Joerg Roedel ad9bc59173 iommu/amd: Finish TLB flush in amd_iommu_unmap()
commit ce76353f169a6471542d999baf3d29b121dce9c0 upstream.

The function only sends the flush command to the IOMMU(s),
but does not wait for its completion when it returns. Fix
that.

commit fda3bec12d0979aae3f02ee645913d66fbc8a26e upstream.

This is a 32-bit register. Apparently harmless on real hardware, but

Joerg Roedel 8e7439f32a iommu/amd: Don't clear DTE flags when modifying it
commit cbf3ccd09d683abf1cacd36e3640872ee912d99b upstream.

During device assignment/deassignment the flags in the DTE
get lost, which might cause spurious faults, for example
when the device tries to access the system management range.
Fix this by not clearing the flags with the rest of the DTE.

passed to TZ. The code which does this incorrectly
increments physical base address each time, besides
adding chunk size. Fix this.

Chintan Pandya 5ab7ef8486 iommu: msm: flush page tables at the end after map/unmap
Flushing the cache for each PTE update could be very time
consuming if the number of PTEs getting updated are in
order of few thousands. Instead, don't perform cache ops
for each PTE update and flush the updated page table once
at the end of map/unmap routine. This saves roughly 60%
of the total time spent by map/unmap calls. Few numbers
with/without this optimization applied.

Chintan Pandya 6d3d5c278e iommu: leave sizing calculations on domain->ops->map
Running a loop and handlling complex tasks in iommu_map
causes severe perf hit. Anyways, different IOMMU drivers
are taking care of sizing by themselves. So, hand-off
this task to ops->map.

Some numbers collected to show the benefits of removing
redundant code. Here these numbers are collected with
ops defined by msm_iommu driver.

Default:
    size       iommu_map  iommu_unmap

      4K            6 us         2 us
     64K           11 us         0 us

     20M         2843 us        17 us

With this patch:
    size       iommu_map  iommu_unmap

      4K            6 us         3 us
     64K            3 us         0 us

Only first 9 bits [8:0] indicates type of fault 'at'
the time of fault. So, fix the false positive by just
checking over fault indicator bits only.

Now that non-secure CB faults also gets routed to secure

enabled. This was the BUG but no one earlier called
custom fault handler from secure fault handler and remained
uncaught. Fix it by maintaining clock until we return.

Also, ensure that only for valid FSR values we enter and
invoke custom fault handlers.

Vinayak Menon 9a109614b4 iommu: msm: make iommu map and unmap atomic
Certain use cases require iommu map and unmap functions
to be called from atomic context. Remove all sleeping
calls and fix the locks to make these functions atomic.
The secure map and unmap functions are still non-atomic
since they have to invoke smc calls which are sleeping
functions right now.

Chintan Pandya e42549ecd2 iommu: msm: Correct the data type mis-matches in VA
MSM IOMMU driver presently supports mapping of virtual
addresses of 32-bit long only. Because of this, 32-bit
long virtual address was okay and some mis-matches were
silent. This is harmless but still buggy. Also, for
64-bit virtual address mapping, some API needs update.

Make input virtual address always 'unsigned long' and
trunk (if necessary) based on the page table format.

Chintan Pandya 8be859ed7f iommu: msm: Invalidate properly from iommu_unmap
TLB invalidation by VA will work for the given VA and
not the range of VA. So, for a region that spreads
across multiple PTEs, that need to call TLBIVA multiple
times. This is un-optimized.

Anyways, the present implementation also support single
TLBIVA only for the first VA and rest may be kept in
TLB as is. This is a problem. Fix this by upgrading
TLBIVA with TLBIASID which will do invalidation for
all the VAs for matching ASID.

We may still skip fixing this in iommu_map as iommu_map
is still indeed mapping one VA at a time.

Chintan Pandya 66ce877464 iommu: msm: Invoke secure fault handler for non-secure CBs
In case if IOMMU is secure, Linux cannot access global space.
At the time of CB fault, we look into global space registers
to get some information like faulting SID from secure CB
fault handler but not from non-secure CB fault handler. So,
handle CB interrupts by secure IRQ fault handler to get more
info.

We cannot unconditionally call into secure fault handler
because, in cases where we run Linux without any secure
environment, or the IOMMU is non-secure,  we want to fall
back on the non-secure fault handler.

Robin Murphy 1bbdb2e228 iommu: arm-smmu: set a more appropriate DMA mask
Since we use dma_map_page() as an architecture-independent means of
making page table updates visible to non-coherent SMMUs, we need to
have a suitable DMA mask set to discourage the DMA mapping layer from
creating bounce buffers and flushing those instead, if said page tables
happen to lie outside the default 32-bit mask.

Mitchel Humpherys 318dcce92a iommu/arm-smmu: print idr0 when translation support is not found
To aide in debugging, print the value of the IDR0 register when no
translation support is found, which would generally indicate a hardware
bug or missing clocks/power.

Thulium has a hardware errata that requires that we avoid using ASID 0.
Implement the workaround in the SMMU driver.

iommu_map_sg is the new preferred API over map_range. Switch
custom APIs to use it.

Laura Abbott b7c64d2138 drivers: iommu: Add iommu_map_sg for msm_iommu
iommu_map_sg is the newer, preferred API. Add a wrapper around
the existing map_range API for map_sg. Once all clients have been
successfully converted map_range can be removed.
