[v3,1/6] x86/MCE: Make struct mce_banks[] static

[Yazen Ghannam]

From: Yazen Ghannam <yazen.ghannam@amd.com>

The struct mce_banks[] array is only used in mce/core.c so move the
definition of struct mce_bank to mce/core.c and make the array static.

Also, change the "init" field to bool type.

[PATCH v3 0/6] Handle MCA banks in a per_cpu way

[Ghannam, Yazen]

From: Yazen Ghannam <yazen.ghannam@amd.com>

The focus of this patchset is define and use the MCA bank structures
and bank count per logical CPU.

With the exception of patch 4, this set applies to systems in production
today.

Patch 1:
Moves the declaration of struct mce_banks[] to the only file it's used.

Patch 2:
Splits struct mce_bank into a structure for fields common to MCA banks
on all CPUs and another structure that can be used per_cpu.

Patch 3:
Brings full circle the saga of the threshold block addresses on SMCA
systems. After taking a step back and reviewing the AMD documentation, I
think that this implimentation is the simplest and more robust way to
follow the spec.

Patch 4:
Saves and uses the MCA bank count as a per_cpu variable. This is to
support systems that have MCA bank counts that are different between
logical CPUs.

Patch 5:
Makes sure that sysfs reports the MCA_CTL value as set in hardware. This
is not something related to making things per_cpu but rather just
something I noticed while working on the other patches.

Patch 6:
Prevents sysfs access for MCA banks that are uninitialized.

[v3,2/6] x86/MCE: Handle MCA controls in a per_cpu way

[Yazen Ghannam]

From: Yazen Ghannam <yazen.ghannam@amd.com>

Current AMD systems have unique MCA banks per logical CPU even though
the type of the banks may all align to the same bank number. Each CPU
will have control of a set of MCA banks in the hardware and these are
not shared with other CPUs.

For example, bank 0 may be the Load-Store Unit on every logical CPU, but
each bank 0 is a unique structure in the hardware. In other words, there
isn't a *single* Load-Store Unit at MCA bank 0 that all logical CPUs
share.

This idea extends even to non-core MCA banks. For example, CPU0 and CPU4
may see a Unified Memory Controller at bank 15, but each CPU is actually
seeing a unique hardware structure that is not shared with other CPUs.

Because the MCA banks are all unique hardware structures, it would be
good to control them in a more granular way. For example, if there is a
known issue with the Floating Point Unit on CPU5 and a user wishes to
disable an error type on the Floating Point Unit, then it would be good
to do this only for CPU5 rather than all CPUs.

Also, future AMD systems may have heterogeneous MCA banks. Meaning the
bank numbers may not necessarily represent the same types between CPUs.
For example, bank 20 visible to CPU0 may be a Unified Memory Controller
and bank 20 visible to CPU4 may be a Coherent Slave. So granular control
will be even more necessary should the user wish to control specific MCA
banks.

Split the device attributes from struct mce_bank leaving only the MCA
bank control fields.

Make struct mce_banks[] per_cpu in order to have more granular control
over individual MCA banks in the hardware.

Allocate the device attributes statically based on the maximum number of
MCA banks supported. The sysfs interface will use as many as needed per
CPU. Currently, this is set to mca_cfg.banks, but will be changed to a
per_cpu bank count in a future patch.

Allocate the MCA control bits dynamically. Use the maximum number of MCA
banks supported for now. This will be changed to a per_cpu bank count in
a future patch.

Redo the sysfs store/show functions to handle the per_cpu mce_banks[].

[v3,3/6] x86/MCE/AMD: Don't cache block addresses on SMCA systems

[Yazen Ghannam]

From: Yazen Ghannam <yazen.ghannam@amd.com>

On legacy systems, the addresses of the MCA_MISC* registers need to be
recursively discovered based on a Block Pointer field in the registers.

On Scalable MCA systems, the register space is fixed, and particular
addresses can be derived by regular offsets for bank and register type.
This fixed address space includes the MCA_MISC* registers.

MCA_MISC0 is always available for each MCA bank. MCA_MISC1 through
MCA_MISC4 are considered available if MCA_MISC0[BlkPtr]=1.

Cache the value of MCA_MISC0[BlkPtr] for each bank and per CPU. This
needs to be done only during init. The values should be saved per CPU
to accommodate heterogeneous SMCA systems.

Redo smca_get_block_address() to directly return the block addresses.
Use the cached Block Pointer value to decide if the MCA_MISC1-4
addresses should be returned.

[PATCH v3 3/6] x86/MCE/AMD: Don't cache block addresses on SMCA systems

[Ghannam, Yazen]

From: Yazen Ghannam <yazen.ghannam@amd.com>

On legacy systems, the addresses of the MCA_MISC* registers need to be
recursively discovered based on a Block Pointer field in the registers.

On Scalable MCA systems, the register space is fixed, and particular
addresses can be derived by regular offsets for bank and register type.
This fixed address space includes the MCA_MISC* registers.

MCA_MISC0 is always available for each MCA bank. MCA_MISC1 through
MCA_MISC4 are considered available if MCA_MISC0[BlkPtr]=1.

Cache the value of MCA_MISC0[BlkPtr] for each bank and per CPU. This
needs to be done only during init. The values should be saved per CPU
to accommodate heterogeneous SMCA systems.

Redo smca_get_block_address() to directly return the block addresses.
Use the cached Block Pointer value to decide if the MCA_MISC1-4
addresses should be returned.

[v3,4/6] x86/MCE: Make number of MCA banks per_cpu

[Yazen Ghannam]

From: Yazen Ghannam <yazen.ghannam@amd.com>

The number of MCA banks is provided per logical CPU. Historically, this
number has been the same across all CPUs, but this is not an
architectural guarantee. Future AMD systems may have MCA bank counts
that vary between logical CPUs in a system.

This issue was partially addressed in

006c077041dc ("x86/mce: Handle varying MCA bank counts")

by allocating structures using the maximum number of MCA banks and by
saving the maximum MCA bank count in a system as the global count. This
means that some extra structures are allocated. Also, this means that
CPUs will spend more time in the #MC and other handlers checking extra
MCA banks.

Define the number of MCA banks as a per_cpu variable. Replace all uses
of mca_cfg.banks with this.

Also, use the per_cpu bank count when allocating per_cpu structures.

[v3,5/6] x86/MCE: Save MCA control bits that get set in hardware

[Yazen Ghannam]

From: Yazen Ghannam <yazen.ghannam@amd.com>

The OS is expected to write all bits in MCA_CTL. However, only
implemented bits get set in the hardware.

Read back MCA_CTL so that the value in the hardware is saved and
reported through sysfs.

[PATCH v3 4/6] x86/MCE: Make number of MCA banks per_cpu

[Ghannam, Yazen]

From: Yazen Ghannam <yazen.ghannam@amd.com>

The number of MCA banks is provided per logical CPU. Historically, this
number has been the same across all CPUs, but this is not an
architectural guarantee. Future AMD systems may have MCA bank counts
that vary between logical CPUs in a system.

This issue was partially addressed in

006c077041dc ("x86/mce: Handle varying MCA bank counts")

by allocating structures using the maximum number of MCA banks and by
saving the maximum MCA bank count in a system as the global count. This
means that some extra structures are allocated. Also, this means that
CPUs will spend more time in the #MC and other handlers checking extra
MCA banks.

Define the number of MCA banks as a per_cpu variable. Replace all uses
of mca_cfg.banks with this.

Also, use the per_cpu bank count when allocating per_cpu structures.

v2->v3:
* Drop pr_debug() message.
* Change commit reference format.

v1->v2:
* Drop export of new variable and leave injector code as-is.
* Add "mce_" prefix to new "num_banks" variable.

[PATCH v3 5/6] x86/MCE: Save MCA control bits that get set in hardware

[Ghannam, Yazen]

From: Yazen Ghannam <yazen.ghannam@amd.com>

The OS is expected to write all bits in MCA_CTL. However, only
implemented bits get set in the hardware.

Read back MCA_CTL so that the value in the hardware is saved and
reported through sysfs.

[v3,6/6] x86/MCE: Treat MCE bank as initialized if control bits set in hardware

[Yazen Ghannam]

From: Yazen Ghannam <yazen.ghannam@amd.com>

The OS is expected to write all bits to MCA_CTL for each bank. However,
some banks may be unused in which case the registers for such banks are
Read-as-Zero/Writes-Ignored. Also, the OS may not write any control bits
because of quirks, etc.

A bank can be considered uninitialized if the MCA_CTL register returns
zero. This is because either the OS did not write anything or because
the hardware is enforcing RAZ/WI for the bank.

Set a bank's init value based on if the control bits are set or not in
hardware.

Return an error code in the sysfs interface for uninitialized banks.

This looks like it will be a problem for Intel CPUs. If
we take a CPU offline, and then bring it back again, we
ues "b->ctl" to reinitialize the register in mce_reenable_cpu().

But Intel SDM says at the end of section "15.3.2.1 IA32_MCi_CTL_MSRs"

	"P6 family processors only allow the writing of all 1s or all
	0s to the IA32_MCi_CTL MSR."

I can put a vendor check on the read. Is that sufficient?

So that the sysfs files show the control values that are set in the hardware. It seemed like this would be more helpful than showing all 0xF's.

But I'm okay with dropping this patch. Patch 6 in this set depends on this, so it'll need to be dropped also.

Should I send out another version of this set?

Thanks,
Yazen

Yeah, but it has been like that since forever and it hasn't bugged
anybody. Probably because anybody doesn't even look at those files. As
Tony says:

"RAS is a lonely subsystem ... even EDAC gets more love."

:-)))

And adding yet another vendor check for this seemed just not worth it.

I simply zapped 5/6. I still think your 6/6 makes sense though.

We don't actually know if there are bits set in hardware until we read it back. So I don't think this is adding anything new.

Bah, of course. We need to read it first (pasting the whole function).
Now, __mcheck_cpu_init_clear_banks() gets called when we change
configuration too, in mce_cpu_restart() and if we do it this way, we'll
be rereading MCi_CTL each time but I don't see anything wrong with that.

Hmmm?

static void __mcheck_cpu_init_clear_banks(void)
{
        struct mce_bank *mce_banks = this_cpu_read(mce_banks_array);
        int i;

        for (i = 0; i < this_cpu_read(mce_num_banks); i++) {
                struct mce_bank *b = &mce_banks[i];

                rdmsrl(msr_ops.ctl(i), b->ctl);

                /* Bank is initialized if bits are set in hardware. */
                b->init = !!b->ctl;

                        wrmsrl(msr_ops.status(i), 0);
                }

        }

Intel doesn't "set any bits in hardware" ... so I think you'll just
get a 0x0 and disable everything.

I think the intent of the original patch was to find out
which bits are "implemented in hardware". I.e. throw all
1's at the register and see if any of them stick.

I don't object to the idea behind the patch. But if you want
to do this you just should not modify b->ctl.

So something like:
	

static void __mcheck_cpu_init_clear_banks(void)
{
        struct mce_bank *mce_banks = this_cpu_read(mce_banks_array);
	u64 tmp;
        int i;

        for (i = 0; i < this_cpu_read(mce_num_banks); i++) {
                struct mce_bank *b = &mce_banks[i];

                if (b->init) {
                        wrmsrl(msr_ops.ctl(i), b->ctl);
                        wrmsrl(msr_ops.status(i), 0);
			rdmsrl(msr_ops.ctl(i), tmp);

			/* Check if any bits implemented in h/w */
			b->init = !!tmp;
                }

        }
}

so that you get a feedback whether the setting has even succeeded or

... except that we unconditionally set ->init to 1 in
__mcheck_cpu_mce_banks_init() and I think we should query it. Btw, that
name __mcheck_cpu_mce_banks_init() is hideous too. I'll fix those up. In
the meantime, how does the below look like? The change is to tickle out
from the hw whether some CTL bits stick and then use that to determine
b->init setting:

Subject: [PATCH] x86/MCE: Determine MCA banks' init state properly

The OS is expected to write all bits to MCA_CTL for each bank,
thus enabling error reporting in all banks. However, some banks
may be unused in which case the registers for such banks are
Read-as-Zero/Writes-Ignored. Also, the OS may avoid setting some control
bits because of quirks, etc.

A bank can be considered uninitialized if the MCA_CTL register returns
zero. This is because either the OS did not write anything or because
the hardware is enforcing RAZ/WI for the bank.

Set a bank's init value based on if the control bits are set or not in
hardware. Return an error code in the sysfs interface for uninitialized
banks.

I think there are a couple of issues here.
1) The bank is being initialized without accounting for any quirks.
2) The bank is being initialized without having set up any handler or other appropriate setup.

Almost. __mcheck_cpu_init_clear_banks() a little bit later corrects
that. I guess I can drop the

	wrmsrl(msr_ops.status(i), 0);

in here because __mcheck_cpu_init_clear_banks() does that too.

Now, the

	wrmsrl(msr_ops.ctl(i), -1)
	rdmsrl(msr_ops.ctl(i), val);

method of throwing all 1s to see what sticks is what Intel wants, as
Tony said. Is that going to be a problem on AMD?

It is what we want in general ...  but there is this:

        if (c->x86_vendor == X86_VENDOR_INTEL) {
                /*
                 * SDM documents that on family 6 bank 0 should not be written

                 * But it's not aliased anymore on model 0x1a+
                 * Don't ignore bank 0 completely because there could be a
                 * valid event later, merely don't write CTL0.
                 */

                if (c->x86 == 6 && c->x86_model < 0x1A && cfg->banks > 0)
                        mce_banks[0].init = 0;

Which is a quirk for some models where we don't want to do

Ok, then we have to do what you suggested yesterday. I've added a short

Am I misreading the diff here? It doesn't look like you
needed to drop the

	if (!b->init)

and thus end up with that extra level on indent for the rest
of the function.

The issue seems to be that the allocation is now happening on CPUs other than CPU0.

Patch 2 in this set has the same issue. I didn't see it until I turned on the "Lock Debugging" config options.

> [    1.344284] BUG: sleeping function called from invalid context at mm/slab.h:418

This message comes from ___might_sleep() which checks the system_state.

On CPU0, system_state=SYSTEM_BOOTING.

On every other CPU, system_state=SYSTEM_SCHEDULING, and that's the only system_state where the message is shown.

Changing GFP_KERNEL to GFP_ATOMIC seems to be a fix. Is this appropriate? Or do you think there's something else we could try?

Thanks,

Right, the check in ___might_sleep().

From: Documentation/core-api/memory-allocation.rst

  * If you think that accessing memory reserves is justified and the kernel
    will be stressed unless allocation succeeds, you may use ``GFP_ATOMIC``.


I don't think the MCA banks representation justifies accessing memory
reserves.

Can we do instead:

-static DEFINE_PER_CPU_READ_MOSTLY(struct mce_bank *, mce_banks_array);
+static DEFINE_PER_CPU_READ_MOSTLY(struct mce_bank, mce_banks_array[MAX_NR_BANKS]);

which should be something like 9*32 = 288 bytes per CPU.

Unless you have a better idea...

Where did you get the "9" from?  struct mce_bank looks to
be over 50 bytes.

Still only 1.5K per cpu though.

Patch 2/6 changes that:

 struct mce_bank {

Yah, I think that using static per-CPU memory should be better than
GFP_ATOMIC.

I did a bit more testing and I noticed that writing "0" disables a bank with no way to reenable it.

For example:
1) Read bank10.
	a) Succeeds; returns "fffffffffffffff".
2) Write "0" to bank10.
	a) Succeeds; hardware register is set to "0".
	b) Hardware register is checked, and b->init=0.
3) Read bank10.
	a) Fails, because b->init=0.
4) Write non-zero value to bank10 to reenable it.
	a) Fails, because b->init=0.
5) Reboot needed to reset bank.

Is that okay?

Yazen

Nope, that doesn't sound correct to me.

I guess the cleanest way to handle his properly would be to have a
function called something like __mcheck_cpu_init_banks() which gets
called in mcheck_cpu_init() after the quirks have run and then does the
final poking of the banks and sets b->init properly.

__mcheck_cpu_init_clear_banks() should then be renamed to
__mcheck_cpu_clear_banks() to denote that it only clears the banks and
would only do:

                if (!b->init)
                        continue;

                wrmsrl(msr_ops.ctl(i), b->ctl);
                wrmsrl(msr_ops.status(i), 0);

And then sprinkle some commenting to not forget the scheme again.

Yeah, this sounds clean to me but you guys might have a better idea...

Thx.

Would you mind if the function name stayed the same? The reason is that MCA_CTL is written here, which is the "init" part, and MCA_STATUS is cleared.

I can use another name for the check, e.g. __mcheck_cpu_check_banks() or __mcheck_cpu_banks_check_init().

Nevermind, leave it as is. I'll fix it up ontop. I don't like that
"__mcheck_cpu_init" prefixing there which is a mouthful and should
simply be "mce_cpu_<do_stuff>" to denote that it is a function which is
run on a CPU to setup stuff.

Yeah, I agree.

I have another version of this set that I can send today. It includes the changes for this patch and also includes the fix for the locking bug message.

Should I send out the new version? Or do you want me to wait for any fixes on top of the current version?

I don't understand - I think we said to feel free to rework it all by using

https://git.kernel.org/pub/scm/linux/kernel/git/bp/bp.git/log/?h=rc0%2b3-ras

and reworking the whole branch to accomodate the changes and then
sending a whole new series...

Right, I took that branch, squashed the locking fix into patch 2, fixed up the remaining patches, and then redid the last patch.

I plan to send the result as a v4 of this patchset with all the links, version history, etc. Is that what you mean? Sorry, if I misunderstood.

So I'm staring at this and I can't say that I'm getting any good ideas:

I wanna get rid of that ugly "__mcheck_cpu_" prefix but the replacements
I can think of right now, are crap:

* I can call them all "cpu_<bla>" but then they look like generic
cpu-setup functions which come from kernel/cpu.c or so.

* I can prefix them with "mce_cpu" but when you do them all, it becomes
a block of "mce_cpu_" stuff which ain't more readable either. And
besides, those are static functions so they shouldn't need the prefix.
But I'd like the naming to denote that they're doing per-CPU setup
stuff. Which brings me to the previous point.

So no, don't have a good idea yet...
