2019-02-07drm/tegra: vic: Do not clear driver dataThierry Reding1-1/+0
Upon driver failure, the driver core will take care of clearing the driver data, so there's no need to do so explicitly in the driver. Reviewed-by: Dmitry Osipenko <digetx@gmail.com> Signed-off-by: Thierry Reding <treding@nvidia.com>
2019-02-07drm/tegra: Restrict IOVA space to DMA maskThierry Reding1-2/+3
On Tegra186 and later, the ARM SMMU provides an input address space that is 48 bits wide. However, memory clients can only address up to 40 bits. If the geometry is used as-is, allocations of IOVA space can end up in a region that cannot be addressed by the memory clients. To fix this, restrict the IOVA space to the DMA mask of the host1x device. Note that, technically, the IOVA space needs to be restricted to the intersection of the DMA masks for all clients that are attached to the IOMMU domain. In practice using the DMA mask of the host1x device is sufficient because all host1x clients share the same DMA mask. Signed-off-by: Thierry Reding <treding@nvidia.com>
2019-02-07drm/tegra: Setup shared IOMMU domain after initializationThierry Reding1-25/+29
Move initialization of the shared IOMMU domain after the host1x device has been initialized. At this point all the Tegra DRM clients have been attached to the shared IOMMU domain. This is important because Tegra186 and later use an ARM SMMU, for which the driver defers setting up the geometry for a domain until a device is attached to it. This is to ensure that the domain is properly set up for a specific ARM SMMU instance, which is unknown at allocation time.

2019-02-07drm/tegra: vic: Load firmware on demandThierry Reding1-17/+36
Loading the firmware requires an allocation of IOVA space to make sure that the VIC's Falcon microcontroller can read the firmware if address translation via the SMMU is enabled. However, the allocation currently happens at a time where the geometry of an IOMMU domain may not have been initialized yet. This happens for example on Tegra186 and later where an ARM SMMU is used. Domains which are created by the ARM SMMU driver postpone the geometry setup until a device is attached to the domain. This is because IOMMU domains aren't attached to a specific IOMMU instance at allocation time and hence the input address space, which defines the geometry, is not known yet. Work around this by postponing the firmware load until it is needed at the time where a channel is opened to the VIC. At this time the shared IOMMU domain's geometry has been properly initialized. As a byproduct this allows the Tegra DRM to be created in the absence of VIC firmware, since the VIC initialization no longer fails if the firmware can't be found.

2019-02-07drm/tegra: Store parent pointer in Tegra DRM clientsThierry Reding2-0/+3
Tegra DRM clients need access to their parent, so store a pointer to it upon registration. It's technically possible to get at this by going via the host1x client's parent and getting the driver data, but that's quite complicated and not very transparent. It's much more straightforward and natural to let the children know about their parent. Signed-off-by: Thierry Reding <treding@nvidia.com> Reviewed-by: Dmitry Osipenko <digetx@gmail.com>
2019-02-07gpu: host1x: Optimize CDMA push buffer memory usageThierry Reding1-4/+25
The host1x CDMA push buffer is terminated by a special opcode (RESTART) that tells the CDMA to wrap around to the beginning of the push buffer. To accomodate the RESTART opcode, an extra 4 bytes are allocated on top of the 512 * 8 = 4096 bytes needed for the 512 slots (1 slot = 2 words) that are used for other commands passed to CDMA. This requires that two memory pages are allocated, but most of the second page (4092 bytes) is never used. Decrease the number of slots to 511 so that the RESTART opcode fits within the page. Adjust the push buffer wraparound code to take into account push buffer sizes that are not a power of two. Signed-off-by: Thierry Reding <treding@nvidia.com>
2019-02-07gpu: host1x: Use correct semantics for HOST1X_CHANNEL_DMAENDThierry Reding1-2/+2
The HOST1X_CHANNEL_DMAEND is an offset relative to the value written to the HOST1X_CHANNEL_DMASTART register, but it is currently treated as an absolute address. This can cause SMMU faults if the CDMA fetches past a pushbuffer's IOMMU mapping. Properly setting the DMAEND prevents the CDMA from fetching beyond that address and avoid such issues. This is currently not observed because a whole (almost) page of essentially scratch space absorbs any excessive prefetching by CDMA. However, changing the number of slots in the push buffer can trigger these SMMU faults. Signed-off-by: Thierry Reding <treding@nvidia.com>

2019-02-07gpu: host1x: Support 40-bit addressingThierry Reding4-10/+62
Tegra186 and later support 40 bits of address space. Additional registers need to be programmed to store the full 40 bits of push buffer addresses. Since command stream gathers can also reside in buffers in a 40-bit address space, a new variant of the GATHER opcode is also introduced. It takes two parameters: the first parameter contains the lower 32 bits of the address and the second parameter contains bits 32 to 39. Signed-off-by: Thierry Reding <treding@nvidia.com>
2019-02-07gpu: host1x: Introduce support for wide opcodesThierry Reding2-0/+94
The CDMA push buffer can currently only handle opcodes that take a single word parameter. However, the host1x implementation on Tegra186 and later supports opcodes that require multiple words as parameters. Unfortunately the way the push buffer is structured, these wide opcodes cannot simply be composed of two regular opcodes because that could result in the wide opcode being split across the end of the push buffer and the final RESTART opcode required to wrap the push buffer around would break the wide opcode. One way to fix this would be to remove the concept of slots to simplify push buffer operations. However, that's not entirely trivial and should be done in a separate patch. For now, simply use a different function to push four-word opcodes into the push buffer. Technically only three words are pushed, with the fourth word used as padding to preserve the 2-word alignment required by the slots abstraction. The fourth word is always a NOP opcode. Additional care must be taken when the end of the push buffer is reached. If a four-word opcode doesn't fit into the push buffer without being split by the boundary, NOP opcodes will be introduced and the new wide opcode placed at the beginning of the push buffer.

2019-02-04gpu: host1x: Set up stream ID tableThierry Reding2-0/+46
In order to enable the MMIO path stream ID protection provided by the incarnation of host1x found in Tegra186 and later, the host1x must be provided with the list of stream ID register offsets for each of its clients. Some clients (such as VIC) have multiple stream ID registers that are assumed to be contiguous. The host1x is programmed with the base offset and a limit which provide the range of registers that the host1x needs to monitor for writes. Signed-off-by: Thierry Reding <treding@nvidia.com>

2019-01-04make 'user_access_begin()' do 'access_ok()'Linus Torvalds1-2/+13
Originally, the rule used to be that you'd have to do access_ok() separately, and then user_access_begin() before actually doing the direct (optimized) user access. But experience has shown that people then decide not to do access_ok() at all, and instead rely on it being implied by other operations or similar. Which makes it very hard to verify that the access has actually been range-checked. If you use the unsafe direct user accesses, hardware features (either SMAP - Supervisor Mode Access Protection - on x86, or PAN - Privileged Access Never - on ARM) do force you to use user_access_begin(). But nothing really forces the range check. By putting the range check into user_access_begin(), we actually force people to do the right thing (tm), and the range check vill be visible near the actual accesses. We have way too long a history of people trying to avoid them. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2019-01-04i915: fix missing user_access_end() in page fault exception caseLinus Torvalds1-0/+1
When commit fddcd00a49e9 ("drm/i915: Force the slow path after a user-write error") unified the error handling for various user access problems, it didn't do the user_access_end() that is needed for the unsafe_put_user() case. It's not a huge deal: a missed user_access_end() will only mean that SMAP protection isn't active afterwards, and for the error case we'll be returning to user mode soon enough anyway. But it's wrong, and adding the proper user_access_end() is trivial enough (and doing it for the other error cases where it isn't needed doesn't hurt). I noticed it while doing the same prep-work for changing user_access_begin() that precipitated the access_ok() changes in commit 96d4f267e40f ("Remove 'type' argument from access_ok() function").

2019-01-03Remove 'type' argument from access_ok() functionLinus Torvalds46-140/+117
Nobody has actually used the type (VERIFY_READ vs VERIFY_WRITE) argument of the user address range verification function since we got rid of the old racy i386-only code to walk page tables by hand. It existed because the original 80386 would not honor the write protect bit when in kernel mode, so you had to do COW by hand before doing any user access. But we haven't supported that in a long time, and these days the 'type' argument is a purely historical artifact. A discussion about extending 'user_access_begin()' to do the range checking resulted this patch, because there is no way we're going to move the old VERIFY_xyz interface to that model. And it's best done at the end of the merge window when I've done most of my merges, so let's just get this done once and for all. This patch was mostly done with a sed-script, with manual fix-ups for the cases that weren't of the trivial 'access_ok(VERIFY_xyz' form. There were a couple of notable cases: - csky still had the old "verify_area()" name as an alias. - the iter_iov code had magical hardcoded knowledge of the actual values of VERIFY_{READ,WRITE} (not that they mattered, since nothing really used it) - microblaze used the type argument for a debug printout but other than those oddities this should be a total no-op patch. I tried to fix up all architectures, did fairly extensive grepping for access_ok() uses, and the changes are trivial, but I may have missed something. Any missed conversion should be trivially fixable, though. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
