We want to allow host caps to be changed dynamically via debugfs, so for these to have an effect, ensure that the card type reselection is always applied even if the card is old. Signed-off-by:

The STM32 SDMMC peripheral (at least for the STM32F429, STM32F469 and STM32F746, which are all the currently supported devices using periphid 0x00880180) requires DMA to be performed in peripheral flow controller mode. From the STM32F74/5 reference manual, section 35.3.2: "SDMMC host allows only to use the DMA in peripheral flow controller mode. DMA stream used to serve SDMMC must be configured in peripheral flow controller mode" This patch adds a variant option to control peripheral flow control and enables it for the STM32 variant.

The OEMID is an 8-bit binary number rather than 16-bit as the current code parses for. The OEMID occupies bits [111:104] in the CID register, see the eMMC spec JESD84-B51 paragraph 7.2.3. It seems that the 16-bit comes from the legacy MMC specs (v3.31 and before). Let's fix the parsing by simply move to use 8-bit instead of 16-bit. This means we ignore the impact on some of those old MMC cards that may be out there, but on the other hand this shouldn't be a problem as the OEMID seems not be an important feature for these cards.

`strncpy` is deprecated for use on NUL-terminated destination strings [1] and as such we should prefer more robust and less ambiguous string interfaces. We expect `vub300->vub_name` to be NUL-terminated based on its uses with format strings: | dev_info(&vub300->udev->dev, "using %s for SDIO offload processing\n", | vub300->vub_name); NUL-padding is not needed. We can see cleaning out vub_name simply consists of: | vub300->vub_name[0] = 0; Considering the above, for all 11 cases a suitable replacement is `strscpy` [2] due to the fact that it guarantees NUL-termination on the destination buffer without unnecessarily NUL-padding. To be clear, there is no existing bug in the current implementation as the string literals are all small enough as to not cause a buffer overread. Nonetheless, this gets us 11 steps closer to removing strncpy uses.

Prepare for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions). As found with Coccinelle[1], add __counted_by for struct jmb38x_ms.

By dynamically adjusting the host->hsq_depth, based upon the buffer size being 4k and that we get at least two I/O write requests in flight, we can improve the throughput a bit. This is typical for a random I/O write pattern. More precisely, by dynamically changing the number of requests in flight from 2 to 5, we can on some platforms observe ~4-5% increase in throughput.

MMC_SDHI_INTERNAL_DMAC config option has dependency on ARM64 and R7S9210/R8A77470 this dependency will keep growing for future SoCs for varying architectures. So to simplify this configuration make MMC_SDHI_INTERNAL_DMAC solely depend on ARCH_RENESAS, as all Renesas SoCs inherently depend on the ARCH_RENESAS config option. This allows selecting MMC_SDHI_INTERNAL_DMAC config option for RZ/Five SoC which is based on RISC-V architecture. Signed-off-by:

The Qualcomm SDHCI controller lists optional clocks, but still expects fixed order of them and does not allow to skip such clocks if further one in the list is needed. These optional clocks are truly optional, so we need to allow the list to have different orders. The clocks are: - ice: used for Inline Crypto Engine, which is actually separate block and merging it with SDHCI is not a requirement, - bus: clock for SDCC bus frequency voting, - cal and sleep: used for RCLK delay calibration and required for certain platforms for such calibration (as expressed in original commit 4946b3af ("mmc: sdhci-msm: Enable delay circuit calibration clocks")). Only MSM8974pro has these clocks. Relaxing the order fixes dtbs_check warnings: qcom-msm8974pro-fairphone-fp2.dtb: mmc@f9824900: clock-names:3: 'ice' was expected qcom-msm8974pro-fairphone-fp2.dtb: mmc@f9824900: clock-names:4: 'bus' was expected Signed-off-by:

Userspace has currently no way of checking the internal R1 response error bits for some commands. This is a problem for some commands, like RPMB for example. Typically, we may detect that the busy completion has successfully ended, while in fact the card did not complete the requested operation. To fix the problem, let's always poll with CMD13 for these commands and during the polling, let's also aggregate the R1 response bits. Before completing the ioctl request, let's propagate the R1 response bits too. Reviewed-by:

To improve the r/w performance of GL9763E, the current driver inhibits LPM negotiation while the device is active. This prevents a large number of SoCs from suspending, notably x86 systems which commonly use S0ix as the suspend mechanism - for example, Intel Alder Lake and Raptor Lake processors. Failure description: 1. Userspace initiates s2idle suspend (e.g. via writing to /sys/power/state) 2. This switches the runtime_pm device state to active, which disables LPM negotiation, then calls the "regular" suspend callback 3. With LPM negotiation disabled, the bus cannot enter low-power state 4. On a large number of SoCs, if the bus not in a low-power state, S0ix cannot be entered, which in turn prevents the SoC from entering suspend. Fix by re-enabling LPM negotiation in the device's suspend callback. Suggested-by:

Pull tracing fixes from Steven Rostedt: - Fix the "bytes" output of the per_cpu stat file The tracefs/per_cpu/cpu*/stats "bytes" was giving bogus values as the accounting was not accurate. It is suppose to show how many used bytes are still in the ring buffer, but even when the ring buffer was empty it would still show there were bytes used. - Fix a bug in eventfs where reading a dynamic event directory (open) and then creating a dynamic event that goes into that diretory screws up the accounting. On close, the newly created event dentry will get a "dput" without ever having a "dget" done for it. The fix is to allocate an array on dir open to save what dentries were actually "dget" on, and what ones to "dput" on close. * tag 'trace-v6.6-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: eventfs: Remember what dentries were created on dir open ring-buffer: Fix bytes info in per_cpu buffer stats

Pull cxl fixes from Dan Williams: "A collection of regression fixes, bug fixes, and some small cleanups to the Compute Express Link code. The regressions arrived in the v6.5 dev cycle and missed the v6.6 merge window due to my personal absences this cycle. The most important fixes are for scenarios where the CXL subsystem fails to parse valid region configurations established by platform firmware. This is important because agreement between OS and BIOS on the CXL configuration is fundamental to implementing "OS native" error handling, i.e. address translation and component failure identification. Other important fixes are a driver load error when the BIOS lets the Linux PCI core handle AER events, but not CXL memory errors. The other fixex might have end user impact, but for now are only known to trigger in our test/emulation environment. Summary: - Fix multiple scenarios where platform firmware defined regions fail to be assembled by the CXL core. - Fix a spurious driver-load failure on platforms that enable OS native AER, but not OS native CXL error handling. - Fix a regression detecting "poison" commands when "security" commands are also defined. - Fix a cxl_test regression with the move to centralize CXL port register enumeration in the CXL core. - Miscellaneous small fixes and cleanups" * tag 'cxl-fixes-6.6-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl: cxl/acpi: Annotate struct cxl_cxims_data with __counted_by cxl/port: Fix cxl_test register enumeration regression cxl/region: Refactor granularity select in cxl_port_setup_targets() cxl/region: Match auto-discovered region decoders by HPA range cxl/mbox: Fix CEL logic for poison and security commands cxl/pci: Replace host_bridge->native_aer with pcie_aer_is_native() PCI/AER: Export pcie_aer_is_native() cxl/pci: Fix appropriate checking for _OSC while handling CXL RAS registers

When the TSC_AUX MSR is virtualized, the TSC_AUX value is swap type "B" within the VMSA. This means that the guest value is loaded on VMRUN and the host value is restored from the host save area on #VMEXIT. Since the value is restored on #VMEXIT, the KVM user return MSR support for TSC_AUX can be replaced by populating the host save area with the current host value of TSC_AUX. And, since TSC_AUX is not changed by Linux post-boot, the host save area can be set once in svm_hardware_enable(). This eliminates the two WRMSR instructions associated with the user return MSR support. Signed-off-by:

The checks for virtualizing TSC_AUX occur during the vCPU reset processing path. However, at the time of initial vCPU reset processing, when the vCPU is first created, not all of the guest CPUID information has been set. In this case the RDTSCP and RDPID feature support for the guest is not in place and so TSC_AUX virtualization is not established. This continues for each vCPU created for the guest. On the first boot of an AP, vCPU reset processing is executed as a result of an APIC INIT event, this time with all of the guest CPUID information set, resulting in TSC_AUX virtualization being enabled, but only for the APs. The BSP always sees a TSC_AUX value of 0 which probably went unnoticed because, at least for Linux, the BSP TSC_AUX value is 0. Move the TSC_AUX virtualization enablement out of the init_vmcb() path and into the vcpu_after_set_cpuid() path to allow for proper initialization of the support after the guest CPUID information has been set. With the TSC_AUX virtualization support now in the vcpu_set_after_cpuid() path, the intercepts must be either cleared or set based on the guest CPUID input.

svm_recalc_instruction_intercepts() is always called at least once before the vCPU is started, so the setting or clearing of the RDTSCP intercept can be dropped from the TSC_AUX virtualization support.
