The system manager provides an event notification mechanism for reporting events like thermal alert and button presses. It also provides support to control system shutdown and startup.

During power outages, the UPS notifies the system for a shutdown. In the current setup, it isn't possible to poweron when power is restored. This patch fixes the issue by calling the right ibm,power-off-ups token during such events. It also adds a sysfs interface so userspace can specify whether or not to power on when power is restored.

-- cgit v1.2.3-70-g09d2 From 28ee086d5b36aab2931f6740e409bb0fb6c65e5f Mon Sep 17 00:00:00 2001 From: Richard Purdie Date: Thu, 8 Feb 2007 22:25:09 +0000 Subject: backlight: Fix external uses of backlight internal semaphore backlight_device->sem has a very specific use as documented in the header file. The external users of this are using it for a different reason, to serialise access to the update_status() method. backlight users were supposed to implement their own internal serialisation of update_status() if needed but everyone is doing things differently and incorrectly. Therefore add a global mutex to take care of serialisation for everyone, once and for all. Locking for get_brightness remains optional since most users don't need it. Also update the lcd class in a similar way.

This patch splits the two types of data and allows simplifcation of some code.

This is not generally correct. It will be incorrect, for example, if a hardware platform uses a single port but not the first port. Here, we add an explicit port_number field to struct mv643xx_eth_platform_data. This makes the mv643xx_eth_platform_data structure required, but that isn't an issue since all users currently provide it already.

This patch also adds comments for usage of cfg_addr and cfg_data in pci_controller structure. We use them in irregular way, and the original code is short of explanations about them.

In addition, it saves and restores the SLB content on context switches which makes it harder to properly handle those invalidations. This patch removes the saving & restoring for now, something more efficient might be found later on. It also adds a spu_flush_all_slbs(mm) that can be used by the core mm code to flush the SLBs of all SPEs that are running a given mm at the time of the flush. In order to do that, it adds a spinlock to the list of all SPEs and move some bits & pieces from spufs to spu_base.c Signed-off-by: Benjamin Herrenschmidt --- arch/powerpc/mm/hash_utils_64.c | 6 +++ arch/powerpc/mm/hugetlbpage.c | 4 ++ arch/powerpc/platforms/cell/spu_base.c | 81 +++++++++++++++++++++++++----- arch/powerpc/platforms/cell/spufs/sched.c | 13 +---- arch/powerpc/platforms/cell/spufs/switch.c | 62 ++--------------------- include/asm-powerpc/spu.h | 7 +++ include/asm-powerpc/spu_csa.h | 4 -- 7 files changed, 91 insertions(+), 86 deletions(-) (limited to 'arch/powerpc/platforms') diff --git a/arch/powerpc/mm/hash_utils_64.c b/arch/powerpc/mm/hash_utils_64.c index c0d2a694fa3..3c7fe2c65b5 100644 --- a/arch/powerpc/mm/hash_utils_64.c +++ b/arch/powerpc/mm/hash_utils_64.c @@ -685,6 +685,9 @@ int hash_page(unsigned long ea, unsigned long access, unsigned long trap) "non-cacheable mapping\n"); psize = mmu_vmalloc_psize = MMU_PAGE_4K; } +#ifdef CONFIG_SPE_BASE + spu_flush_all_slbs(mm); +#endif } if (user_region) { if (psize != get_paca()->context.user_psize) { @@ -759,6 +762,9 @@ void hash_preload(struct mm_struct *mm, unsigned long ea, mmu_psize_defs[MMU_PAGE_4K].sllp; get_paca()->context = mm->context; slb_flush_and_rebolt(); +#ifdef CONFIG_SPE_BASE + spu_flush_all_slbs(mm); +#endif } } if (mm->context.user_psize == MMU_PAGE_64K) diff --git a/arch/powerpc/mm/hugetlbpage.c b/arch/powerpc/mm/hugetlbpage.c index 8c77c791f87..f6ffaaa7a5b 100644 --- a/arch/powerpc/mm/hugetlbpage.c +++ b/arch/powerpc/mm/hugetlbpage.c @@ -24,6 +24,7 @@ #include #include #include +#include #include @@ -513,6 +514,9 @@ int prepare_hugepage_range(unsigned long addr, unsigned long len, pgoff_t pgoff) if ((addr + len) > 0x100000000UL) err = open_high_hpage_areas(current->mm, HTLB_AREA_MASK(addr, len)); +#ifdef CONFIG_SPE_BASE + spu_flush_all_slbs(current->mm); +#endif if (err) { printk(KERN_DEBUG "prepare_hugepage_range(%lx, %lx)" " failed (lowmask: 0x%04hx, highmask: 0x%04hx)\n", diff --git a/arch/powerpc/platforms/cell/spu_base.c b/arch/powerpc/platforms/cell/spu_base.c index c43999a10de..eba7a2641dc 100644 --- a/arch/powerpc/platforms/cell/spu_base.c +++ b/arch/powerpc/platforms/cell/spu_base.c @@ -38,8 +38,61 @@ const struct spu_management_ops *spu_management_ops; const struct spu_priv1_ops *spu_priv1_ops; +static struct list_head spu_list[MAX_NUMNODES]; +static LIST_HEAD(spu_full_list); +static DEFINE_MUTEX(spu_mutex); +static spinlock_t spu_list_lock = SPIN_LOCK_UNLOCKED; + EXPORT_SYMBOL_GPL(spu_priv1_ops); +void spu_invalidate_slbs(struct spu *spu) +{ + struct spu_priv2 __iomem *priv2 = spu->priv2; + + if (spu_mfc_sr1_get(spu) & MFC_STATE1_RELOCATE_MASK) + out_be64(&priv2->slb_invalidate_all_W, 0UL); +} +EXPORT_SYMBOL_GPL(spu_invalidate_slbs); + +/* This is called by the MM core when a segment size is changed, to + * request a flush of all the SPEs using a given mm + */ +void spu_flush_all_slbs(struct mm_struct *mm) +{ + struct spu *spu; + unsigned long flags; + + spin_lock_irqsave(&spu_list_lock, flags); + list_for_each_entry(spu, &spu_full_list, full_list) { + if (spu->mm == mm) + spu_invalidate_slbs(spu); + } + spin_unlock_irqrestore(&spu_list_lock, flags); +} + +/* The hack below stinks... try to do something better one of + * these days...

Instead, introduce arch/powerpc/sysdev/timer.c which creates a sys device and handles time of day suspend/resume through that. This should probably be replaced by using the generic RTC framework but for now it gets rid of the arcane powermac specific hack.

Previously, you'd need to manually select UCC_FAST if you want any "fast" UCC devices, such as Gigabit Ethernet. Now, the QE Gigabit Ethernet option is always available if the device has a QE, and UCC_FAST is automatically enabled. A side-effect is that the "QE Options" menu no longer exists.

Instead of doing an spu_release before entering spu_setup_isolated and then calling the complicated spu_acquire_exclusive we can now simply enter the function locked an in guaranteed runnable state, so that the only bit of spu_acquire_exclusive that's left is the call to spu_unmap_mappings. Similarly there's no more need to unlock and reacquire the state_mutex when spu_setup_isolated is done, but we can always return with the lock held and only drop it in spu_run_init in the failure case.

This has multiple bad side-effects: - it becomes impossible to suspend the context during page faults - if an spu program attempts to access its own mmio areas through DMA, we get an immediate livelock when the nopage function tries to acquire the same mutex This patch makes the page fault logic operate on a struct spu_context instead of a struct spu, and moves it from spu_base.c to a new file fault.c inside of spufs. We now also need to copy the dar and dsisr contents of the last fault into the saved context to have it accessible in case we schedule out the context before activating the page fault handler.

Therefore, this patch re-arranges the 4xx Kconfig code to allow this. In addition we: - use "select" instead of depends to configure the correct config options for specific 4xx CPUs and workarounds, which makes the information about specific boards and CPUs less scattered. -
