[PATCH 2/6] drm/nouveau: Unbreak nv50_mstc->best_encoder()

by Lyude Paul

As mentioned in the previous commit, we currently prevent new modesets on recently-removed MST connectors by returning no encoder from our ->best_encoder() callback once the MST port has disappeared. This is wrong however, because it prevents legacy modesetting users from being able to disable CRTCs on MST connectors after the connector's respective topology has disappeared. So, fix this by instead using the new drm_dp_mst_connector_atomic_check() helper instead while always returning a valid encoder from ->best_encoder().

[PATCH v5 0/7] mm: Merge hmm into devm_memremap_pages, mark GPL-only

by Dan Williams

Changes since v4 [1]: * Rebase on v4.19-rc3 * Update changelogs and cover letter [1]: https://lkml.org/lkml/2018/7/11/14 --- Hi Andrew, Back from vacation and this series is still top of mind. devm_memremap_pages() is a facility that can create struct page entries for any arbitrary range and give drivers the ability to subvert core aspects of page management. It, and anything derived from it (e.g. hmm, pcip2p, etc...), is an EXPORT_SYMBOL_GPL() interface. I see that commit 31c5bda3a656 "mm: fix exports that inadvertently make put_page() EXPORT_SYMBOL_GPL" was merged ahead of this series to relieve some of the pressure from innocent consumers of put_page(), but now we need this series to address *producers* of device pages. More details and justification in the changelogs. The 0day infrastructure has reported success across 182 configs and this survives the libnvdimm unit test suite. Aside from the controversial bits the diffstat is compelling at: 7 files changed, 138 insertions(+), 328 deletions(-). Note that the series has some minor collisions with Alex's recent series to improve devm_memremap_pages() scalability [2]. So, whichever you take first the other will need a minor rebase.

[PATCH v3] tpm: Restore functionality to xen vtpm driver.

by Boris Ostrovsky

From: "Dr. Greg Wettstein" <greg(a)wind.enjellic.com> Functionality of the xen-tpmfront driver was lost secondary to the introduction of xenbus multi-page support in commit ccc9d90a9a8b ("xenbus_client: Extend interface to support multi-page ring"). In this commit pointer to location of where the shared page address is stored was being passed to the xenbus_grant_ring() function rather then the address of the shared page itself. This resulted in a situation where the driver would attach to the vtpm-stubdom but any attempt to send a command to the stub domain would timeout. A diagnostic finding for this regression is the following error message being generated when the xen-tpmfront driver probes for a device: <3>vtpm vtpm-0: tpm_transmit: tpm_send: error -62 <3>vtpm vtpm-0: A TPM error (-62) occurred attempting to determine the timeouts This fix is relevant to all kernels from 4.1 forward which is the release in which multi-page xenbus support was introduced. Daniel De Graaf formulated the fix by code inspection after the regression point was located.

patch "serial: 8250: Fix clearing FIFOs in RS485 mode again" added to tty-next

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled serial: 8250: Fix clearing FIFOs in RS485 mode again 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-next 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 also be merged in the next major kernel release during the merge window. If you have any questions about this process, please let me know. >From f6aa5beb45be27968a4df90176ca36dfc4363d37 Mon Sep 17 00:00:00 2001 From: Marek Vasut <marex(a)denx.de> Date: Mon, 3 Sep 2018 02:44:52 +0200 Subject: serial: 8250: Fix clearing FIFOs in RS485 mode again The 8250 FIFOs indeed need to be cleared after stopping transmission in RS485 mode without SER_RS485_RX_DURING_TX flag set. But there are two problems with the approach taken by the previous patch from Fixes tag. First, serial8250_clear_fifos() should clear fifos, but what it really does is it enables the FIFOs unconditionally if present, clears them and then sets the FCR register to zero, which effectively disables the FIFOs. In case the FIFO is disabled, enabling it and clearing it makes no sense and in fact can trigger misbehavior of the 8250 core. Moreover, the FCR register may contain other FIFO configuration bits which may not be writable unconditionally and writing them incorrectly can trigger misbehavior of the 8250 core too. (ie. AM335x UART swallows the first byte and retransmits the last byte twice because of this FCR write). Second, serial8250_clear_and_reinit_fifos() completely reloads the FCR, but what really has to happen at the end of the RS485 transmission is clearing of the FIFOs and nothing else. This patch repairs serial8250_clear_fifos() so that it really only clears the FIFOs by operating on FCR[2:1] bits and leaves all the other bits alone. It also undoes serial8250_clear_and_reinit_fifos() from __do_stop_tx_rs485() as serial8250_clear_fifos() is sufficient.

patch "serial: cpm_uart: return immediately from console poll" 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: cpm_uart: return immediately from console poll 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 be28c1e3ca29887e207f0cbcd294cefe5074bab6 Mon Sep 17 00:00:00 2001 From: Christophe Leroy <christophe.leroy(a)c-s.fr> Date: Fri, 14 Sep 2018 10:32:50 +0000 Subject: serial: cpm_uart: return immediately from console poll kgdb expects poll function to return immediately and returning NO_POLL_CHAR when no character is available.

It's apparently running in 8-bit mode, but it makes userspace believe it's in 5-bit mode. That makes tcsetattr with CS8 incorrectly fail, breaking e.g. getty from busybox, thus the login shell on ttyMVx. Fix by hard-wiring CS8 into c_cflag.
