commit bd0193c88abb282aaef3f1a56e6f2fdf0366c216
Author: Samuel Thibault <samuel.thiba...@ens-lyon.org>
Date: Sun Nov 10 17:04:12 2019 +0100
Fix build warning
* ddb/db_command.c: Include <ipc/mach_port.h>.
commit b688ffc29a685d1332e080798c914f26ae5c63c0
Author: Samuel Thibault <samuel.thiba...@ens-lyon.org>
Date: Sun Nov 10 16:52:15 2019 +0100
Run interrupt handlers at spl7
* i386/i386at/interrupt.S (interrupt): Call spl7 instead of the
intpri-provided one.
commit 1d34167488e56e36ad702627b17be7ac18a9db9c
Author: Damien Zammit <dam...@zamaudio.com>
Date: Sun Nov 10 16:27:42 2019 +0100
simplify interrupt handling
We have removed spl levels, now remove the machinery to manage different
PIC masks according to levels. Only keep machinery to disable interrupts
whatever the level.
* i386/i386/pic.c (pic_mask): Remove array.
(picinit): Do not form PIC mask. Set initial PIC mask to 0.
(form_pic_mask): Remove function.
* i386/i386/pic.h (form_pic_mask, pic_mask): Remove declarations.
* i386/i386/spl.S (SETMASK): Remove macro.
(XEN_SETMASK): Add macro, containing the Xen version of SETMASK.
(spl0, splx_cli, spl) [MACH_XEN]: Call XEN_SETMASK instead of SETMASK.
* i386/i386/pit.c (clkstart): Do not call form_pic_mask.
* i386/i386at/autoconf.c (take_dev_irq, take_ctlr_irq): Likewise.
* i386/i386at/kd_mouse.c (kd_mouse_open, kd_mouse_close): Likewise.
* linux/dev/arch/i386/kernel/irq.c (mask_irq, unmask_irq): Directly update
curr_pic_mask without using pic_mask array.
(init_IRQ, restore_IRQ): do not call form_pic_mask.
* linux/dev/include/asm-i386/system.h: Include <i386/ipl.h>.
(__save_flags, __restore_flags): Use curr_ipl and splx instead of
hardware flags.
* linux/dev/init/main.c (linux_init): Do not call cli.
* linux/dev/kernel/sched.c (linux_timer_intr): Do not use pic_mask.
* linux/src/drivers/block/ide.c (try_to_identify): Disable irq probing.
* linux/src/drivers/scsi/NCR53c406a.c (NCR53c406a_detect): Disable irq
probing.
