[PATCH 00/10] Fix AMD IOMMU faults in kdump kernel

[Baoquan He]

This is a draft patchset trying to fix the issue that AMD IOMMU doesn't
work well in kdump kernel. The patch arrangement is not foraml, just
presenting what I have done and what's the problem being encountered
currently.


It contains 3 parts.

1) Clean up patch
  Patch 1/10, 2/10, 3/10 are code clean up patches, which later part will
  be based on.

2) IO page mapping
  Patch 4/10 ~ 9/10
 .> Checking if it's in kdump kernel and previously enabled
 .> If yes do below operatons:
        .> Do not disable amd iommu and do not touch dev tables before coping old dev tables
        .> Copy dev table form old kernel and set the old domain id in amd_iommu_pd_alloc_bitmap
        .> Don't call update_domain() to set domain->pt_root to dev entries before device driver initialization. 
        .> Reset the pre-enabled status when the first __map_single() is called during device driver init

3)interrupt remapping
  Patch 10/10
 .> I didn't think of this well. Now I only copy the old irq table when it first calls get_irq_table().
  This need people's suggestion. Maybe not correct old irq table copy cause kdump kernel hang.

Now there are several problems I got:
Now there's always a hang when go into kdump kernel so that I can't test
futher if command buffer/envent buffer need be copied and where flush need
be called.

Kdump kernel hang and dump the call trace to show it happened in check_timer.
This is similar as people found when they debugged intel iommu issue.

work well after modify_irte(). I don't know why it happened. Though I
have copied the old irte tables.

The problem happened in check_timer(). Seems timer interrupt doesn't
work well after modify_irte(). I don't know why it happened. Though I
have copied the old irte tables.

Baoquan He (10):
  iommu/amd: Use standard bitmap operation to set bitmap
  iommu/amd: Adjust functons which get first/last devid by reading pci
    config
  iommu/amd: Get the first/last device of iommu earlier
  iommu/amd: Detect pre enabled translation
  iommu/amd: Add function copy_dev_tables
  iommu/amd: Add functions copy_command_buffer/copy_event_buffer
  iommu/amd: copy old dev tables and do not change it
  iommu/amd: Do not update the information of domain to devtables before
    device driver init
  iommu/amd: Clear the iommu pre enabled setting
  iommu/amd: Copy the old ir table

[PATCH 02/10] iommu/amd: Adjust functons which get first/last devid by reading pci config

[Baoquan He]

The old functon find_last_devid_on_pci not only gets the last devid, but calls
update_last_devid(). Now adjust the function definition to make it be consistent
with its name. Meanwhile add a new function find_first_devid_on_pci for later use.

iommu->first_device/last_device are needed by function init_iommu_from_acpi()

could be late. In this patch put them earlier.

[PATCH 04/10] iommu/amd: Detect pre enabled translation

[Baoquan He]

Add functions to check whether translation is already enabled in IOMMU.
Maybe it need be checked per IOMMU. Currently for debugging I didn't do
like that.

[PATCH 06/10] iommu/amd: Add functions copy_command_buffer/copy_event_buffer

[Baoquan He]

Copy command buffer and event buffer from the old to kdump kernel.

Still there are 2 problems:
  1) Not very sure if this is necessary. If do not copy the old command buffer, and
only set the newly allocated command buffer, is there anything wrong?

  2) If copy is needed, do we need to take care of the head and tail pointers? Since
in section 3.3 of AMD IOMMU spec it says: "Any or all command buffer entries may be
copied from the old command buffer to the new and software must set the head and tail
pointers appropriately." However from the spec the command buffer head pointer and
tail register store an offset from the base address, which point to the next command
to be read/written separately.

in section 3.3 of AMD IOMMU spec it says: "Any or all command buffer entries may be
copied from the old command buffer to the new and software must set the head and tail
pointers appropriately." However from the spec the command buffer head pointer and
tail register store an offset from the base address, which point to the next command
to be read/written separately.

[PATCH 06/10] iommu/amd: Add functions copy_command_buffer/copy_event_buffer

[Baoquan He]

Copy command buffer and event buffer from the old to kdump kernel.

Still there are 2 problems:
  1) Not very sure if this is necessary. If do not copy the old command buffer, and
only set the newly allocated command buffer, is there anything wrong?

  2) If copy is needed, do we need to take care of the head and tail pointers? Since
in section 3.3 of AMD IOMMU spec it says: "Any or all command buffer entries may be
copied from the old command buffer to the new and software must set the head and tail
pointers appropriately." However from the spec the command buffer head pointer and
tail register store an offset from the base address, which point to the next command
to be read/written separately.

[PATCH 08/10] iommu/amd: Do not update the information of domain to devtables before device driver init

[Baoquan He]

update_domain() is the only place where domain->pt_root will be got and
set into dev entry. So before the device driver initialization we do
nothing if it's in previously enabled translation status.

No, there is no need to copy command and event buffers. Just make sure
they get re-initialized and flush all iommu caches after setting the new
device table.

Hmm, this leaves the old device-table in place and removes flushing the

There is probably a better place to do this somewhere in the

Is it necessary to copy the old ir tables? On AMD these tables are
per-device, so it is probably the best to handle them like the io
page-tables and just update the pointer to it in the device-table upon
interrupt initialization.

Is it necessary to copy the old ir tables? On AMD these tables are
per-device, so it is probably the best to handle them like the io
page-tables and just update the pointer to it in the device-table upon
interrupt initialization.

Thanks for your reviewing.

I did a lot of tests. Seems that it doesn't matter with copy or without
a copy. And it's also OK even completely ignore the command buffer and
event log handling here.

Yeah, that's what I thought at that time. no iommu-caches flushing will
cause the timer bug I mentioned in cover letter. Later I added
iommu_flush_dte(iommu, devid) if the related amd_iommu_dev_table[devid]
need be copied, then timer interupt bug disappeared.

Now the timer interrupt bug disappeared, but I may not handle the irq
remapping correctly. Currently I add another function copy_irq_table()
to fill out the table->table if the irq remapping table existed in
amd_iommu_dev_table[devid].data[2]. This is called in copy_dev_tables().
However my ata hard disk always startup wrongly, then the kdump failed
because no root disk. From log and adding dump_stack() it should be the
irq remapping issues, always there are many lines of message triggered
by modify_irte() calling like below:

*****************************
AMD-Vi: Completion-Wait loop timed out
*****************************

I don't know which part of irq remapping handling I didn't noticed. The
attachment is the kdump boot log with my current debugging code. If you
think that's helpful I can arrange and repost another round of draft
patch sets.


static void copy_irq_table(u16 devid)
{
        struct irq_remap_table *table = NULL;
        u16 alias;
        u64 dte;

        alias = amd_iommu_alias_table[devid];
        table = irq_lookup_table[alias];
        if (table) {
                irq_lookup_table[devid] = table;
                return;
        }
        dte     = amd_iommu_dev_table[devid].data[2];
        dte &= DTE_IRQ_PHYS_ADDR_MASK;
        if(!dte)
                return;

        table = kzalloc(sizeof(*table), GFP_ATOMIC);
        if (!table){
                pr_warn("AMD-Vi: amd irq table allocation failed\n");
                return;
        }
        table->table = ioremap_cache(dte, MAX_IRQS_PER_TABLE * sizeof(u32));
        irq_lookup_table[devid] = table;
}

Now the timer interrupt bug disappeared, but I may not handle the irq
remapping correctly. Currently I add another function copy_irq_table()
to fill out the table->table if the irq remapping table existed in
amd_iommu_dev_table[devid].data[2]. This is called in copy_dev_tables().
However my ata hard disk always startup wrongly, then the kdump failed
because no root disk. From log and adding dump_stack() it should be the
irq remapping issues, always there are many lines of message triggered
by modify_irte() calling like below:

*****************************
AMD-Vi: Completion-Wait loop timed out
*****************************

I don't know which part of irq remapping handling I didn't noticed. The
attachment is the kdump boot log with my current debugging code. If you
think that's helpful I can arrange and repost another round of draft
patch sets.


static void copy_irq_table(u16 devid)
{
        struct irq_remap_table *table = NULL;
        u16 alias;
        u64 dte;

        alias = amd_iommu_alias_table[devid];
        table = irq_lookup_table[alias];
        if (table) {
                irq_lookup_table[devid] = table;
                return;
        }
        dte     = amd_iommu_dev_table[devid].data[2];
        dte &= DTE_IRQ_PHYS_ADDR_MASK;
        if(!dte)
                return;

        table = kzalloc(sizeof(*table), GFP_ATOMIC);
        if (!table){
                pr_warn("AMD-Vi: amd irq table allocation failed\n");
                return;
        }
        table->table = ioremap_cache(dte, MAX_IRQS_PER_TABLE * sizeof(u32));
        irq_lookup_table[devid] = table;
}

Now the timer interrupt bug disappeared, but I may not handle the irq
remapping correctly. Currently I add another function copy_irq_table()
to fill out the table->table if the irq remapping table existed in
amd_iommu_dev_table[devid].data[2]. This is called in copy_dev_tables().
However my ata hard disk always startup wrongly, then the kdump failed
because no root disk. From log and adding dump_stack() it should be the
irq remapping issues, always there are many lines of message triggered
by modify_irte() calling like below:

*****************************
AMD-Vi: Completion-Wait loop timed out
*****************************

I don't know which part of irq remapping handling I didn't noticed. The
attachment is the kdump boot log with my current debugging code. If you
think that's helpful I can arrange and repost another round of draft
patch sets.


static void copy_irq_table(u16 devid)
{
        struct irq_remap_table *table = NULL;
        u16 alias;
        u64 dte;

        alias = amd_iommu_alias_table[devid];
        table = irq_lookup_table[alias];
        if (table) {
                irq_lookup_table[devid] = table;
                return;
        }
        dte     = amd_iommu_dev_table[devid].data[2];
        dte &= DTE_IRQ_PHYS_ADDR_MASK;
        if(!dte)
                return;

        table = kzalloc(sizeof(*table), GFP_ATOMIC);
        if (!table){
                pr_warn("AMD-Vi: amd irq table allocation failed\n");
                return;
        }
        table->table = ioremap_cache(dte, MAX_IRQS_PER_TABLE * sizeof(u32));
        irq_lookup_table[devid] = table;
}
