v1.2.3-70-g09d2 From 28c7a19d230228ab9ae61c300c5003a2400fadd3 Mon Sep 17 00:00:00 2001 From: Narayanan G Date: Tue, 22 Nov 2011 13:56:55 +0530 Subject: dmaengine/ste_dma40: Add support to use lcla area from esram This patch provides an option of having the lcla (link address) in ESRAM instead of allocating it. The bool value (use_esram_lcla) in the stedma40_platform_data if set to true, then the lcla address would be taken from platform resources. Also, the corresponding esram regulator is managed in the suspend/resume functions.

It can arbitrarily map between pixel formats and internal representation and also between internal representation and the physical connection to the display. The driver used to change the mapping between internal representation and display connection depending on the user selected bpp which is wrong. Instead, the mapping is specified by the hardware, so an additional field in platform data is added to describe the connection between i.MX and the display. The default for this field is RGB666 which seems to be the only configuration which works without this patch, so I assumed that all in Kernel boards are connected this way. This patch has been tested on a RGB666 connected display and a RGB888 connected display in both 16bpp and 32bpp modes.

The implementation was based off the structure of the MIPS platform and information in this (http://lists.fedoraproject.org/pipermail/arm/2009-October/000382.html) mailing list thread. The required audit_syscall_exit and audit_syscall_entry checks were added to ptrace using the standard registers for system call values (r0 through r3). A thread information flag was added for auditing (TIF_SYSCALL_AUDIT) and a meta-flag was added (_TIF_SYSCALL_WORK) to simplify modifications to the syscall entry/exit. Now, if either the TRACE flag is set or the AUDIT flag is set, the syscall_trace function will be executed. The prober changes were made to Kconfig to allow CONFIG_AUDITSYSCALL to be enabled. Due to platform availability limitations, this patch was only tested on the Android platform running the modified "android-goldfish-2.6.29" kernel. A test compile was performed using Code Sourcery's cross-compilation toolset and the current linux-3.0 stable kernel. The changes compile without error. I'm hoping, due to the simple modifications, the patch is "obviously correct".

This reverts commit 5dd7bf59e0e8563265b3e5b33276099ef628fcc7. Conflicts: scripts/mod/file2alias.c This change is wrong on many levels. First and foremost, it causes a regression. On boot on Assabet, which this patch gives a codec id of 'ucb1x00', it gives: ucb1x00 ID not found: 1005 0x1005 is a valid ID for the UCB1300 device. Secondly, this patch is way over the top in terms of complexity. The only device which has been seen to be connected with this MCP code is the UCB1x00 (UCB1200, UCB1300 etc) devices, and they all use the same driver. Adding a match table, requiring the codec string to match the hardware ID read out of the ID register, etc is completely over the top when we can just read the hardware ID register. --- arch/arm/mach-sa1100/assabet.c | 1 - arch/arm/mach-sa1100/cerf.c | 1 - arch/arm/mach-sa1100/collie.c | 8 +----- arch/arm/mach-sa1100/include/mach/mcp.h | 2 -- arch/arm/mach-sa1100/lart.c | 1 - arch/arm/mach-sa1100/shannon.c | 1 - arch/arm/mach-sa1100/simpad.c | 8 +----- drivers/mfd/mcp-core.c | 44 ++---------------------------- drivers/mfd/mcp-sa11x0.c | 7 ++--- drivers/mfd/ucb1x00-core.c | 48 ++++++++------------------------- drivers/mfd/ucb1x00-ts.c | 2 +- include/linux/mfd/mcp.h | 7 ++--- include/linux/mfd/ucb1x00.h | 5 +--- include/linux/mod_devicetable.h | 11 -------- scripts/mod/file2alias.c | 10 ------- 15 files changed, 21 insertions(+), 135 deletions(-) (limited to 'arch/arm') diff --git a/arch/arm/mach-sa1100/assabet.c b/arch/arm/mach-sa1100/assabet.c index d8aa1c28353..0c4b76ab4d8 100644 --- a/arch/arm/mach-sa1100/assabet.c +++ b/arch/arm/mach-sa1100/assabet.c @@ -202,7 +202,6 @@ static struct irda_platform_data assabet_irda_data = { static struct mcp_plat_data assabet_mcp_data = { .mccr0 = MCCR0_ADM, .sclk_rate = 11981000, - .codec = "ucb1x00", };

This was not the case for v6, where HARVARD_CACHE was defined to indicate the L1 cache topology. This patch removes the erroneous compile-time check for HARVARD_CACHE in proc-v7.S, ensuring that we perform I-side invalidation at boot.

In some cases, the kernel will take an interrupt too early, depending on what junk was present in the registers at reset time. The fix is to set the Timer Control Register to 0 before registering the clock_event_device and enabling the interrupt. Problem seen on VE (Cortex A5) and Tegra.

This is caused by the way the mappings are described on this platform (define replaced by hex values for clarity): { /* GIC CPU interface mapping */ .virtual = IO_ADDRESS(0x1F000100), .pfn = __phys_to_pfn(0x1F000100), .length = SZ_4K, .type = MT_DEVICE, }, { /* GIC distributor mapping */ .virtual = IO_ADDRESS(0x1F001000), .pfn = __phys_to_pfn(0x1F001000), .length = SZ_4K, .type = MT_DEVICE, } The first mapping ends up reserving two pages, and clashes with the second one, which triggers a BUG_ON in vm_area_add_early(). In order to solve this problem, treat the MPCore private memory region (containing the SCU, the GIC and the TWD) as a single region, as described in the TRM: http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0360f/CACGDJJC.html The EB11MP is converted the same way, even if it manages to avoid the problem.

This is because while the addresses in the mcount records do not have the zero bit set, the IP reported by the mcount call does have it set (because it is copied from the LR). This mismatch causes the ops filtering in ftrace_ops_list_func() to not call the relevant tracers. Fix this by clearing the zero bit before adjusting the LR for the mcount instruction size.

However, OMAP3 has sysconfig bits that OMAP2 doesn't have, so we need to split those structs into OMAP2 and OMAP3 specific versions. This patch only splits the structs, without changing the contents. This is a prerequisite for a subsequent fix.

Currently this is broken as dss_core is listed in chip/revision specific hwmod lists while other DSS hwmods are listed in common list which is registered first. This patch moves DSS hwmods (except for dss_core) to the separate list which is registered last to ensure that dss_core is already registered. This solves the problem with BUG() in L3 interrupt handler on boards with DSS enabled in bootloader. The long-term fix to this is to ensure modules are set up in dependency order in the hwmod core code.

This patch solves the problem by adding hot-plug-detection into the HDMI IP driver. This is not a real HPD support in the sense that nobody else than the IP driver gets to know about the HPD events, but is only meant to fix the HW bug. The strategy is simple: If the display device is turned off by the user, the PHY power is set to OFF. When the display device is turned on by the user, the PHY power is set either to LDOON or TXON, depending on whether the HDMI cable is connected. The reason to avoid PHY OFF when the display device is on, but the cable is disconnected, is that when the PHY is turned OFF, the HDMI IP is not "ticking" and thus the DISPC does not receive pixel clock from the HDMI IP. This would, for example, prevent any VSYNCs from happening, and would thus affect the users of omapdss. By using LDOON when the cable is disconnected we'll avoid the HW bug, but keep the HDMI working as usual from the user's point of view.

Currently this function is also called by code handling MMC3, and if .internal_clock is set in platform data (by default it currently is), it will set MMCSDIO2ADPCLKISEL for MMC2 instead of MMC3 (MMC3 doesn't have such bit so nothing actually needs to be done). This breaks 2nd SD slot on pandora. Fix this by changing hsmmc23_before_set_reg() to only handle MMC2.

Clearly that's totally bogus. Moreover, the original premise of the 'fix' patch was wrong: | The condition checking boundaries of the requested and existing | mappings didn't take in-page offset into consideration though, | which lead to obscure and hard to debug problems when requested | mapping crossed end of the static one. as the code immediately above this loop does: size = PAGE_ALIGN(offset + size); so 'size' already contains the requested offset into the page.

This involves copying from the user stack into the current thread's vfp_hard_struct and then flushing the new data out to the hardware registers. This is problematic when using a preemptible kernel because we could be context switched whilst updating the vfp_hard_struct. If the current thread has made use of VFP since the last context switch, the VFP notifier will copy from the hardware registers into the vfp_hard_struct, overwriting any data that had been partially copied by the signal code. Disabling preemption across copy_from_user calls is a terrible idea, so instead we move the VFP thread flush *before* we update the vfp_hard_struct. Since the flushing is performed lazily, this has the effect of disabling VFP and clearing the CPU's VFP state pointer, therefore preventing the thread from being updated with stale data on the next context switch.

This leads to a race condition which can cause the thread vfp state to become corrupted if lazy VFP context save occurs due to preemption in between the time thread->vfpstate is read and the time the modified state is written back. This may occur if preemption occurs during the execution of a ptrace() call which modifies the VFP register state of a thread. Such instances should be very rare in most realistic scenarios -- none has been reported, so far as I am aware. Only uniprocessor systems should be affected, since VFP context save is not currently lazy in SMP kernels. The problem was introduced by my earlier patch migrating to use regsets to implement ptrace. This patch does a vfp_sync_hwstate() before reading thread->vfpstate, to make sure that the thread's VFP state is not live in the hardware registers while the registers are modified. Thanks to Will Deacon for spotting this.

To determine the cache attributes (line size, number of sets, etc.) the assembly first writes the CSSELR register to select a cache level and then reads the CCSIDR register. The CSSELR register is banked per-cpu and is used to determine which cache level CCSIDR reads. If the task is migrated between when the CSSELR is written and the CCSIDR is read the CCSIDR value may be for an unexpected cache level (for example L1 instead of L2) and incorrect cache flushing could occur. Disable interrupts across the write and read so that the correct cache attributes are read and used for the cache flushing routine. We disable interrupts instead of disabling preemption because the critical section is only 3 instructions and we want to call v7_dcache_flush_all from __v7_setup which doesn't have a full kernel stack with a struct thread_info. This fixes a problem we see in scm_call() when flush_cache_all() is called from preemptible context and sometimes the L2 cache is not properly flushed out.

This works around an oversight in the OMAP UART hardware present in OMAP34xx and earlier: an idle UART won't send a wakeup when the TX FIFO threshold is reached. This causes long delays during data transmission when the MPU powerdomain enters a low-power mode. The MPU interrupt controller is not able to respond to interrupts when it's in a low-power state, so the TX buffer is not refilled until another wakeup event occurs. This fix changes the erratum i291 DMA idle workaround. Rather than toggling between force-idle and no-idle, it will toggle between smart-idle and no-idle. The important part of the workaround is the no-idle part, so this shouldn't result in any change in behavior. This fix should work on all OMAP UARTs. Future patches intended for the 3.4 merge window will make this workaround conditional on a "feature" flag, and will use the OMAP36xx+ TX event wakeup support. Thanks to Kevin Hilman for mentioning the erratum i291 workaround, which led to the development of this approach.

These platforms have pins configured as GPIO when the selector is not 0x0. However the common code assumes the selector is always 0x0 for a GPIO lines. It then ignores the GPIO bits in the MPP definitions, resulting in that Orion5x machines cannot correctly configure there GPIO lines. The Fix removes the assumption that the selector is always 0x0. In order that none GPIO configurations are correctly blocked, Kirkwood and mv78xx0 MPP definitions are corrected to only set the GPIO bits for GPIO configurations. This third version, which does not contain any whitespace changes, and is rebased on v3.3-rc2.

The patch "ARM: orion: Consolidate USB platform setup code.", commit 4fcd3f374a928081d391cd9a570afe3b2c692fdc broke USB on TS-7800 and other orion5x boards, because the wrong type of PHY was being passed to the EHCI driver in the platform data. Orion5x needs EHCI_PHY_ORION and all the others want EHCI_PHY_NA. Allow the mach- code to tell the generic plat-orion code which USB PHY enum to place into the platform data. Version 2: Rebase to v3.3-rc2.

In this case, it fails because we try to register some data for the wl12xx driver, but as the driver is not configured, a stub function is used which simply returns -ENOSYS. Let's do the simple thing for -rc and print the error code. Also, the return code from platform_register_device() at each of these sites was not being checked. Add some checking, and again print the error code. This should be fixed properly for the next merge window so we don't issue error messages merely because a driver is not configured.

This is because v7_setup (which is called very early during boot) calls v7_flush_dcache_all, and the save_and_disable_irqs added by that patch ends up attempting to call into lockdep C code (trace_hardirqs_off()) when we are in no position to execute it (no stack, MMU off). Fix this by using a notrace variant of save_and_disable_irqs. The code already uses the notrace variant of restore_irqs.

Below is the dump for reference : Unable to handle kernel paging request at virtual address 007e900 pgd = cdc20000 [007e9000] *pgd=00000000 Internal error: Oops: 5 [#1] SMP Modules linked in: CPU: 0 Not tainted (3.3.0-rc3-pm+debug+initramfs #9) PC is at twd_update_frequency+0x34/0x48 LR is at twd_update_frequency+0x10/0x48 pc : [] lr : [] psr: 60000093 sp : ce311dd8 ip : 00000000 fp : 00000000 r10: 00000000 r9 : 00000001 r8 : ce310000 r7 : c0440458 r6 : c00137f8 r5 : 00000000 r4 : c0947a74 r3 : 00000000 r2 : 007e9000 r1 : 00000000 r0 : 00000000 Flags: nZCv IRQs off FIQs on Mode SVC_32 ISA ARM Segment usr Control: 10c5387d Table: 8dc20019 DAC: 00000015 Process sh (pid: 599, stack limit = 0xce3102f8) Stack: (0xce311dd8 to 0xce312000) 1dc0: 6000c 1de0: 00000001 00000002 00000000 00000000 00000000 00000000 00000 1e00: ffffffff c093d8f0 00000000 ce311ebc 00000001 00000001 ce310 1e20: c001386c c0437c4c c0e95b60 c0e95ba8 00000001 c0e95bf8 ffff4 1e40: 00000000 00000000 c005ef74 ce310000 c0435cf0 ce311ebc 00000 1e60: ce352b40 0007a120 c08d5108 c08ba040 c08ba040 c005f030 00000 1e80: c08bc554 c032fe2c 0007a120 c08d4b64 ce352b40 c08d8618 ffff8 1ea0: c08ba040 c033364c ce311ecc c0433b50 00000002 ffffffea c0330 1ec0: 0007a120 0007a120 22222201 00000000 22222222 00000000 ce357 1ee0: ce3d6000 cdc2aed8 ce352ba0 c0470164 00000002 c032f47c 00034 1f00: c0331cac ce352b40 00000007 c032f6d0 ce352bbc 0003d090 c0930 1f20: c093d8bc c03306a4 00000007 ce311f80 00000007 cdc2aec0 ce358 1f40: ce8d20c0 00000007 b6fe5000 ce311f80 00000007 ce310000 0000c 1f60: c000de74 ce987400 ce8d20c0 b6fe5000 00000000 00000000 0000c 1f80: 00000000 00000000 001fbac8 00000000 00000007 001fbac8 00004 1fa0: c000df04 c000dd60 00000007 001fbac8 00000001 b6fe5000 00000 1fc0: 00000007 001fbac8 00000007 00000004 b6fe5000 00000000 00202 1fe0: 00000000 beb565f8 00101ffc 00008e8c 60000010 00000001 00000 [] (twd_update_frequency+0x34/0x48) from [] ) [] (smp_call_function_single+0x17c/0x1c8) from [] (twd_cpufreq_transition+0x24/0x30) from [) [] (notifier_call_chain+0x44/0x84) from [] () [] (__srcu_notifier_call_chain+0x70/0xa4) from [] (srcu_notifier_call_chain+0x18/0x20) from [] (cpufreq_notify_transition+0xc8/0x1b0) from [] (omap_target+0x1b4/0x28c) from [] (__cpuf) [] (__cpufreq_driver_target+0x50/0x64) from [] (cpufreq_set+0x78/0x98) from [] (store_sc) [] (store_scaling_setspeed+0x5c/0x74) from [) [] (store+0x58/0x74) from [] (sysfs_write_fi) [] (sysfs_write_file+0x80/0xb4) from [] (vfs) [] (vfs_write+0xa8/0x138) from [] (sys_write) [] (sys_write+0x40/0x6c) from [] (ret_fast_s) Code: e594300c e792210c e1a01000 e5840004 (e7930002) ---[ end trace 5da3b5167c1ecdda ]--- Reported-by: Kevin Hilman Acked-by: Marc Zyngier Tested-by: Kevin Hilman Signed-off-by: Santosh Shilimkar Signed-off-by: Russell King --- arch/arm/kernel/smp_twd.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'arch/arm') diff --git a/arch/arm/kernel/smp_twd.c b/arch/arm/kernel/smp_twd.c index 4285daa077b..7a79b24597b 100644 --- a/arch/arm/kernel/smp_twd.c +++ b/arch/arm/kernel/smp_twd.c @@ -129,7 +129,7 @@ static struct notifier_block twd_cpufreq_nb = { static int twd_cpufreq_init(void) { - if (!IS_ERR(twd_clk)) + if (twd_evt && *__this_cpu_ptr(twd_evt) && !IS_ERR(twd_clk)) return cpufreq_register_notifier(&twd_cpufreq_nb, CPUFREQ_TRANSITION_NOTIFIER); -- cgit v1.2.3-70-g09d2 From e23e8c0690d2952dce53e712d01d5b2179f98b64 Mon Sep 17 00:00:00 2001 From: Myron Stowe Date: Tue, 7 Feb 2012 15:26:44 -0700 Subject: ARM/PCI: Remove ARM's duplicate definition of 'pcibios_max_latency' The patch series to re-factor PCI's 'latency timer' setup (re: http://marc.info/?l=linux-kernel&m=131983853831049&w=2) forgot to remove the ARM specific definition of 'pcibios_max_latency' once such had been moved into the pci core resulting in ARM related compile errors - drivers/built-in.o:(.data+0x230): multiple definition of `pcibios_max_latency' arch/arm/common/built-in.o:(.data+0x40c): first defined here make[1]: *** [vmlinux.o] Error 1 In the series, patch 2/16 (commit 168c8619fd8) converted the ARM specific version of 'pcibios_set_master()' to a non-inlined version.
