[PATCH v2] x86/fpu: Avoid writing LBR bit to IA32_XSS unless supported

by Mitchell Levy via B4 Relay

From: Mitchell Levy <levymitchell0(a)gmail.com> When computing which xfeatures are available, make sure that LBR is only present if both LBR is supported in general, as well as by XSAVES. There are two distinct CPU features related to the use of XSAVES as it applies to LBR: whether LBR is itself supported (strictly speaking, I'm not sure that this is necessary to check though it's certainly a good sanity check), and whether XSAVES supports LBR (see sections 13.2 and 13.5.12 of the Intel 64 and IA-32 Architectures Software Developer's Manual, Volume 1). Currently, the LBR subsystem correctly checks both (see intel_pmu_arch_lbr_init), however the xstate initialization subsystem does not. When calculating what value to place in the IA32_XSS MSR, xfeatures_mask_independent only checks whether LBR support is present, not whether XSAVES supports LBR. If XSAVES does not support LBR, this write causes #GP, leaving the state of IA32_XSS unchanged (i.e., set to zero, as its not written with other values, and its default value is zero out of RESET per section 13.3 of the arch manual). Then, the next time XRSTORS is used to restore supervisor state, it will fail with #GP (because the RFBM has zero for all supervisor features, which does not match the XCOMP_BV field). In particular, XFEATURE_MASK_FPSTATE includes supervisor features, so setting up the FPU will cause a #GP. This results in a call to fpu_reset_from_exception_fixup, which by the same process results in another #GP. Eventually this causes the kernel to run out of stack space and #DF.

[PATCH] arm64: dts: rockchip: Raise Pinebook Pro's panel backlight PWM frequency

by Dragan Simic

Increase the frequency of the PWM signal that drives the LED backlight of the Pinebook Pro's panel, from about 1.35 KHz (which equals to the PWM period of 740,740 ns), to exactly 8 kHz (which equals to the PWM period of 125,000 ns). Using a higher PWM frequency for the panel backlight, which reduces the flicker, can only be beneficial to the end users' eyes. On top of that, increasing the backlight PWM signal frequency reportedly eliminates the buzzing emitted from the Pinebook Pro's built-in speakers when certain backlight levels are set, which cause some weird interference with some of the components of the Pinebook Pro's audio chain. The old value for the backlight PWM period, i.e. 740,740 ns, is pretty much an arbitrary value that was selected during the very early bring-up of the Pinebook Pro, only because that value seemed to minimize horizontal line distortion on the display, which resulted from the old X.org drivers causing screen tearing when dragging windows around. That's no longer an issue, so there are no reasons to stick with the old PWM period value. The lower and the upper backlight PWM frequency limits for the Pinebook Pro's panel, according to its datasheet, are 200 Hz and 10 kHz, respectively. [1] These changes still leave some headroom, which may have some positive effects on the lifetime expectancy of the panel's backlight LEDs.

From: Johannes Berg <johannes.berg(a)intel.com> commit ce04abc3fcc62cd5640af981ebfd7c4dc3bded28 upstream. When userspace sets basic rates, it might send us some rates list that's empty or consists of invalid values only. We're currently ignoring invalid values and then may end up with a rates bitmap that's empty, which later results in a warning. Reject the call if there were no valid rates.

[PATCH] ice: Fix improper handling of refcount in ice_dpll_init_rclk_pins()

by Gui-Dong Han

This patch addresses a reference count handling issue in the ice_dpll_init_rclk_pins() function. The function calls ice_dpll_get_pins(), which increments the reference count of the relevant resources. However, if the condition WARN_ON((!vsi || !vsi->netdev)) is met, the function currently returns an error without properly releasing the resources acquired by ice_dpll_get_pins(), leading to a reference count leak. To resolve this, the patch introduces a goto unregister_pins; statement when the condition is met, ensuring that the resources are correctly released and the reference count is decremented before returning the error. This change prevents potential memory leaks and ensures proper resource management within the function. This bug was identified by an experimental static analysis tool developed by our team. The tool specializes in analyzing reference count operations and detecting potential issues where resources are not properly managed. In this case, the tool flagged the missing release operation as a potential problem, which led to the development of this patch.

While it does not advertise an ACS capability, peer-to-peer transactions are not possible between the individual functions. So it is ok to treat them as fully isolated.

This patch addresses an issue with improper reference count handling in the ice_sriov_set_msix_vec_count() function. Specifically, the function calls ice_get_vf_by_id(), which increments the reference count of the vf pointer. If the subsequent call to ice_get_vf_vsi() fails, the function currently returns an error without decrementing the reference count of the vf pointer, leading to a reference count leak. The correct behavior, as implemented in this patch, is to decrement the reference count using ice_put_vf(vf) before returning an error when vsi is NULL. This bug was identified by an experimental static analysis tool developed by our team. The tool specializes in analyzing reference count operations and identifying potential mismanagement of reference counts. In this case, the tool flagged the missing decrement operation as a potential issue, leading to this patch.
