a29689e6 - net: handle HAS_IOPORT dependencies

Fri, 05 Apr 2024 11:18:31 +0000

net: handle HAS_IOPORT dependenciesIn a future patch HAS_IOPORT=n will disable inb()/outb() and friends atcompile time. We thus need to add HAS_IOPORT as dependency forthose drivers requiring them. For the DEFXX driver the use of I/Oports is optional and we only need to fence specific code paths. It alsoturns out that with HAS_IOPORT handled explicitly HAMRADIO does not needthe !S390 dependency and successfully builds the bpqether driver.Acked-by: Marc Kleine-Budde Acked-by: Jakub Kicinski Acked-by: Maciej W.

82c944d0 - net: wan: Add framer framework support

Tue, 28 Nov 2023 13:25:30 +0000

net: wan: Add framer framework supportA framer is a component in charge of an E1/T1 line interface.Connected usually to a TDM bus, it converts TDM frames to/from E1/T1frames. It also provides information related to the E1/T1 line.The framer framework provides a set of APIs for the framer drivers(framer provider) to create/destroy a framer and APIs for the framerusers (framer consumer) to obtain a reference to the framer, anduse the framer.This basic implementation provides a framer abstraction for: - power on/off the framer - get the framer status (line state) - be notified on framer status changes - get/set the framer configurationSigned-off-by: Herve Codina Reviewed-by: Christophe Leroy Acked-by: Jakub Kicinski Link: https://lore.kernel.org/r/20231128132534.258459-2-herve.codina@bootlin.comSigned-off-by: Linus Walleij List of files: /linux-6.15/drivers/net/wan/Kconfig

The driver is using virt_to_bus()so it should be updated to a proper DMA API or removed. Giventhe latest "news" entry on the website is from 1999 I'm optingfor the latter.I'm marking the allocated char device major number as [REMOVED],I reckon we can't reuse it in case some SW out there assumes itsCOSA?Signed-off-by: Jakub Kicinski Signed-off-by: David S.

The virt_to_bus() calls discard the volatile keyword.The right thing to do would be to migrate this driver to a modernDMA API but it seems unlikely anyone is actually using it.There had been no fixes or functional changes here sincethe git era begun.Let's remove this driver, there isn't much changing in the APIs,if users come forward we can apologize and revert.Link: https://lore.kernel.org/all/20220321144013.440d7fc0@kicinski-fedora-pc1c0hjn.dhcp.thefacebook.com/Signed-off-by: Jakub Kicinski Acked-by: Arnd Bergmann Acked-by: Thomas Bogendoerfer Signed-off-by: David S.

net: ixp4xx_hss: Check features using sysconIf we access the syscon (expansion bus config registers) using thesyscon regmap instead of relying on direct accessor functions,we do not need to call this static code in the machine(arch/arm/mach-ixp4xx/common.c) which makes things less dependenton custom machine-dependent code.Look up the syscon regmap and handle the error: this will makedeferred probe work with relation to the syscon.Select the syscon in Kconfig and depend on OF so we know thatall we need will be available.Cc: David S.

Sat, 14 Nov 2020 15:09:21 +0000

net: wan: Delete the DLCI / SDLA driversThe DLCI driver (dlci.c) implements the Frame Relay protocol. However,we already have another newer and better implementation of Frame Relayprovided by the HDLC_FR driver (hdlc_fr.c).The DLCI driver's implementation of Frame Relay is used by only onehardware driver in the kernel - the SDLA driver (sdla.c).The SDLA driver provides Frame Relay support for the Sangoma S50x devices.However, the vendor provides their own driver (along with their ownmulti-WAN-protocol implementations including Frame Relay), called WANPIPE.I believe most users of the hardware would use the vendor-provided WANPIPEdriver instead.(The WANPIPE driver was even once in the kernel, but was deleted incommit 8db60bcf3021 ("[WAN]: Remove broken and unmaintained Sangomadrivers.") because the vendor no longer updated the in-kernel WANPIPEdriver.)Cc: Mike McLagan Signed-off-by: Xie He Link: https://lore.kernel.org/r/20201114150921.685594-1-xie.he.0141@gmail.comSigned-off-by: Jakub Kicinski List of files: /linux-6.15/drivers/net/wan/Kconfig

net: x25_asy: Delete the x25_asy driverThis driver transports LAPB (X.25 link layer) frames over TTY links.I can safely say that this driver has no actual user because it wasnot working at all until:commit 8fdcabeac398 ("drivers/net/wan/x25_asy: Fix to make it work")The code in its current state still has problems:1.The uses of "struct x25_asy" in x25_asy_unesc (when receiving) and inx25_asy_write_wakeup (when sending) are not protected by locks againstx25_asy_change_mtu's changing of the transmitting/receiving buffers.Also, all "netif_running" checks in this driver are not protected bylocks against the ndo_stop function.2.The driver stops all TTY read/write when the netif is down.I think this is not right because this may cause the last outgoing framebefore the netif goes down to be incompletely transmitted, and the firstincoming frame after the netif goes up to be incompletely received.And there may also be other problems.I was planning to fix these problems but after recent discussions aboutdeleting other old networking code, I think we may just delete thisdriver, too.Signed-off-by: Xie He Acked-by: Martin Schiller Link: https://lore.kernel.org/r/20201105073434.429307-1-xie.he.0141@gmail.comSigned-off-by: Jakub Kicinski List of files: /linux-6.15/drivers/net/wan/Kconfig

63b903df - net: wan: wanxl: use allow to pass CROSS_COMPILE_M68k for rebuilding firmware

Thu, 26 Mar 2020 05:57:15 +0000

net: wan: wanxl: use allow to pass CROSS_COMPILE_M68k for rebuilding firmwareAs far as I understood from the Kconfig help text, this build rule isused to rebuild the driver firmware, which runs on an old m68k-basedchip. So, you need m68k tools for the firmware rebuild.wanxl.c is a PCI driver, but CONFIG_M68K does not select CONFIG_HAVE_PCI.So, you cannot enable CONFIG_WANXL_BUILD_FIRMWARE for ARCH=m68k. In otherwords, ifeq ($(ARCH),m68k) is false here.I am keeping the dead code for now, but rebuilding the firmware requires'as68k' and 'ld68k', which I do not have in hand.Instead, the kernel.org m68k GCC [1] successfully built it.Allowing a user to pass in CROSS_COMPILE_M68K= is handier.[1] https://mirrors.edge.kernel.org/pub/tools/crosstool/files/bin/x86_64/9.2.0/x86_64-gcc-9.2.0-nolibc-m68k-linux.tar.xzSuggested-by: Geert Uytterhoeven Signed-off-by: Masahiro Yamada List of files: /linux-6.15/drivers/net/wan/Kconfig

net/wan: dscc4: remove broken dscc4 driverUsing static analysis, I discovered that the "dpriv->pci_priv->pdev"pointer is always NULL. This pointer was supposed to be initializedduring probe and is essential for the driver to work. It would be easyto add a "ppriv->pdev = pdev;" to dscc4_found1() but this driver hasbeen broken since before we started using git and no one has complainedso probably we should just remove it.Signed-off-by: Dan Carpenter Acked-by: Francois Romieu Signed-off-by: David S.
