2008-10-13stallion: Use krefsAlan Cox
Use tty_port_init and krefs in the stallion drivers to protect us from devices going away underneath us.

2008-07-25hvc_console: rework setup to replace irq functions with callbacksChristian Borntraeger
This patch tries to change hvc_console to not use request_irq/free_irq if the backend does not use irqs. This allows virtio_console to use hvc_console without having a linker reference to request_irq/free_irq. In addition, together with patch 2/3 it improves the performance for virtio console input. (an earlier version of this patch was tested by Yajin on lguest) The irq specific code is moved to hvc_irq.c and selected by the drivers that use irqs (System p, System i, XEN). I replaced "int irq" with the opaque "int data". The request_irq and free_irq calls are replaced with notifier_add and notifier_del. I have also changed the code a bit to call the notifier_add and notifier_del inside the spinlock area as the callbacks are found via hp->ops. Changes since last version: o remove ifdef o reintroduce "irq_requested" as "notified" o cleanups, sparse.. I did not move the timer based polling into a separate polling scheme. I played with several variants, but it seems we need to sleep/schedule in a thread even for irq based consoles, as there are throttleing and buffer size constraints. I also kept hvc_struct defined in hvc_console.h so that hvc_irq.c can access the irq_requested element. Feedback is appreciated. virtio_console is currently the only available console for kvm on s390. I plan to push this change as soon as all affected parties agree on it. I would love to get test results from System p, Xen etc. Signed-off-by: Christian Borntraeger <borntraeger@de.ibm.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

2008-04-28rtc: avoid legacy drivers with generic frameworkDavid Brownell
Kconfig tweaks to help reduce RTC configuration bugs, by avoiding legacy RTC drivers when the generic RTC framework is enabled: - If rtc-cmos is selected, disable the legacy rtc driver; - When using generic RTC on x86, enable rtc-cmos by default; - In the old "chardev RTC" section of Kconfig, add a comment warning people off these (seven) legacy RTC drivers when the generic framework is in use. People can still use the legacy drivers if they want (or need) to. This doesn't fix the broken dependencies for the legacy "CMOS" RTC driver. Ideally it would be a full list of platforms where it works, not a partial list of ones where it won't. Or better yet, it would depend on a "HAVE_CMOS_RTC" flag defined by various platforms ... surely there's a Kconfig style guideline lurking there.

2008-02-06[POWERPC] Xilinx: hwicap driverStephen Neuendorffer
This includes code for new fifo-based xps_hwicap in addition to the older opb_hwicap, which has a significantly different interface. The common code between the two drivers is largely shared. Significant differences exists between this driver and what is supported in the EDK drivers. In particular, most of the architecture-specific code for reconfiguring individual FPGA resources has been removed. This functionality is likely better provided in a user-space support library. In addition, read and write access is supported. In addition, although the xps_hwicap cores support interrupt-driver mode, this driver only supports polled operation, in order to make the code simpler, and since the interrupt processing overhead is likely to slow down the throughput under Linux.

2007-07-18zs: move to the serial subsystemMaciej W. Rozycki
This is a reimplementation of the zs driver for the serial subsystem. Any resemblance to the old driver is purely coincidential. ;-) I do hope I got the handling of modem lines right -- better do not tackle me about the issue unless you feel too good... Any users of the old driver: please note the numbers of the serial lines have now been swapped, i.e. ttyS0 <-> ttyS1 and ttyS2 <-> ttyS3. It has to do with the modem lines mentioned above; basically the port A in a given chip has to be initialised before the port B if you want to use the latter as the serial console (which is usually the case), as operations on modem lines of the serial line associated with the port B access both ports (see the comment at the top of the driver for the details of wiring used). Please update your scripts. This is also the reason each SCC now requests an IRQ once only (as seen in "/proc/interrupts") -- the handler takes care of both ports at once as the line associated with the port B has to take status update interrupts from both ports (and yet the line of the port A takes its own for itself too). The old driver never got it right... Signed-off-by: Maciej W.
