ca75bcf0 - net: remove the caif_hsi driver

net: remove the caif_hsi driverThe caif_hsi driver relies on a cfhsi_get_ops symbol using symbol_get,but this symbol is not provided anywhere in the kernel tree.

f2bf88c4 - net: caif: Remove unused caif SPI driver

Tue, 29 Sep 2020 20:25:11 +0000

net: caif: Remove unused caif SPI driverWhile chasing in_interrupt() (ab)use in drivers it turned out that thecaif_spi driver has never been in use since the driver was merged 10 yearsago. There never was any matching code which provides a platform device.The driver has not seen any update (asided of treewide changes andcleanups) since 8 years and the maintainers vanished from the planet.So analysing the potential contexts and the (in)correctness ofin_interrupt() usage is just a pointless exercise.Remove the cruft.Signed-off-by: Thomas Gleixner Signed-off-by: David S.

a7f7f624 - treewide: replace '---help---' in Kconfig files with 'help'

Sat, 13 Jun 2020 16:50:22 +0000

treewide: replace '---help---' in Kconfig files with 'help'Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over'---help---'"), the number of '---help---' has been graduallydecreasing, but there are still more than 2400 instances.This commit finishes the conversion. While I touched the lines,I also fixed the indentation.There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---'In order to convert all of them to 1 tab + 'help', I ran thefollowing commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'Signed-off-by: Masahiro Yamada List of files: /linux-6.15/drivers/net/caif/Kconfig

d085eb8c - vhost: disable for OABI

Mon, 06 Apr 2020 12:12:47 +0000

vhost: disable for OABIvhost is currently broken on the some ARM configs.The reason is that the ring element addresses are passed betweencomponents with different alignments assumptions. Thus, ifguest selects a pointer and host then gets and dereferencesit, then alignment assumed by the host's compiler might begreater than the actual alignment of the pointer.compiler on the host from assuming pointer is aligned.This actually triggers on ARM with -mabi=apcs-gnu - which is adeprecated configuration. With this OABI, compiler assumes thatall structures are 4 byte aligned - which is stronger thanvirtio guarantees for available and used rings, which aremerely 2 bytes. Thus a guest without -mabi=apcs-gnu runningon top of host with -mabi=apcs-gnu will be broken.The correct fix is to force alignment of structures - howeverthat is an intrusive fix that's best deferred until the next release.We didn't previously support such ancient systems at all - this surfacedafter vdpa support prompted removing dependency of vhost onVIRTULIZATION. So for now, let's just add something along the lines of depends on !ARM || AEABIto the virtio Kconfig declaration, and add a comment that it has to dowith struct member alignment.Note: we can't make VHOST and VHOST_RING themselves havea dependency since these are selected. Add a new symbol for that.We should be able to drop this dependency down the road.Fixes: 20c384f1ea1a0bc7 ("vhost: refine vhost and vringh kconfig")Suggested-by: Ard Biesheuvel Suggested-by: Richard Earnshaw Signed-off-by: Michael S.

20c384f1 - vhost: refine vhost and vringh kconfig

Thu, 26 Mar 2020 14:01:17 +0000

vhost: refine vhost and vringh kconfigCurrently, CONFIG_VHOST depends on CONFIG_VIRTUALIZATION. But vhost isnot necessarily for VM since it's a generic userspace and kernelcommunication protocol. Such dependency may prevent archs withoutvirtualization support from using vhost.To solve this, a dedicated vhost menu is created under drivers soCONIFG_VHOST can be decoupled out of CONFIG_VIRTUALIZATION.While at it, also squash Kconfig.vringh into vhost Kconfig file. Thisavoids the trick of conditional inclusion from VOP or CAIF. Then itwill be easier to introduce new vringh users and common dependency forboth vringh and vhost.Signed-off-by: Jason Wang Link: https://lore.kernel.org/r/20200326140125.19794-2-jasowang@redhat.comSigned-off-by: Michael S.

caif_virtio: Introduce caif over virtioAdd the CAIF Virtio shared memory driver for talkingto a modem.This CAIF Link layer communicates to the modem overshared memory. It is implemented as a virtio_driver.The underlying virtio device is managed by the remoteprocframework. The Virtio queue is used for transmitting datato the modem, and the new vringh is used for receiving data.Genalloc is used for managing the shared memory used for TXdata. The default dma-alloc-coherent allocator can onlyallocate whole pages, and this wastes too much shared memory.Flow control is implemented by stopping the TX-queues if thevirtio queues go full or we run out of memory. Queued arereopened when queues are below the watermark.NAPI is used in RX path, and a dedicated tasklet is usedfor releasing TX buffers.Signed-off-by: Erwan Yvin Acked-by: David S.

Thissaves space on systems that won't support TTY interfaces anyway.bloat-o-meter output is below.The bulk of this patch consists of Kconfig changes adding "depends onTTY" to various serial devices and similar drivers that require the TTYlayer. Ideally, these dependencies would occur on a common intermediatesymbol such as SERIO, but most drivers "select SERIO" rather than"depends on SERIO", and "select" does not respect dependencies.bloat-o-meter output comparing our previous minimal to new minimal byremoving TTY.
