m68k: atari: Fix TT bootup freeze / unexpected (SCU) interrupt messages

2024-08-19T03:31:57Z

[ Upstream commit f70065a9fd988983b2c693631b801f25a615fc04 ] Avoid freeze on Atari TT / MegaSTe boot with continuous messages of: unexpected interrupt from 112 Which was due to VBL interrupt being enabled in SCU sys mask, but there being no handler for that any more. (Bug and fix were first verified on real Atari TT HW by Christian, this patch later on in Hatari emulator.)

m68k: Call timer_interrupt() with interrupts disabled

2020-01-27T13:51:23Z

[ Upstream commit 1efdd4bd254311498123a15fa0acd565f454da97 ] Some platforms execute their timer handler with the interrupt priority level set below 6. That means the handler could be interrupted by another driver and this could lead to re-entry of the timer core. Avoid this by use of local_irq_save/restore for timer interrupt dispatch. This provides mutual exclusion around the timer interrupt flag access which is needed later in this series for the clocksource conversion.

m68k: Remove unused set_clock_mmss() helpers

2018-07-29T08:48:18Z

Commit 397ac99c6cef ("m68k: remove dead timer code") removed set_rtc_mmss() because it was unused in 2012. However, this was itself the only user of the mach_set_clock_mmss() callback and the many implementations of that callback, which are equally unused. This removes all of those as well.

m68k/atari: Modernize printing of kernel messages

2017-02-12T09:36:49Z

- Convert from printk() to pr_*(), - Add missing continuations, to fix user-visible breakage, - Drop useless WARNING prefix, - Move trailing spaces to start of continuations. Note that the "Keyboard overrun" message will now only be generated when the kernel has been compiled for debugging. Fixes: 4bcc595ccd80decb ("printk: reinstate KERN_CONT for printing continuation lines") Signed-off-by: Geert Uytterhoeven

m68k/atari: Use seq_puts() in atari_get_hardware_list()

2016-12-09T07:52:29Z

A string which did not contain a data format specification should be put into a sequence. Thus use the corresponding function "seq_puts". This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring Signed-off-by: Geert Uytterhoeven

m68k/atari: Remove obsolete IRQ_TYPE_*

2015-01-15T12:44:51Z

IRQ_TYPE_SLOW, IRQ_TYPE_FAST, and IRQ_TYPE_PRIO are no longer used by the Atari platform interrupt code since commit 734085651c9b80aa ("[PATCH] m68k: convert atari irq code") in v2.6.18-rc1, so drop them. Note that their values have been reused for different purposes (IRQ_TYPE_NONE, IRQ_TYPE_EDGE_RISING, and IRQ_TYPE_EDGE_FALLING) since commit 6a6de9ef5850d063 ("[PATCH] genirq: core") in v2.6.18-rc1.

m68k/atari: Remove obsolete keyboard_tasklet scheduling

2015-01-13T08:44:17Z

If CONFIG_VT=n: arch/m68k/atari/built-in.o: In function `atari_keyboard_interrupt': atakeyb.c:(.text+0x1846): undefined reference to `keyboard_tasklet' atakeyb.c:(.text+0x1852): undefined reference to `keyboard_tasklet' I think the keyboard_tasklet scheduling is no longer needed, as I believe it's handled by drivers/tty/vt/keyboard.c based on events received from the input subsystem. So just remove it. Signed-off-by: Geert Uytterhoeven Tested-by: Michael Schmitz

m68k/atari: atakeyb.c - Remove some unused functions

2015-01-11T10:38:44Z

Remove some functions that are not used anywhere: atari_kbd_leds() ikbd_exec() ikbd_mem_read() ikbd_mem_write() ikbd_clock_get() ikbd_clock_set() ikbd_pause() ikbd_resume() This was partially found by using a static code analysis program called cppcheck.
