From 894673ee6122a3ce1958e1fe096901ba5356a96b Mon Sep 17 00:00:00 2001 From: Jon Smirl Date: Mon, 10 Jul 2006 04:44:13 -0700 Subject: [PATCH] tty: Remove include of screen_info.h from tty.h screen_info.h doesn't have anything to do with the tty layer and shouldn't be included by tty.h. This patches removes the include and modifies all users to directly include screen_info.h. struct screen_info is mainly used to communicate with the console drivers in drivers/video/console. Note that this patch touches every arch and I have no way of testing it. If there is a mistake the worst thing that will happen is a compile error.

I removed the passing of the trigger to the map() calls entirely, it was not a good idea to have one call do two different things. It also fixes a couple of corner cases. Mapping a linux virtual irq to a physical irq now does only that. Setting the trigger is a different action which has a different call. The main changes are: - I no longer call host->ops->map() for an already mapped irq, I just return the virtual number that was already mapped. It was called before to give an opportunity to change the trigger, but that was causing issues as that could happen while the interrupt was in use by a device, and because of the trigger change, map would potentially muck around with things in a racy way. That was causing much burden on a given's controller implementation of map() to get it right. This is much simpler now. map() is only called on the initial mapping of an irq, meaning that you know that this irq is _not_ being used. You can initialize the hardware if you want (though you don't have to). - Controllers that can handle different type of triggers (level/edge/etc...) now implement the standard irq_chip->set_type() call as defined by the generic code. That means that you can use the standard set_irq_type() to configure an irq line manually if you wish or (though I don't like that interface), pass explicit trigger flags to request_irq() as defined by the generic kernel interfaces. Also, using those interfaces guarantees that your controller set_type callback is called with the descriptor lock held, thus providing locking against activity on the same interrupt (including mask/unmask/etc...) automatically. A result is that, for example, MPIC's own map() implementation calls irq_set_type(NONE) to configure the hardware to the default triggers. - To allow the above, the irq_map array entry for the new mapped interrupt is now set before map() callback is called for the controller. - The irq_create_of_mapping() (also used by irq_of_parse_and_map()) function for mapping interrupts from the device-tree now also call the separate set_irq_type(), and only does so if there is a change in the trigger type. - While I was at it, I changed pci_read_irq_line() (which is the helper I would expect most archs to use in their pcibios_fixup() to get the PCI interrupt routing from the device tree) to also handle a fallback when the DT mapping fails consisting of reading the PCI_INTERRUPT_PIN to know wether the device has an interrupt at all, and the the PCI_INTERRUPT_LINE to get an interrupt number from the device. That number is then mapped using the default controller, and the trigger is set to level low. That default behaviour works for several platforms that don't have a proper interrupt tree like Pegasos. If it doesn't work for your platform, then either provide a proper interrupt tree from the firmware so that fallback isn't needed, or don't call pci_read_irq_line() - Add back a bit that got dropped by my main rework patch for properly clearing pending IPIs on pSeries when using a kexec Signed-off-by: Benjamin Herrenschmidt Cc: Paul Mackerras Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- arch/powerpc/kernel/ibmebus.c | 2 +- arch/powerpc/kernel/irq.c | 47 ++++---- arch/powerpc/kernel/pci_32.c | 36 +++++-- arch/powerpc/kernel/pci_64.c | 36 +++++-- arch/powerpc/platforms/cell/interrupt.c | 4 +- arch/powerpc/platforms/cell/spider-pic.c | 70 ++++++------ arch/powerpc/platforms/cell/spu_base.c | 6 +- arch/powerpc/platforms/iseries/irq.c | 4 +- arch/powerpc/platforms/powermac/pci.c | 13 +-- arch/powerpc/platforms/powermac/pic.c | 8 +- arch/powerpc/platforms/pseries/ras.c | 3 +- arch/powerpc/platforms/pseries/xics.c | 34 +++--- arch/powerpc/sysdev/i8259.c | 4 +- arch/powerpc/sysdev/mpic.c | 180 ++++++++++++++----------------- drivers/char/hvsi.c | 2 +- drivers/macintosh/macio_asic.c | 2 +- include/asm-powerpc/irq.h | 38 +++---- 17 files changed, 258 insertions(+), 231 deletions(-) (limited to 'arch/powerpc') diff --git a/arch/powerpc/kernel/ibmebus.c b/arch/powerpc/kernel/ibmebus.c index 97ddc02a3d42..68e5ab0443d2 100644 --- a/arch/powerpc/kernel/ibmebus.c +++ b/arch/powerpc/kernel/ibmebus.c @@ -323,7 +323,7 @@ int ibmebus_request_irq(struct ibmebus_dev *dev, unsigned long irq_flags, const char * devname, void *dev_id) { - unsigned int irq = irq_create_mapping(NULL, ist, 0);

It's important that it fails when things aren't correct in order to trigger fallback mecanisms that are necessary to make some machines work properly.

Rozanski F. ). - Add exports for functions that might be called from modules - Fix Kconfig depdencies on PMAC_BACKLIGHT. - Fix locking issues on calls from inside the driver (reported by Aristeu S. Rozanski F., too) - Fix wrong calculation of backlight values in some of the drivers - Replace pmac_backlight_key_up/down by inline functions [akpm@osdl.org: fix function prototypes] Signed-off-by: Michael Hanselmann Acked-by: Aristeu S.

-- cgit v1.2.3 From d1a8df9136ff55e554e11ce65854c282965be8f5 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Mon, 3 Jul 2006 14:28:14 +0200 Subject: [POWERPC] fix up front-LED Kconfig This patch fixes the front-LED Kconfig issues I introduced while creating it. Apparently having a dependency isn't enough to have the select not evaluated or something like that. The patch also changes the default configuration for pmac32 select the default for the LED to be the IDE trigger. While I was at it, I completely updated the defconfig and also added snd-aoa to it.

This fixes it by always using a u64 which is what is returned by the OF parsing routines. It also makes translation failure harmless for ISA serial ports. If they can't translate, we can't use the UART early, but we can still let the 8250 driver use it later on by using IO port accessors.

It was pointed out to me by Andi Kleen that if an oops has occured in interrupt context, then calling sleep() in the oops path will only cause a panic, and that it would be really better for it not to be in the path at all. This patch removes the ssleep() call and reworks the console message accordinly. I have a slght concern that the resulting console message is too long, feedback welcome. For powerpc it also unifies the 32bit and 64bit behaviour. Fror x86_64, this patch only updates the console message, as ssleep() is already not present.

The new section ".gnu.hash" replaces ".hash", and allows for more efficient runtime symbol lookups by the dynamic linker. The new ld option --hash-style={sysv|gnu|both} controls whether to produce the old ".hash", the new ".gnu.hash", or both. In some new systems such as Fedora Core 6, gcc by default passes --hash-style=gnu to the linker, so that a standard invocation of "gcc -shared" results in producing a DSO with only ".gnu.hash". The new ".gnu.hash" sections need to be dealt with the same way as ".hash" sections in all respects; only the dynamic linker cares about their contents. To work with older dynamic linkers (i.e. preexisting releases of glibc), a binary must have the old ".hash" section. The --hash-style=both option produces binaries that a new dynamic linker can use more efficiently, but an old dynamic linker can still handle. The new section runs afoul of the custom linker scripts used to build vDSO images for the kernel. On ia64, the failure mode for this is a boot-time panic because the vDSO's PT_IA_64_UNWIND segment winds up ill-formed. This patch addresses the problem in two ways. First, it mentions ".gnu.hash" in all the linker scripts alongside ".hash". This produces correct vDSO images with --hash-style=sysv (or old tools), with --hash-style=gnu, or with --hash-style=both. Second, it passes the --hash-style=sysv option when building the vDSO images, so that ".gnu.hash" is not actually produced. This is the most conservative choice for compatibility with any old userland. There is some concern that some ancient glibc builds (though not any known old production system) might choke on --hash-style=both binaries. The optimizations provided by the new style of hash section do not really matter for a DSO with a tiny number of symbols, as the vDSO has. If someone wants to use =gnu or =both for their vDSO builds and worry less about that compatibility, just change the option and the linker script changes will make any choice work fine.

Introduced a worker to prevent it from directly calling the backlight code. - via-pmu allows the backlight to be grabbed, in which case we need to prevent other kernel code from changing the brightness. - Don't send PMU requests in via-pmu-backlight when the machine is about to sleep or waking up. - More Kconfig fixes.

However, Paul Mackerras suggested that this was somewhat confusing, leadind people to believe that it was panic_on_oops that was the root cause of the fatal exception. On his suggestion, this patch changes the message to simply "Fatal exception". A suitable oops message should already have been displayed.

If xmon is enabled, the CPU(s) enter into the xmon debugger. Unfortunately, the secondary CPU(s) will return to the hung state when they exit from the debugger (returned from die() -> system_reset_exception()). This causes a problem in kdump since the hung CPU(s) will not respond to the IPI sent from kdump. This patch fixes the issue by calling crash_kexec_secondary() directly from system_reset_exception() without returning to the previous state. These secondary CPUs wait 5ms until the kdump boot is started by the primary CPU. In the case we exited from the debugger to "recover" (command 'x' in xmon) the primary and the secondary CPUs will all return from die() -> system_reset_exception() ->crash_kexec_secondary() wait 5ms, then return to the previous state. A kdump boot is not started in this case.

This second processor could have fetched the stream of text from the out-of-line single-stepping area *before* the probe registration completed, possibly due to an earlier (and a different) kprobe hit and hence would see stale data at the slot. Executing such an arbitrary instruction lead to a problem as reported in LTC bugzilla 23555. The correct solution is to call flush_icache_range() as soon as the instruction is copied for out-of-line single-stepping, so the correct instruction is seen on all processors. Thanks to Will Schmidt who tracked this down.

The first is that there is a race between do_gettimeofday and the timer interrupt: 1. do_gettimeofday does get_tb() 2. decrementer exception on boot cpu which runs timer_recalc_offset, which also samples the timebase and updates the do_gtod structure with a greater timebase value. 3. do_gettimeofday calls __do_gettimeofday, which leads to the negative result from tb_val - temp_varp->tb_orig_stamp. The second is caused by taking the boot cpu offline, which can cause the value of tb_last_jiffy to be increased past the currently available timebase, causing the same underflow as above.

Alright, this one is only triggered when slab debugging is enabled. The slabs are assumed to be aligned on a HUGEPTE_TABLE_SIZE boundary. The free path makes use of this assumption and uses the lowest nibble to pass around an index into an array of kmem_cache pointers. With slab debugging turned on, the slab is still aligned, but the "working" object pointer is not. This would break the assumption above that a full nibble is available for the PGF_CACHENUM_MASK. The following patch reduces PGF_CACHENUM_MASK to cover only the two least significant bits, which is enough to cover the current number of 4 pgtable cache types. Then use this constant to mask out the appropriate part of the huge pte pointer.

For the IPIC, IRQ sense values in the device tree equal those in include/linux/irq.h; that's 8 for low assertion (most internal IRQs on mpc83xx), and 2 for high-to-low change. spinlocks added to [un]mask, ack operations; default handler and type now set in host_map; and redundant condition check eliminated.

As a temporary fix, I put a spinlock in there. However, this can have a significant impact on performances. This patch reworks that to use a smarter technique based on the fact that what we need is in fact a rwlock with extremely rare writers (thus optimized for the read path).

This enables the mpic code to deal with mpic controllers with different register layouts and hardware behaviours. This introduces CONFIG_MPIC_WEIRD. For boards with non standard mpic controllers, select CONFIG_MPIC_WEIRD and add its hardware information in the mpic_infos[] array. TSI108/109 PIC takes the first index of weird hardware information table. :) The table can be extended. The Tsi108/109 PIC looks like standard OpenPIC but, in fact, is different in register mapping and behavior. The patch does not affect the behavior of standard mpic. If CONFIG_MPIC_WEIRD is not defined, the code is essentially identical to the current code. [benh@kernel.crashing.org: This patch is a slightly cleaned up version of Zang Roy's support for the TSI108 MPIC variant. It also fixes up MPC7448_hpc2 to use the new version of the type macros and changes the way MPIC is selected in Kconfig to better match what is done for other system devices. ] Signed-off-by: Roy Zang Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Paul Mackerras --- arch/powerpc/Kconfig | 20 +- arch/powerpc/platforms/embedded6xx/Kconfig | 1 + arch/powerpc/platforms/embedded6xx/mpc7448_hpc2.c | 2 +- arch/powerpc/sysdev/mpic.c | 223 ++++++++++++++++------ include/asm-powerpc/mpic.h | 125 ++++++++++++ 5 files changed, 305 insertions(+), 66 deletions(-) (limited to 'arch/powerpc') diff --git a/arch/powerpc/Kconfig b/arch/powerpc/Kconfig index abb325eb8f75..4d4b6fb156e1 100644 --- a/arch/powerpc/Kconfig +++ b/arch/powerpc/Kconfig @@ -354,6 +354,7 @@ endchoice config PPC_PSERIES depends on PPC_MULTIPLATFORM && PPC64 bool "IBM pSeries & new (POWER5-based) iSeries" + select MPIC select PPC_I8259 select PPC_RTAS select RTAS_ERROR_LOGGING @@ -363,6 +364,7 @@ config PPC_PSERIES config PPC_CHRP bool "Common Hardware Reference Platform (CHRP) based machines" depends on PPC_MULTIPLATFORM && PPC32 + select MPIC select PPC_I8259 select PPC_INDIRECT_PCI select PPC_RTAS @@ -373,6 +375,7 @@ config PPC_CHRP config PPC_PMAC bool "Apple PowerMac based machines" depends on PPC_MULTIPLATFORM + select MPIC select PPC_INDIRECT_PCI if PPC32 select PPC_MPC106 if PPC32 default y @@ -380,6 +383,7 @@ config PPC_PMAC config PPC_PMAC64 bool depends on PPC_PMAC && POWER4 + select MPIC select U3_DART select MPIC_BROKEN_U3 select GENERIC_TBSYNC @@ -389,6 +393,7 @@ config PPC_PMAC64 config PPC_PREP bool "PowerPC Reference Platform (PReP) based machines" depends on PPC_MULTIPLATFORM && PPC32 && BROKEN + select MPIC select PPC_I8259 select PPC_INDIRECT_PCI select PPC_UDBG_16550 @@ -397,6 +402,7 @@ config PPC_PREP config PPC_MAPLE depends on PPC_MULTIPLATFORM && PPC64 bool "Maple 970FX Evaluation Board" + select MPIC select U3_DART select MPIC_BROKEN_U3 select GENERIC_TBSYNC @@ -439,12 +445,6 @@ config U3_DART depends on PPC_MULTIPLATFORM && PPC64 default n -config MPIC - depends on PPC_PSERIES || PPC_PMAC || PPC_MAPLE || PPC_CHRP \ - || MPC7448HPC2 - bool - default y - config PPC_RTAS bool default n @@ -812,6 +812,14 @@ config GENERIC_ISA_DMA depends on PPC64 || POWER4 || 6xx && !CPM2 default y +config MPIC + bool + default n + +config MPIC_WEIRD + bool + default n + config PPC_I8259 bool default n diff --git a/arch/powerpc/platforms/embedded6xx/Kconfig b/arch/powerpc/platforms/embedded6xx/Kconfig index ba07a9a7c039..234a861870a8 100644 --- a/arch/powerpc/platforms/embedded6xx/Kconfig +++ b/arch/powerpc/platforms/embedded6xx/Kconfig @@ -80,6 +80,7 @@ config MPC7448HPC2 select DEFAULT_UIMAGE select PPC_UDBG_16550 select MPIC + select MPIC_WEIRD help Select MPC7448HPC2 if configuring for Freescale MPC7448HPC2 (Taiga) platform diff --git a/arch/powerpc/platforms/embedded6xx/mpc7448_hpc2.c b/arch/powerpc/platforms/embedded6xx/mpc7448_hpc2.c index ed00ed2455dd..5d393eb94935 100644 --- a/arch/powerpc/platforms/embedded6xx/mpc7448_hpc2.c +++ b/arch/powerpc/platforms/embedded6xx/mpc7448_hpc2.c @@ -215,7 +215,7 @@ static void __init mpc7448_hpc2_init_IRQ(void) mpic = mpic_alloc(tsi_pic, mpic_paddr, MPIC_PRIMARY | MPIC_BIG_ENDIAN | MPIC_WANTS_RESET | - MPIC_SPV_EOI | MPIC_MOD_ID(MPIC_ID_TSI108), + MPIC_SPV_EOI | MPIC_NO_PTHROU_DIS | MPIC_REGSET_TSI108, 0, /* num_sources used */ 0, /* num_sources used */ "Tsi108_PIC");

The last_jiffy per-cpu variable is only 32 bits on 32-bit machines, but it was being compared with a 64-bit quantity (tb_next_jiffy), which resulted in time not advancing. This fixes it by changing last_jiffy to be 64 bits on all platforms. With this, we no longer need tb_last_stamp as a 32-bit version of tb_last_jiffy, so this gets rid of tb_last_stamp and we just use tb_last_jiffy instead. This also fixes a bug when the boot cpu is not online, because using tb_last_stamp could have caused the wrong timebase origin value to be used when calculating the time of day.

However, both it and the arch/powerpc version have another problem, which is that they use local_irq_disable/enable rather than local_irq_save/restore, and they are called with interrupts disabled. This fixes both problems; it changes a return to a break in the arch/ppc version, and changes both versions to use local_irq_save/restore.

The problem was that I was comparing a 32-bit quantity with a 64-bit quantity, and consequently time wasn't advancing. This makes us use a 64-bit quantity on all platforms, which ends up simplifying the code since we can now get rid of the tb_last_stamp variable (which actually fixes another bug that Ben H and I noticed while going carefully through the code). This works fine on my G4 tibook. Let me know how it goes on your machines.

To preserve ordering between writeX and readX, and to preserve ordering between preceding stores and the readX, the readX family of functions have had an sync added before the load. Although writeX followed by spin_unlock is not officially guaranteed to keep the writeX inside the spin-locked region unless an mmiowb() is used, there are currently drivers that depend on the previous behaviour on powerpc, which was that the mmiowb wasn't actually required. Therefore we have a per-cpu flag that is set by writeX, cleared by __raw_spin_lock and mmiowb, and tested by __raw_spin_unlock. If it is set, __raw_spin_unlock does a sync and clears it. This changes both 32-bit and 64-bit readX/writeX. 32-bit already has a sync in __raw_spin_unlock (since lwsync doesn't exist on 32-bit), and thus doesn't need the per-cpu flag. Tested on G5 (PPC970) and POWER5.

This fixes it by making the CPU read the entry back from memory before using it.
