2024-07-09venus: pm_helpers: Use dev_pm_genpd_set_hwmode to switch GDSC mode on V6Jagadeesh Kona
The Venus driver requires vcodec GDSC to be ON in SW mode for clock operations and move it back to HW mode to gain power benefits. Earlier, as there is no interface to switch the GDSC mode from GenPD framework, the GDSC is moved to HW control mode as part of GDSC enable callback and venus driver is writing to its POWER_CONTROL register to keep the GDSC ON from SW whereever required. But the POWER_CONTROL register addresses are not constant and can vary across the variants. Also as per the HW recommendation, the GDSC mode switching needs to be controlled from respective GDSC register and this is a uniform approach across all the targets. Hence use dev_pm_genpd_set_hwmode() API which controls GDSC mode switching using its respective GDSC register. In venus V6 variants, the vcodec gdsc gets enabled in SW mode by default with new HW_CTRL_TRIGGER flag and there is no need to switch it to SW mode again after enable, hence add check to avoid switching gdsc to SW mode again after gdsc enable. Similarly add check to avoid switching GDSC to HW mode before disabling the GDSC, so GDSC gets enabled in SW mode in the next enable.

2024-07-09clk: qcom: gdsc: Add set and get hwmode callbacks to switch GDSC modeJagadeesh Kona
Some GDSC client drivers require the GDSC mode to be switched dynamically to HW mode at runtime to gain the power benefits. Typically such client drivers require the GDSC to be brought up in SW mode initially to enable the required dependent clocks and configure the hardware to proper state. Once initial hardware set up is done, they switch the GDSC to HW mode to save power. At the end of usecase, they switch the GDSC back to SW mode and disable the GDSC. Introduce HW_CTRL_TRIGGER flag to register the set_hwmode_dev and get_hwmode_dev callbacks for GDSC's whose respective client drivers require the GDSC mode to be switched dynamically at runtime using dev_pm_genpd_set_hwmode() API.

2024-07-09PM: domains: Allow devices attached to genpd to be managed by HWUlf Hansson
Some power-domains may be capable of relying on the HW to control the power for a device that's hooked up to it. Typically, for these kinds of configurations the consumer driver should be able to change the behavior of power domain at runtime, control the power domain in SW mode for certain configurations and handover the control to HW mode for other usecases. To allow a consumer driver to change the behaviour of the PM domain for its device, let's provide a new function, dev_pm_genpd_set_hwmode(). Moreover, let's add a corresponding optional genpd callback, ->set_hwmode_dev(), which the genpd provider should implement if it can support switching between HW controlled mode and SW controlled mode. Similarly, add the dev_pm_genpd_get_hwmode() to allow consumers to read the current mode and its corresponding optional genpd callback, ->get_hwmode_dev(), which the genpd provider can also implement to synchronize the initial HW mode state in genpd_add_device() by reading back the mode from the hardware.

2024-07-09pmdomain: qcom: rpmhpd: Skip retention level for Power DomainsTaniya Das
In the cases where the power domain connected to logics is allowed to transition from a level(L)-->power collapse(0)-->retention(1) or vice versa retention(1)-->power collapse(0)-->level(L) will cause the logic to lose the configurations. The ARC does not support retention to collapse transition on MxC rails. The targets from SM8450 onwards the PLL logics of clock controllers are connected to MxC rails and the recommended configurations are carried out during the clock controller probes. The MxC transition as mentioned above should be skipped to ensure the PLL settings are intact across clock controller power on & off. On older targets that do not split MX into MxA and MxC does not collapse the logic and it is parked always at RETENTION, thus this issue is never observed on those targets.

https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into soc/drivers Qualcomm driver updates for v6.11 Support for Shared Memory (shm) Bridge is added, which provides a stricter interface for handling of buffers passed to TrustZone. The X1Elite platform is added to uefisecapp allow list, to instantiate the efivars implementation. A new in-kernel implementation of the pd-mapper (or servreg) service is introduced, to replace the userspace dependency for USB Type-C and battery management. Support for sharing interrupts across multiple bwmon instances is added, and a refcount imbalance issue is corrected. The LLCC support for recent platforms is corrected, and SA8775P support is added. A new interface is added to SMEM, to expose "feature codes". One example of the usecase for this is to indicate to the GPU driver which frequencies are available on the given device. The interrupt consumer and provider side of SMP2P is updated to provide more useful names in interrupt stats. Support for using the mailbox binding and driver for outgoing IPC interrupt in the SMSM driver is introduced. socinfo driver learns about SDM670 and IPQ5321, as well as get some updates to the X1E PMICs. pmic_glink is bumped to now support managing 3 USB Type-C ports. * tag 'qcom-drivers-for-6.11' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: (48 commits) soc: qcom: smp2p: Use devname for interrupt descriptions soc: qcom: smsm: Add missing mailbox dependency to Kconfig soc: qcom: add missing pd-mapper dependencies soc: qcom: icc-bwmon: Allow for interrupts to be shared across instances dt-bindings: interconnect: qcom,msm8998-bwmon: Add X1E80100 BWMON instances dt-bindings: interconnect: qcom,msm8998-bwmon: Remove opp-table from the required list firmware: qcom: tzmem: export devm_qcom_tzmem_pool_new() soc: qcom: add pd-mapper implementation soc: qcom: pdr: extract PDR message marshalling data soc: qcom: pdr: fix parsing of domains lists soc: qcom: pdr: protect locator_addr with the main mutex firmware: qcom: scm: clarify the comment in qcom_scm_pas_init_image() firmware: qcom: scm: add support for SHM bridge memory carveout firmware: qcom: tzmem: enable SHM Bridge support firmware: qcom: scm: add support for SHM bridge operations firmware: qcom: qseecom: convert to using the TZ allocator firmware: qcom: scm: make qcom_scm_qseecom_app_get_id() use the TZ allocator firmware: qcom: scm: make qcom_scm_lmh_dcvsh() use the TZ allocator firmware: qcom: scm: make qcom_scm_ice_set_key() use the TZ allocator firmware: qcom: scm: make qcom_scm_assign_mem() use the TZ allocator ...

This crash is because a NULL pointer is passed to page_address() in the sk_msg_recvmsg(). Due to the different implementations depending on the architecture, page_address(NULL) will trigger a panic on Loongarch platform but not on x86 platform. So this bug was hidden on x86 platform for a while, but now it is exposed on Loongarch platform. The root cause is that a zero length skb (skb->len == 0) was put on the queue. This zero length skb is a TCP FIN packet, which was sent by shutdown(), invoked in test_sockmap_skb_verdict_shutdown(): shutdown(p1, SHUT_WR); In this case, in sk_psock_skb_ingress_enqueue(), num_sge is zero, and no page is put to this sge (see sg_set_page in sg_set_page), but this empty sge is queued into ingress_msg list. And in sk_msg_recvmsg(), this empty sge is used, and a NULL page is got by sg_page(sge). Pass this NULL page to copy_page_to_iter(), which passes it to kmap_local_page() and to page_address(), then kernel panics. To solve this, we should skip this zero length skb. So in sk_msg_recvmsg(), if copy is zero, that means it's a zero length skb, skip invoking copy_page_to_iter(). We are using the EFAULT return triggered by copy_page_to_iter to check for is_fin in tcp_bpf.c.

2024-07-09gpio: virtuser: new virtual testing driver for the GPIO APIBartosz Golaszewski
The GPIO subsystem used to have a serious problem with undefined behavior and use-after-free bugs on hot-unplug of GPIO chips. This can be considered a corner-case by some as most GPIO controllers are enabled early in the boot process and live until the system goes down but most GPIO drivers do allow unbind over sysfs, many are loadable modules that can be (force) unloaded and there are also GPIO devices that can be dynamically detached, for instance CP2112 which is a USB GPIO expender. Bugs can be triggered both from user-space as well as by in-kernel users. We have the means of testing it from user-space via the character device but the issues manifest themselves differently in the kernel. This is a proposition of adding a new virtual driver - a configurable GPIO consumer that can be configured over configfs (similarly to gpio-sim) or described on the device-tree. This driver is aimed as a helper in spotting any regressions in hot-unplug handling in GPIOLIB.
