TTY: switch tty_schedule_flip

2013-01-16T06:43:15Z

Now, we start converting tty buffer functions to actually use tty_port. This will allow us to get rid of the need of tty in many call sites. Only tty_port will needed and hence no more tty_port_tty_get in those paths. This is the last one: tty_schedule_flip Signed-off-by: Jiri Slaby Signed-off-by: Greg Kroah-Hartman

TTY: switch tty_insert_flip_char

2013-01-16T06:21:36Z

Now, we start converting tty buffer functions to actually use tty_port. This will allow us to get rid of the need of tty in many call sites. Only tty_port will needed and hence no more tty_port_tty_get in those paths. tty_insert_flip_char is the next one to proceed. This one is used all over the code, so the patch is huge.

TTY: call tty_port_destroy in the rest of drivers

2012-11-16T01:20:58Z

After commit "TTY: move tty buffers to tty_port", the tty buffers are not freed in some drivers. This is because tty_port_destructor is not called whenever a tty_port is freed. This was an assumption I counted with but was unfortunately untrue. So fix the drivers to fulfil this assumption. To be sure, the TTY buffers (and later some stuff) are gone along with the tty_port, we have to call tty_port_destroy at tear-down places. This is mostly where the structure containing a tty_port is freed. This patch does exactly that -- put tty_port_destroy at those places. Signed-off-by: Jiri Slaby Signed-off-by: Greg Kroah-Hartman

TTY: use tty_port_link_device

2012-08-13T23:50:19Z

So now for those drivers that can use neither tty_port_install nor tty_port_register_driver but still have tty_port available before tty_register_driver we use newly added tty_port_link_device. The rest of the drivers that still do not provide tty_struct <-> tty_port link will have to be converted to implement tty->ops->install.

TTY: srmcons, convert to use tty_port

2012-03-08T19:42:21Z

This is needed because the tty buffer will become a tty_port member later. That will help us to wipe out most of the races and checks for the tty pointer in hot paths. Signed-off-by: Jiri Slaby Cc: Richard Henderson Cc: Ivan Kokshaysky Cc: Matt Turner Signed-off-by: Greg Kroah-Hartman

ALPHA: srmcons, fix racy singleton structure

2012-03-08T19:42:21Z

The test and the assignment were racy. Make it really a singleton. This is achieved by one global variable initialized at the module init. Signed-off-by: Jiri Slaby Cc: Richard Henderson Cc: Ivan Kokshaysky Cc: Matt Turner Signed-off-by: Greg Kroah-Hartman

ALPHA: srmcons, use timer functions

2012-03-08T19:42:21Z

It makes the code more readable. We move the setup to the allocation location because we need to initialize timers only once. Signed-off-by: Jiri Slaby Cc: Richard Henderson Cc: Ivan Kokshaysky Cc: Matt Turner Signed-off-by: Greg Kroah-Hartman

alpha: fix trivial section mismatch warnings

2007-07-16T16:05:37Z

Fix the following section mismatch warnings: WARNING: arch/alpha/kernel/built-in.o(.text+0x7c78): Section mismatch: reference to .init.text:init_rtc_irq (between 'common_init_rtc' and 'timer_interrupt') WARNING: arch/alpha/kernel/built-in.o(.text+0x7c7c): Section mismatch: reference to .init.text:init_rtc_irq (between 'common_init_rtc' and 'timer_interrupt') WARNING: arch/alpha/kernel/built-in.o(.data+0x2c30): Section mismatch: reference to .init.text:srm_console_setup (between 'srmcons' and 'tsunami_pci_ops') In all three cases functions marked __init was called outside __init context. So the fix was to just drop the __init attribute. Signed-off-by: Sam Ravnborg Cc: Meelis Roos Cc: Ivan Kokshaysky Cc: Richard Henderson Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

Fixes and cleanups for earlyprintk aka boot console

2007-05-08T18:15:04Z

The console subsystem already has an idea of a boot console, using the CON_BOOT flag. The implementation has some flaws though. The major problem is that presence of a boot console makes register_console() ignore any other console devices (unless explicitly specified on the kernel command line). This patch fixes the console selection code to *not* consider a boot console a full-featured one, so the first non-boot console registering will become the default console instead. This way the unregister call for the boot console in the register_console() function actually triggers and the handover from the boot console to the real console device works smoothly. Added a printk for the handover, so you know which console device the output goes to when the boot console stops printing messages. The disable_early_printk() call is obsolete with that patch, explicitly disabling the early console isn't needed any more as it works automagically with that patch. I've walked through the tree, dropped all disable_early_printk() instances found below arch/ and tagged the consoles with CON_BOOT if needed. The code is tested on x86, sh (thanks to Paul) and mips (thanks to Ralf). Changes to last version: Rediffed against -rc3, adapted to mips cleanups by Ralf, fixed "udbg-immortal" cmd line arg on powerpc.
