[PATCH V2] powercap: intel_rapl: Do not change CLAMPING bit if ENABLE bit cannot be changed

by Zhang Rui

PL1 cannot be disabled on some platforms. The ENABLE bit is still set after software clears it. This behavior leads to a scenario where, upon user request to disable the Power Limit through the powercap sysfs, the ENABLE bit remains set while the CLAMPING bit is inadvertently cleared. According to the Intel Software Developer's Manual, the CLAMPING bit, "When set, allows the processor to go below the OS requested P states in order to maintain the power below specified Platform Power Limit value." Thus this means the system may operate at higher power levels than intended on such platforms. Enhance the code to check ENABLE bit after writing to it, and stop further processing if ENABLE bit cannot be changed.

[PATCH] i2c/designware: Fix an initialization issue

by Michael J. Ruhl

The i2c_dw_xfer_init() function requires msgs and msg_write_idx from the dev context to be initialized. amd_i2c_dw_xfer_quirk() inits msgs and msgs_num, but not msg_write_idx. This could allow an out of bounds access (of msgs). Initialize msg_write_idx before calling i2c_dw_xfer_init().

[PATCH] drm/vkms: Fix race-condition between the hrtimer and the atomic commit

by Pranav Tyagi

From: Maíra Canal <mcanal(a)igalia.com> [ Upstream commit a0e6a017ab56936c0405fe914a793b241ed25ee0 ] Currently, it is possible for the composer to be set as enabled and then as disabled without a proper call for the vkms_vblank_simulate(). This is problematic, because the driver would skip one CRC output, causing CRC tests to fail. Therefore, we need to make sure that, for each time the composer is set as enabled, a composer job is added to the queue. In order to provide this guarantee, add a mutex that will lock before the composer is set as enabled and will unlock only after the composer job is added to the queue. This way, we can have a guarantee that the driver won't skip a CRC entry. This race-condition is affecting the IGT test "writeback-check-output", making the test fail and also, leaking writeback framebuffers, as the writeback job is queued, but it is not signaled. This patch avoids both problems. [v2]: * Create a new mutex and keep the spinlock across the atomic commit in order to avoid interrupts that could result in deadlocks.

[PATCH v2] Bluetooth: HCI: Set extended advertising data synchronously

by Christian Eggers

Currently, for controllers with extended advertising, the advertising data is set in the asynchronous response handler for extended adverstising params. As most advertising settings are performed in a synchronous context, the (asynchronous) setting of the advertising data is done too late (after enabling the advertising). Move setting of adverstising data from asynchronous response handler into synchronous context to fix ordering of HCI commands.

The critical opcode (HCI_OP_LE_SET_EXT_ADV_DATA) is only used in hci_set_ext_adv_data_sync(). Two of the callers already ensure that the advertising instance is disabled, so only hci_update_adv_data_sync() may need a quirk.

[PATCH v2] usb: hub: fix detection of high tier USB3 devices behind suspended hubs

by Mathias Nyman

USB3 devices connected behind several external suspended hubs may not be detected when plugged in due to aggressive hub runtime pm suspend. The hub driver immediately runtime-suspends hubs if there are no active children or port activity. There is a delay between the wake signal causing hub resume, and driver visible port activity on the hub downstream facing ports. Most of the LFPS handshake, resume signaling and link training done on the downstream ports is not visible to the hub driver until completed, when device then will appear fully enabled and running on the port. This delay between wake signal and detectable port change is even more significant with chained suspended hubs where the wake signal will propagate upstream first. Suspended hubs will only start resuming downstream ports after upstream facing port resumes. The hub driver may resume a USB3 hub, read status of all ports, not yet see any activity, and runtime suspend back the hub before any port activity is visible. This exact case was seen when conncting USB3 devices to a suspended Thunderbolt dock. USB3 specification defines a 100ms tU3WakeupRetryDelay, indicating USB3 devices expect to be resumed within 100ms after signaling wake. if not then device will resend the wake signal. Give the USB3 hubs twice this time (200ms) to detect any port changes after resume, before allowing hub to runtime suspend again.

[PATCH] [v2] x86/fpu: Delay instruction pointer fixup until after warning

by Dave Hansen

Changes from v1: * Fix minor typos * Use the more generic and standard ex_handler_default(). Had the original code used this helper, the bug would not have been there in the first place. -- From: Dave Hansen <dave.hansen(a)linux.intel.com> Right now, if XRSTOR fails a console message like this is be printed: Bad FPU state detected at restore_fpregs_from_fpstate+0x9a/0x170, reinitializing FPU registers. However, the text location (...+0x9a in this case) is the instruction *AFTER* the XRSTOR. The highlighted instruction in the "Code:" dump also points one instruction late. The reason is that the "fixup" moves RIP up to pass the bad XRSTOR and keep on running after returning from the #GP handler. But it does this fixup before warning. The resulting warning output is nonsensical because it looks like the non-FPU-related instruction is #GP'ing. Do not fix up RIP until after printing the warning. Do this by using the more generic and standard ex_handler_default().

Yes Test regression: stable-rc 5.4 and 5.10 Reported-by: Linux Kernel Functional Testing <lkft(a)linaro.org> fanotify01.c:339: TFAIL: fanotify_mark(fd_notify, 0x00000001, 0x00000008, -100, ".") expected EXDEV: ENODEV (19) The test expected fanotify_mark() to fail with EXDEV, but received ENODEV instead. This indicates a potential mismatch between updated LTP test expectations and the behavior of the 5.4 kernel’s fanotify implementation.
