2024-02-22memory: tegra: Correct DLA client namesJon Hunter
Some of the names for the Tegra234 DLA clients are not unique and do not align with the name of the client ID definitions. Therefore, it is not possible to determine the exact DLA client from messages that print the client name. Fix this by correcting the DLA memory client names for Tegra234 to align with the name of the corresponding memory client ID. Note that although the client names are also used by the interconnect framework, interconnect support for the DLA clients has not been added and so this issue does not impact the interconnect support.

2023-12-19memory: tegra210-emc: Convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

2023-09-25iommu/tegra-gart: Remove tegra-gartJason Gunthorpe
Thierry says this is not used anymore, and doesn't think it makes sense as an iommu driver. The HW it supports is about 10 years old now and newer HW uses different IOMMU drivers. As this is the only driver with a GART approach, and it doesn't really meet the driver expectations from the IOMMU core, let's just remove it so we don't have to think about how to make it fit in. It has a number of identified problems: - The assignment of iommu_groups doesn't match the HW behavior - It claims to have an UNMANAGED domain but it is really an IDENTITY domain with a translation aperture. This is inconsistent with the core expectation for security sensitive operations - It doesn't implement a SW page table under struct iommu_domain so * It can't accept a map until the domain is attached * It forgets about all maps after the domain is detached * It doesn't clear the HW of maps once the domain is detached (made worse by having the wrong groups) Cc: Thierry Reding <treding@nvidia.com> Cc: Dmitry Osipenko <digetx@gmail.com> Acked-by: Thierry Reding <treding@nvidia.com> Reviewed-by: Lu Baolu <baolu.lu@linux.intel.com> Reviewed-by: Jerry Snitselaar <jsnitsel@redhat.com> Signed-off-by: Jason Gunthorpe <jgg@nvidia.com> Link: https://lore.kernel.org/r/6-v8-81230027b2fa+9d-iommu_all_defdom_jgg@nvidia.com Signed-off-by: Joerg Roedel <jroedel@suse.de>

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree.

Add check to ensure that "MRQ_EMC_DVFS_LATENCY" is supported by the BPMP-FW before making the MRQ request. Currently, if the BPMP-FW doesn't support this MRQ, then the "tegra186_emc_probe" fails. Due to this the Memory Interconnect initialization also doesn't happen. Memory Interconnect is not dependent on this MRQ and can initialize even when this MRQ is not supported in any platform.

However, a provider is currently only exposed on Tegra234 and this causes PCI on Tegra194 to defer probe indefinitely. Fix this by adding a dummy implementation on Tegra194.

Since commit 8b41fc4454e3 ("kbuild: create modules.builtin without Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations are used to identify modules. As a consequence, uses of the macro in non-modules will cause modprobe to misidentify their containing object file as a module when it is not (false positives), and modprobe might succeed rather than failing with a suitable error message. So remove it in the files in this commit, none of which can be built as modules.

2022-12-27memory: tegra: Remove clients SID override programmingAshish Mhetre
On newer Tegra releases, early boot SID override programming and SID override programming during resume is handled by bootloader. In the function tegra186_mc_program_sid() which is getting removed, SID override register of all clients is written without checking if secure firmware has allowed write on it or not. If write is disabled by secure firmware then it can lead to errors coming from secure firmware and hang in kernel boot. Also, SID override is programmed on-demand during probe_finalize() call of IOMMU which is done in tegra186_mc_client_sid_override() in this same file. This function does it correctly by checking if write is permitted on SID override register. It also checks if SID override register is already written with correct value and skips re-writing it in that case.

Pull drm updates from Dave Airlie: "The biggest highlight is that the accel subsystem framework is merged. Hopefully for 6.3 we will be able to line up a driver to use it.

There is also an ofdrm driver to take over offb on platforms it's used.
