with child fields, as the respective
parents would not be included. No parents displayed == no childs displayed.
To reproduce, run on s390 (would work on other platforms, too, but would
require a different filter name):
- Run 'kvm_stat -d'
- Press 'f'
- Enter 'instruct'
Notice that events like instruction_diag_44 or instruction_diag_500 are not
displayed - the output remains empty.
With this patch, we will filter by matching events and their parents.
However, consider the following example where we filter by
instruction_diag_44:

  kvm statistics - summary
                   regex filter: instruction_diag_44
   Event                                         Total %Total CurAvg/s
   exit_instruction                                276  100.0       12
     instruction_diag_44                           256   92.8       11
   Total                                           276              12

Note that the parent ('exit_instruction') displays the total events, but
the childs listed do not match its total (256 instead of 276). This is
intended (since we're filtering all but one child), but might be confusing
on first sight.

5 years agokvm: Check irqchip mode before assign irqfd
Peter Xu [Sun, 5 May 2019 08:56:42 +0000 (16:56 +0800)]
kvm: Check irqchip mode before assign irqfd

When assigning kvm irqfd we didn't check the irqchip mode but we allow
KVM_IRQFD to succeed with all the irqchip modes.  However it does not
make much sense to create irqfd even without the kernel chips.  Let's
provide a arch-dependent helper to check whether a specific irqfd is
allowed by the arch.  At least for x86, it should make sense to check:

- when irqchip mode is NONE, all irqfds should be disallowed, and,

- when irqchip mode is SPLIT, irqfds that are with resamplefd should
  be disallowed.

For either of the case, previously we'll silently ignore the irq or
the irq ack event if the irqchip mode is incorrect.  However that can
cause misterious guest behaviors and it can be hard to triage.  Let's
fail KVM_IRQFD even earlier to detect these incorrect configurations.
