char: pcmcia: remove all the drivers

2023-03-09T16:30:27+00:00

These char PCMCIA drivers are buggy[1] and receive only minimal care. It was concluded[2], that we should try to remove most pcmcia drivers completely. Let's start with these char broken one. Note that I also removed a UAPI header: include/uapi/linux/cm4000_cs.h. I found only coccinelle tests mentioning some ioctl constants from that file. But they are not actually used. Anyway, should someone complain, we may reintroduce the header (or its parts).

tty: ipwireless: move Kconfig entry to tty

2023-03-09T16:30:27+00:00

The ipwireless' Kconfig entry is currently sitting in char/pcmcia. But the driver is in tty/. So move the entry to tty/ too. First, it makes sense to have the entry along the driver. Second, whole char/pcmcia is about to pass away.

char/pcmcia: add scr24x_cs chip card interface driver

2016-11-10T16:03:36+00:00

This implements only the very basic protocol "Mode A", just to make the device functional. Patches to implement "Mode C" that uses better bulking and is interrupt-driver may follow. The device essentially speaks the same protocol as USB CCID devices do over the bulk endpoints. The driver exchanges the command submissions and responses over a plain read()/write() interface, compatible with legacy OpenCT's pcmcia_block driver. Patches for the newer CCID driver are available: https://github.com/lkundrak/CCID/tree/lr/pcmcia_block Signed-off-by: Lubomir Rintel Signed-off-by: Greg Kroah-Hartman

Finally eradicate CONFIG_HOTPLUG

2013-06-03T21:20:18+00:00

Ever since commit 45f035ab9b8f ("CONFIG_HOTPLUG should be always on"), it has been basically impossible to build a kernel with CONFIG_HOTPLUG turned off. Remove all the remaining references to it.

tty: Added a CONFIG_TTY option to allow removal of TTY

2013-01-19T00:15:27+00:00

The option allows you to remove TTY and compile without errors. This saves 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 on TTY" to various serial devices and similar drivers that require the TTY layer. Ideally, these dependencies would occur on a common intermediate symbol 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 by removing TTY. The list is filtered to not show removed entries with awk '$3 != "-"' as the list was very long. add/remove: 0/226 grow/shrink: 2/14 up/down: 6/-35356 (-35350) function old new delta chr_dev_init 166 170 +4 allow_signal 80 82 +2 static.__warned 143 142 -1 disallow_signal 63 62 -1 __set_special_pids 95 94 -1 unregister_console 126 121 -5 start_kernel 546 541 -5 register_console 593 588 -5 copy_from_user 45 40 -5 sys_setsid 128 120 -8 sys_vhangup 32 19 -13 do_exit 1543 1526 -17 bitmap_zero 60 40 -20 arch_local_irq_save 137 117 -20 release_task 674 652 -22 static.spin_unlock_irqrestore 308 260 -48 Signed-off-by: Joe Millenbach Reviewed-by: Jamey Sharp Reviewed-by: Josh Triplett Signed-off-by: Greg Kroah-Hartman

pcmcia: ipwireless depends on NETDEVICES

2008-02-14T00:21:20+00:00

ipwireless (added by 099dc4fb62653f6019d78db55fba7a18ef02d65b) is clearly a net device: drivers/built-in.o: In function `ipwireless_ppp_start_xmit': /home/pmundt/devel/git/sh-2.6.25/drivers/char/pcmcia/ipwireless/network.c:165: undefined reference to `skb_under_panic' /home/pmundt/devel/git/sh-2.6.25/drivers/char/pcmcia/ipwireless/network.c:165: undefined reference to `kfree_skb' drivers/built-in.o: In function `ipwireless_network_packet_received': /home/pmundt/devel/git/sh-2.6.25/drivers/char/pcmcia/ipwireless/network.c:377: undefined reference to `__alloc_skb' /home/pmundt/devel/git/sh-2.6.25/drivers/char/pcmcia/ipwireless/network.c:377: undefined reference to `skb_over_panic' drivers/built-in.o: In function `ppp_shutdown_interface': /home/pmundt/devel/git/sh-2.6.25/drivers/net/ppp_generic.c:2517: undefined reference to `unregister_netdev' /home/pmundt/devel/git/sh-2.6.25/drivers/net/ppp_generic.c:2517: undefined reference to `free_netdev' [ ... and many more ... ] select strikes again. ipwireless selects PPP which in turn tries to select SLHC, both of which are technically "protected" by an if NETDEVICES in drivers/net/Kconfig. This leads to .config hilarity, with net suddenly ending up in the SCSI menu: # # SCSI device support # # CONFIG_SCSI_DMA is not set # CONFIG_SCSI_NETLINK is not set CONFIG_PPP=y # CONFIG_PHONE is not set Curiously the SLHC select from PPP doesn't seem to happen, as there's no CONFIG_SLHC=y (only CONFIG_PPP=y gets set) -- Kconfig bug?

ipwireless: driver for PC Card 3G/UMTS modem

2008-02-08T01:19:49+00:00

The device is manufactured by IPWireless. In some countries (for example Czech Republic, T-Mobile ISP) this card is shipped for service called UMTS 4G. It's a piece of PCMCIA "4G" UMTS PPP networking hardware that presents itself as a serial character device (i.e. looks like usual modem to userspace, accepts AT commands, etc).
