Add support for the Qualcomm Milos SoC to the protection domain mapper. Milos shares the same protection domain configuration as SM8550, so reuse the existing SM8550 domain data.

Similar to the case of commit d48708500610 ("soc: qcom: pmic_glink_altmode: Fix SVID=DP && unconnected edge case"), leaving the TBT altmode makes pmic_glink_altmode report a SVID=TBT && mux_ctrl=0 message. Said commit reordered the check such that the SVID is processed before checking for NO_CONN. Rework this to take into account valid values of mux_ctrl first and hopefully solve this for good..

2026-03-15soc: qcom: pmic_glink_altmode: Fix SVID=DP && unconnected edge caseKonrad Dybcio
The commit referenced in Fixes started evaluating the value of alt_port->mux_ctrl before checking the active SVID. This led to drm_aux_hpd_bridge_notify() no longer being called for the 'DP unplug' case. Perhaps somewhat interestingly, the firmware sends a notification with SVID=DP, mux_ctrl=MUX_CTRL_STATE_NO_CONN and pin_assignment=0 on unplug. 'pin_assignment' was previously interpreted as a bitfield excerpt from the second byte of the DP pg_altmode payload (and stored as an u8). That value is used in pmic_glink_altmode_sc8280xp_notify(), decremented by 1 (DPAM_HPD_A). Previously, this would result in an u8 underflow that would rollover to 0xff (which prior to the Fixes patch would have caused a pmic_glink_altmode_safe() and 'disconnected' bridge notification). That check was removed, without a replacement. Resolve this issue by making sure the SID=DP && mux_ctrl=NO_CONN combo once again results in a HPD bridge notification.

This resolves mismatches that occur when multiple client drivers vote for the same slice or when llcc_slice_getd() is called multiple times.

2026-03-15soc: qcom: smp2p: Add support for smp2p v2Chris Lew
smp2p v2 adds support for allowing remote processors to write outbound smp2p items without completing the feature negotiation. This is required for processors that start before linux to write out signals like error and clock ready and unblock their bootup. If a remote processor only supports v1, smp2p can version down by mirroring the peer version during the negotiation stage. When using smp2p version 2, the remote does not wait for the ssr ack before setting the items. To accommodate this, set the last_value of all the entries to 0 when SSR is detected. This forces smp2p to detect the new values written by the remote. Because the SSR ack is skipped, the down transition of bits is missed in smp2p version 2.

A remoteproc booted during earlier boot stages such as UEFI or the bootloader, may need to be attached to without restarting the remoteproc hardware. To do this the remoteproc will need to check the ready and handover states in smp2p without an interrupt notification. Create qcom_smp2p_start_in() to initialize the shadow state without notifying clients because these early events happened in the past. Add support for the .irq_get_irqchip_state callback so remoteproc can read the current state of the fatal, ready and handover bits.

When QMAN_FQ_FLAG_DYNAMIC_FQID is set, there's a race condition between fq_table[fq->idx] state and freeing/allocating from the pool and WARN_ON(fq_table[fq->idx]) in qman_create_fq() gets triggered. Indeed, we can have: Thread A Thread B qman_destroy_fq() qman_create_fq() qman_release_fqid() qman_shutdown_fq() gen_pool_free() -- At this point, the fqid is available again -- qman_alloc_fqid() -- so, we can get the just-freed fqid in thread B -- fq->fqid = fqid; fq->idx = fqid * 2; WARN_ON(fq_table[fq->idx]); fq_table[fq->idx] = fq; fq_table[fq->idx] = NULL; And adding some logs between qman_release_fqid() and fq_table[fq->idx] = NULL makes the WARN_ON() trigger a lot more. To prevent that, ensure that fq_table[fq->idx] is set to NULL before gen_pool_free() is called by using smp_wmb().

2026-02-21Convert more 'alloc_obj' cases to default GFP_KERNEL argumentsLinus Torvalds
This converts some of the visually simpler cases that have been split over multiple lines. I only did the ones that are easy to verify the resulting diff by having just that final GFP_KERNEL argument on the next line. Somebody should probably do a proper coccinelle script for this, but for me the trivial script actually resulted in an assertion failure in the middle of the script. I probably had made it a bit _too_ trivial. So after fighting that far a while I decided to just do some of the syntactically simpler cases with variations of the previous 'sed' scripts. The more syntactically complex multi-line cases would mostly really want whitespace cleanup anyway. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2026-02-21Convert 'alloc_obj' family to use the new default GFP_KERNEL argumentLinus Torvalds
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>
2026-02-21treewide: Replace kmalloc with kmalloc_obj for non-scalar typesKees Cook
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>
