[tip: x86/fpu] x86/fpu/xstate: Fix XSTATE_WARN_ON() to emit relevant diagnostics

by tip-bot2 for Andrew Cooper

The following commit has been merged into the x86/fpu branch of tip: Commit-ID: 48280042f2c6e3ac2cfb1d8b752ab4a7e0baea24 Gitweb: https://git.kernel.org/tip/48280042f2c6e3ac2cfb1d8b752ab4a7e0baea24 Author: Andrew Cooper <andrew.cooper3(a)citrix.com> AuthorDate: Wed, 10 Aug 2022 23:19:09 +01:00 Committer: Borislav Petkov <bp(a)suse.de> CommitterDate: Wed, 09 Nov 2022 13:28:31 +01:00 x86/fpu/xstate: Fix XSTATE_WARN_ON() to emit relevant diagnostics "XSAVE consistency problem" has been reported under Xen, but that's the extent of my divination skills. Modify XSTATE_WARN_ON() to force the caller to provide relevant diagnostic information, and modify each caller suitably. For check_xstate_against_struct(), this removes a double WARN() where one will do perfectly fine. CC stable as this has been wonky debugging for 7 years and it is good to have there too.

[PATCH v2] usb: add NO_LPM quirk for Realforce 87U Keyboard

by Nicolas Dumazet

Before adding this quirk, this (mechanical keyboard) device would not be recognized, logging: new full-speed USB device number 56 using xhci_hcd unable to read config index 0 descriptor/start: -32 chopping to 0 config(s) It would take dozens of plugging/unpuggling cycles for the keyboard to be recognized. Keyboard seems to simply work after applying this quirk. This issue had been reported by users in two places already ([1], [2]) but nobody tried upstreaming a patch yet. After testing I believe their suggested fix (DELAY_INIT + NO_LPM + DEVICE_QUALIFIER) was probably a little overkill. I assume this particular combination was tested because it had been previously suggested in [3], but only NO_LPM seems sufficient for this device.

patch "serial: 8250: Flush DMA Rx on RLSI" added to tty-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled serial: 8250: Flush DMA Rx on RLSI to my tty git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty.git in the tty-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. From 1980860e0c8299316cddaf0992dd9e1258ec9d88 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ilpo=20J=C3=A4rvinen?= <ilpo.jarvinen(a)linux.intel.com> Date: Tue, 8 Nov 2022 14:19:52 +0200 Subject: serial: 8250: Flush DMA Rx on RLSI MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Returning true from handle_rx_dma() without flushing DMA first creates a data ordering hazard. If DMA Rx has handled any character at the point when RLSI occurs, the non-DMA path handles any pending characters jumping them ahead of those characters that are pending under DMA.

patch "serial: 8250_lpss: Use 16B DMA burst with Elkhart Lake" added to tty-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled serial: 8250_lpss: Use 16B DMA burst with Elkhart Lake to my tty git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty.git in the tty-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know.

This makes the bus use more efficient and works around an issue which occurs with the previously used 1B. The fix was initially developed by Srikanth Thokala and Aman Kumar. This together with the previous config change is the cleaned up version of the original fix.

patch "serial: 8250: Fall back to non-DMA Rx if IIR_RDI occurs" added to tty-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled serial: 8250: Fall back to non-DMA Rx if IIR_RDI occurs to my tty git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty.git in the tty-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)

Since IIR_RDI has higher priority than IIR_RX_TIMEOUT, this causes the Rx to hang into interrupt loop. The problem seems to occur at least with some combinations of small-sized transfers (I've reproduced the problem on Elkhart Lake PSE UARTs). If there's already an on-going Rx DMA and IIR_RDI triggers, fall graciously back to non-DMA Rx. That is, behave as if IIR_RX_TIMEOUT had occurred. 8250_omap already considers IIR_RDI similar to this change so its nothing unheard of.
