10 daysConvert 'alloc_flex' family to use the new default GFP_KERNEL argumentLinus Torvalds-1/+1
This is the exact same thing as the 'alloc_obj()' version, only much smaller because there are a lot fewer users of the *alloc_flex() interface. As with alloc_obj() version, this was done entirely with mindless brute force, using the same script, except using 'flex' in the pattern rather than 'objs*'.

10 daysConvert 'alloc_obj' family to use the new default GFP_KERNEL argumentLinus Torvalds-4/+4
This was done entirely with mindless brute force, using git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' | xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/' to convert the new alloc_obj() users that had a simple GFP_KERNEL argument to just drop that argument. Note that due to the extreme simplicity of the scripting, any slightly more complex cases spread over multiple lines would not be triggered: they definitely exist, but this covers the vast bulk of the cases, and the resulting diff is also then easier to check automatically. For the same reason the 'flex' versions will be done as a separate conversion. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
10 daystreewide: Replace kmalloc with kmalloc_obj for non-scalar typesKees Cook-5/+5
This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook <kees@kernel.org>

2026-01-13interconnect: Add kunit tests for core functionalityKuan-Wei Chiu-0/+340
The interconnect framework currently lacks in-tree unit tests to verify the core logic in isolation. This makes it difficult to validate regression stability when modifying the provider/consumer APIs or aggregation logic. Introduce a kunit test suite that verifies the fundamental behavior of the subsystem. The tests cover: - Provider API (node creation, linking, topology construction). - Consumer API (path enabling/disabling, bandwidth requests). - Standard aggregation logic (accumulating bandwidth across links). - Bulk operations for setting bandwidth on multiple paths. The suite simulates a simple SoC topology with multiple masters and a shared bus to validate traffic aggregation behavior in a controlled software environment, without requiring specific hardware or Device Tree support.

2025-12-21interconnect: mediatek: Aggregate bandwidth with saturating addNicolas Frattaroli-1/+4
By using a regular non-overflow-checking add, the MediaTek icc-emi driver will happy wrap at U32_MAX + 1 to 0. As it's common for the interconnect core to fill in INT_MAX values, this is not a hypothetical situation, but something that actually happens in regular use. This would be pretty disasterous if anything used this driver. Replace the addition with an overflow-checked addition from overflow.h, and saturate to U32_MAX if an overflow is detected.

2025-12-21interconnect: mediatek: Don't hijack parent deviceNicolas Frattaroli-2/+2
If the intention is that users of the interconnect declare their relationship to the child icc_emi node of the dvfsrc controller, then this code never worked. That's because it uses the parent dvfsrc device as the device it passes to the interconnect core framework, which means all the OF parsing is broken. Use the actual device instead, and pass the dvfsrc parent into the dvfsrc calls.

This enables QoS configuration for QNOC type device which can be found on SA8775P platform. It enables QoS configuration for master ports with predefined priority and urgency forwarding. This helps in prioritizing the traffic originating from different interconnect masters at NOC. The system may function normally without this feature. However, enabling QoS helps optimize latency and bandwidth across subsystems like CPU, GPU, and multimedia engines, which becomes important in high-throughput scenarios. This is a feature aimed at performance enhancement to improve system performance under concurrent workloads. * icc-sa8775p dt-bindings: interconnect: add reg and clocks properties to enable QoS on sa8775p interconnect: qcom: sa8775p: enable QoS configuration Link: https://lore.kernel.org/r/20251001073344.6599-1-odelu.kukatla@oss.qualcomm.com Signed-off-by: Georgi Djakov <djakov@kernel.org>
2025-10-31Merge branch 'icc-sdx75' into icc-nextGeorgi Djakov-28/+0
Drop the QPIC interconnect and BCM nodes for the SDX75 SoC. The reason is that this QPIC BCM resource is already defined as a RPMh clock in clk-rpmh driver as like other SDX SoCs. So it is wrong to describe the same resource in two different providers. Also, without this series, the NAND driver fails to probe on SDX75 as the interconnect sync state disables the QPIC nodes as there were no clients voting for this ICC resource. However, the NAND driver had already voted for this BCM resource through the clk-rpmh driver. Since both votes come from Linux, RPMh was unable to distinguish between these two and ends up disabling the resource during sync state. * icc-sdx75 interconnect: qcom: sdx75: Drop QPIC interconnect and BCM nodes dt-bindings: interconnect: qcom: Drop QPIC_CORE IDs Link: https://lore.kernel.org/r/20250926-sdx75-icc-v2-0-20d6820e455c@oss.qualcomm.com> Signed-off-by: Georgi Djakov <djakov@kernel.org>

2025-10-31interconnect: debugfs: Fix incorrect error handling for NULL pathKuan-Wei Chiu-1/+6
The icc_commit_set() function, used by the debugfs interface, checks the validity of the global cur_path pointer using IS_ERR_OR_NULL(). However, in the specific case where cur_path is NULL, while IS_ERR_OR_NULL(NULL) correctly evaluates to true, the subsequent call to PTR_ERR(NULL) returns 0. This causes the function to return a success code (0) instead of an error, misleading the user into believing their bandwidth request was successfully committed when, in fact, no operation was performed. Fix this by adding an explicit check to return -EINVAL if cur_path is NULL. This prevents silent failures and ensures that an invalid operational sequence is immediately and clearly reported as an error.

2025-10-31interconnect: qcom: sdx75: Drop QPIC interconnect and BCM nodesRaviteja Laggyshetty-28/+0
As like other SDX SoCs, SDX75 SoC's QPIC BCM resource was modeled as a RPMh clock in clk-rpmh driver. However, for SDX75, this resource was also described as an interconnect and BCM node mistakenly. It is incorrect to describe the same resource in two different providers, as it will lead to votes from clients overriding each other. Hence, drop the QPIC interconnect and BCM nodes and let the clients use clk-rpmh driver to vote for this resource. Without this change, the NAND driver fails to probe on SDX75, as the interconnect sync state disables the QPIC nodes as there were no clients voting for this ICC resource. However, the NAND driver had already voted for this BCM resource through the clk-rpmh driver. Since both votes come from Linux, RPMh was unable to distinguish between these two and ends up disabling the QPIC resource during sync state.
