* [PATCH kernel v2 REPOST] powerpc/powernv/ioda: Allocate indirect TCE levels on demand

In-Reply-To: <20180621020321.GE32328@umbus.fritz.box>
At the moment we allocate the entire TCE table, twice (hardware part and
userspace translation cache). This normally works as we normally have
contigous memory and the guest will map entire RAM for 64bit DMA.
However if we have sparse RAM (one example is a memory device), then
we will allocate TCEs which will never be used as the guest only maps
actual memory for DMA. If it is a single level TCE table, there is nothing
we can really do but if it a multilevel table, we can skip allocating
TCEs we know we won't need.
This adds ability to allocate only first level, saving memory.
This changes iommu_table::free() to avoid allocating of an extra level;
iommu_table::set() will do this when needed.
This adds @alloc parameter to iommu_table::exchange() to tell the callback
if it can allocate an extra level; the flag is set to "false" for
the realmode KVM handlers of H_PUT_TCE hcalls and the callback returns
H_TOO_HARD.
This still requires the entire table to be counted in mm::locked_vm.
To be conservative, this only does on-demand allocation when
the usespace cache table is requested which is the case of VFIO.
The example math for a system replicating a powernv setup with NVLink2
in a guest:
16GB RAM mapped at 0x0
128GB GPU RAM window (16GB of actual RAM) mapped at 0x244000000000
the table to cover that all with 64K pages takes:
(((0x244000000000 + 0x2000000000) >> 16)*8)>>20 = 4556MB
If we allocate only necessary TCE levels, we will only need:
(((0x400000000 + 0x400000000) >> 16)*8)>>20 = 4MB (plus some for indirect
levels).

This is what I meant to post few days ago, sorry for the noise.

Changes:
v2:
* fixed bug in cleanup path which forced the entire table to be
allocated right before destroying
* added memory allocation error handling pnv_tce()

Yeah OK. We don't have a good way to express that, other than using a
merge which I'd prefer to avoid.
So I've tagged them all with your Tested-by. If any of them turn out to
have bugs you can blame me :)

i40e: use WARN_ONCE to replace the commented BUG_ON size check
We don't really want to use BUG_ON here since that would completely
crash the kernel, thus the reason we commented it out. We *can't* use
BUILD_BUG_ON because at least now (a) the sizes aren't constant (we are
fixing this) and (b) not all compilers are smart enough to understand
that "p - data" is a constant.

I don't have that commit ^ ?
That might be because I squashed some of your fixes together or something?

I think you need Acks from Robin and Joerg in order for this to be queued.
Robin should be back at the beginning of next month, so there's still time
for 4.19.

That will impact config with VMEMMAP_EXTREME with no real immediate
benefit. We could possibly make MAX_PHYSMEM_BITS a Kconfig variable.
s390 do that. Not sure we want to do that.

right. Child processes will see stale value of AMR. Technically this
behavior is a bug, since existing applications; if any, cannot rely on
this stale AMR value.

I just tested the patches incrementally using the pkey selftests.
So I feel confident these patches are not bugs. I will take the blame

ida_alloc_range is the perfect fit for this use case. Eliminates
a custom spinlock, a call to ida_pre_get and a local check for the
allocated ID exceeding a maximum.

Silently using the wrong data is a worse habit than not checking for

The full function is:
static void unmap_cpu_from_node(unsigned long cpu)
{
int node = numa_cpu_lookup_table[cpu];
dbg("removing cpu %lu from node %d\n", cpu, node);
if (cpumask_test_cpu(cpu, node_to_cpumask_map[node])) {
cpumask_clear_cpu(cpu, node_to_cpumask_map[node]);
} else {
printk(KERN_ERR "WARNING: cpu %lu not found in node %d\n",
cpu, node);
}
}
So we look up what node the CPU is on, and then we lookup the set of
CPUs on that node, and they don't match.
That seems like a bug, not a warning.
Have you looked at why we're seeing this warning? It seems like maybe
something else is going wrong to get us into this situation to begin
with.
If there's some good reason why this is happening, and it's truly
harmless, then we can just remove the printk() entirely.

This hunk should be okay because the mmu_context_lock does not protect
the extended_id array, right Aneesh?

That's my understanding. The code today does this:
static inline int alloc_extended_context(struct mm_struct *mm,
unsigned long ea)
{
int context_id;
int index = ea >> MAX_EA_BITS_PER_CONTEXT;
context_id = hash__alloc_context_id();
if (context_id < 0)
return context_id;
VM_WARN_ON(mm->context.extended_id[index]);
mm->context.extended_id[index] = context_id;
so it's not currently protected by this lock. I suppose we are currently
protected from destroy_contexts() being called twice simultaneously, but
you'll notice that we don't zero the array elements in destroy_contexts(),
so if we somehow had a code path which could call it concurrently, we'd
be seeing warnings when the second caller tried to remove the context
IDs from the IDA. I deduced that something else must be preventing
this situation from occurring (like, oh i don't know, this function only
being called on process exit, so implicitly only called once per context).

Yeah that'd be an existing bug.

I think that's exactly right.

I really don't like the WARN_ON(), but I'd prefer to address that in a
separate patch rather than impede the progress of this patch (or of this
series, since 3/3 seems to be unrelated).
BTW, have you considered using the same wrap-around test (i.e. YY < 70)
that we use for the year register in the other RTC chips?

Your recent patches to the Mac RTC routines (which are duplicated under
arch/m68k and arch/powerpc) conflict with my recent patch that
deduplicates the same code. So I will rebase and resubmit after someone
merges these fixes.
Apparently the PowerMac routines work now, which is sufficient testing for
me; the PowerMac routines will get tested on m68k Macs when that code gets
deduplicated again.
BTW, Joshua tells me that he is not doing code review. We should probably
drop the "M68K ON APPLE MACINTOSH" entry from the MAINTAINERS file, like
the Amiga and Atari ports...
