* m68k: Remove unused set_clock_mmss() helpersArnd Bergmann2018-07-292-68/+0
| | | | | | | | | | | | | 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.

* atari_scsi: Fix atari_scsi deadlocks on FalconFinn Thain2014-11-201-21/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Don't disable irqs when waiting for the ST DMA "lock"; its release may require an interrupt. Introduce stdma_try_lock() for use in soft irq context. atari_scsi now tells the SCSI mid-layer to defer queueing a command if the ST DMA lock is not available, as per Michael's patch: http://marc.info/?l=linux-m68k&m=139095335824863&w=2 The falcon_got_lock variable is race prone: we can't disable IRQs while waiting to acquire the lock, so after acquiring it there must be some interval during which falcon_got_lock remains false. Introduce stdma_is_locked_by() to replace falcon_got_lock. The falcon_got_lock tests in the EH handlers are incorrect these days. It can happen that an EH handler is called after a command completes normally. Remove these checks along with falcon_got_lock. Also remove the complicated and racy fairness wait queues. If fairness is an issue (when SCSI competes with IDE for the ST DMA interrupt), the solution is likely to be a lower value for host->can_queue.

* m68k/atari - stram: alloc ST-RAM pool even if kernel not in ST-RAMMichael Schmitz2014-05-261-17/+54
| | | | | | | | | | | | | | | | | | | | | | | | | With the kernel loaded to FastRAM (TT-RAM), none of the ST-RAM address range is mapped by init_mem, and ST-RAM is not accessible through the normal allocation pathways as a result. Implement ST-RAM pool allocation to be based on physical addresses always (it already was when the kernel was loaded in ST-RAM). Return kernel virtual addresses as per normal. The current test for the kernel residing in ST-RAM always returns true. Use the bootinfo memory chunk order instead - with the kernel in FastRAM, ST-RAM (phys. 0x0) is not the first chunk. In case the kernel is running from FastRAM, delay mapping of ST-RAM pool until after mem_init. Provide helper functions for those users of ST-RAM that need to be aware of the backing physical addresses. Kudos to Geert for his hints on getting this started.

* m68k/irq - Use polled IRQ flag for MFP timer cascaded interruptsMichael Schmitz2014-01-131-0/+3
| | | | | | | | | | | | | | | | | | | | | Some Atari hardware has no capacity to raise interrupts (e.g. network or USB adapter hardware attached via ROM port). The driver interrupt routine is called from a timer interrupt (timer D) in these cases, using chained device specific pseudo interrupts (IRQ_MFP_TIMER1 ff.) These interrupts will more often than not, return IRQ_NONE as there is not always work for the device handler when called. Too many unhandled interrupts will result in the interrupt being disabled by the stuck interrupt watchdog. As preferred option to flag interrupts as needing exclusion from the watchdog mechanism, tglx added the IRQ_IS_POLLED flag for use in such a case. Currently, two interrupts need to use this flag. Add more users as needed. Signed-off-by: Michael Schmitz <schmitz@debian.org> Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
* m68k/amiga,atari: Fix specifying multiple debug= parametersGeert Uytterhoeven2013-12-081-1/+4
| | | | | | | | | | | | | | | | | | | | | Since commit d6713b4091a99fa2af2fabdcd2f3fb97f32ecf2e ("m68k: early parameter support"), the user can specify multiple debug consoles using the "debug=" kernel command line parameter. However, as there's only a single struct console object, which is reused, it would actually register the same console object multiple times, causing the following warning: WARNING: CPU: 0 PID: 0 at kernel/printk/printk.c:2233 register_console+0x36/ console 'debug0' already registered Make sure to register the console object only once, to avoid the warning. Note that still only one console (the one corresponding to the last "debug=" parameter) will be active at the same time, as the .write() method of the already registered console object is overwritten by a subsequent "debug=" parameter.

| | | | | | | | | | | | | | | | | Add a dedicated interrupt chip definition for the EtherNAT CPLD interrupts. SMC91C111 and ISP1160 chips have separate interrupts that can be enabled and disabled in a CPLD register at offset 0x23 from the card base. Note the CPLD interrupt control register is mapped on demand, whenever any interrupt enable/disable action is requested. The EtherNAT USB driver still needs interrupts disabled around reset and start actions. In particular, we cannot entirely rely on the irq_startup being called first. The smc91x and isp116x-hcd drivers will use this feature. Signed-off-by: Michael Schmitz <schmitz@debian.org> Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>

* m68k/atari: Reserve some ST-RAM early on for device buffer useMichael Schmitz2011-07-301-285/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on an original patch from Michael Schmitz: Because mem_init() is now called before device init, devices that rely on ST-RAM may find all ST-RAM already allocated to other users by the time device init happens. In particular, a large initrd RAM disk may use up enough of ST-RAM to cause atari_stram_alloc() to resort to __get_dma_pages() allocation. In the current state of Atari memory management, all of RAM is marked DMA capable, so __get_dma_pages() may well return RAM that is not in actual fact DMA capable. Using this for frame buffer or SCSI DMA buffer causes subtle failure. The ST-RAM allocator has been changed to allocate memory from a pool of reserved ST-RAM of configurable size, set aside on ST-RAM init (i.e. before mem_init()). As long as this pool is not exhausted, allocation of real ST-RAM can be guaranteed. Other changes: - Replace the custom allocator in the ST-RAM pool by the existing allocator in the resource subsystem, - Remove mem_init_done and its hook, as memory init is now done before device init, - Remove /proc/stram, as ST-RAM usage now shows up under /proc/iomem, e.g. 005f2000-006f1fff : ST-RAM Pool 005f2000-0063dfff : atafb 0063e000-00641fff : ataflop 00642000-00642fff : SCSI Signed-off-by: Michael Schmitz <schmitz@debian.org> [Andreas Schwab <schwab@linux-m68k.org>: Use memparse()] [Geert: Use the resource subsystem instead of a custom allocator] Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>

* m68k: Define rtc_lock on AtariGeert Uytterhoeven2008-10-141-0/+3
| | | | | | | | | | | | | | | | The nvram and rtc-cmos drivers use the spinlock rtc_lock to protect against concurrent accesses to the CMOS memory. As m68k doesn't support SMP or preempt yet, the spinlock calls tend to get optimized away, but not for all configurations, causing in some rare cases: | ERROR: "rtc_lock" [drivers/rtc/rtc-cmos.ko] undefined! | ERROR: "rtc_lock" [drivers/char/nvram.ko] undefined! Add the spinlock to the Atari core code to avoid this.

| | | | | | | | | | | | This patch changes m68k to use the new bcd2bin/bin2bcd functions instead of the obsolete BCD_TO_BIN/BIN_TO_BCD/BCD2BIN/BIN2BCD macros. It also remove local bcd2bin/bin2bcd implementations in favor of the global ones.
