| * drm/amdgpu: Fix integer overflow in amdgpu_gem_add_input_fence()Dan Carpenter2025-06-031-1/+1
| | | | | | | | | | | | | | | | | | | | The "num_syncobj_handles" is a u32 value that comes from the user via the ioctl. On 32bit systems the "sizeof(uint32_t) * num_syncobj_handles" multiplication can have an integer overflow. Use size_mul() to fix that.

| * drm/amdgpu: Fix integer overflow issues in amdgpu_userq_fence.cDan Carpenter2025-06-031-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch only affects 32bit systems. There are several integer overflows bugs here but only the "sizeof(u32) * num_syncobj" multiplication is a problem at runtime. (The last lines of this patch). These variables are u32 variables that come from the user. The issue is the multiplications can overflow leading to us allocating a smaller buffer than intended. For the first couple integer overflows, the syncobj_handles = memdup_user() allocation is immediately followed by a kmalloc_array(): syncobj = kmalloc_array(num_syncobj_handles, sizeof(*syncobj), GFP_KERNEL); In that situation the kmalloc_array() works as a bounds check and we haven't accessed the syncobj_handlesp[] array yet so the integer overflow is harmless. But the "num_syncobj" multiplication doesn't have that and the integer overflow could lead to an out of bounds access.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch updates the cleaner shader, which is responsible for initializing GPU resources such as Local Data Share (LDS), Vector General Purpose Registers (VGPRs), and Scalar General Purpose Registers (SGPRs). Changes include adjustments to register clearing and shader configuration. - Updated GPU resource initialization addresses in the cleaner shader from `be803080` to `be803000`. - Simplified the logic in the SGPR clearing section, ensuring all SGPRs are set to zero.

V2: use common register UVD_STATUS for readback (standard PCI MMIO behavior, i.e. readback post all writes to let the writes hit the hardware) add readback in ..._stop() for more coverage. Similar to the changes made for VCN v4.0.5 where readback to post the writes to avoid race with the doorbell, the addition of register readback support in other VCN versions is intended to prevent potential race conditions, even though such issues have not been observed yet. This change ensures consistency across different VCN variants and helps avoid similar issues. The overhead introduced is negligible.

On hotplug ports using in-band presence detect, the reset causes a Presence Detect Changed event, which mistakenly caused teardown and re-enumeration of the device. Drivers may need to annotate code that resets their device (Lukas Wunner) Virtualization: - Add an ACS quirk for Loongson Root Ports that don't advertise ACS but don't allow peer-to-peer transactions between Root Ports; the quirk allows each Root Port to be in a separate IOMMU group (Huacai Chen) Endpoint framework: - For fixed-size BARs, retain both the actual size and the possibly larger size allocated to accommodate iATU alignment requirements (Jerome Brunet) - Simplify ctrl/SPAD space allocation and avoid allocating more space than needed (Jerome Brunet) - Correct MSI-X PBA offset calculations for DesignWare and Cadence endpoint controllers (Niklas Cassel) - Align the return value (number of interrupts) encoding for pci_epc_get_msi()/pci_epc_ops::get_msi() and pci_epc_get_msix()/pci_epc_ops::get_msix() (Niklas Cassel) - Align the nr_irqs parameter encoding for pci_epc_set_msi()/pci_epc_ops::set_msi() and pci_epc_set_msix()/pci_epc_ops::set_msix() (Niklas Cassel) Common host controller library: - Convert pci-host-common to a library so platforms that don't need native host controller drivers don't need to include these helper functions (Manivannan Sadhasivam) Apple PCIe controller driver: - Extract ECAM bridge creation helper from pci_host_common_probe() to separate driver-specific things like MSI from PCI things (Marc Zyngier) - Dynamically allocate RID-to_SID bitmap to prepare for SoCs with varying capabilities (Marc Zyngier) - Skip ports disabled in DT when setting up ports (Janne Grunau) - Add t6020 compatible string (Alyssa Rosenzweig) - Add T602x PCIe support (Hector Martin) - Directly set/clear INTx mask bits because T602x dropped the accessors that could do this without locking (Marc Zyngier) - Move port PHY registers to their own reg items to accommodate T602x, which moves them around;

| * | PCI: Add CONFIG_MMU dependencyArnd Bergmann2025-04-231-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It turns out that there are no platforms that have PCI but don't have an MMU, so adding a Kconfig dependency on CONFIG_PCI simplifies build testing kernels for those platforms a lot, and avoids a lot of inadvertent build regressions. Add a dependency for CONFIG_PCI and remove all the ones for PCI specific device drivers that are currently marked not having it. There are a few platforms that have an optional MMU, but they usually cannot have PCI at all. The one exception is Coldfire MCF54xx, but this is mainly for historic reasons, and anyone using those chips should really use the MMU these days.

Along with the drm core abstractions and enough nova-core/nova-drm to use them. This is still all stub work under construction, to build the nova driver upstream. The other big NVIDIA related one is nouveau adds support for Hopper/Blackwell GPUs, this required a new GSP firmware update to 570.144, and a bunch of rework in order to support multiple fw interfaces. There is also the introduction of an asahi uapi header file as a precursor to getting the real driver in later, but to unblock userspace mesa packages while the driver is trapped behind rust enablement.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The eviction fence destroy path incorrectly calls dma_fence_put() on evf_mgr->ev_fence after releasing the ev_fence_lock. This introduces a potential use-after-unlock or race because another thread concurrently modifies evf_mgr->ev_fence. Fix this by grabbing a local reference to evf_mgr->ev_fence under the lock and using that for dma_fence_put() after waiting.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the MEC firmware supports chaining runlists of XNACK+/XNACK- processes, set SQ_CONFIG1 chicken bit and SET_RESOURCES bit 28. When the MEC/HWS supports it, KFD checks the XNACK+/XNACK- processes mix happens or not. If it does, enter over-subscription.
