2010-07-20SYSLINK: ipc - adapt gatehwspinlock module to use hwspinlock driverSuman Anna
The gatemp, gatehwspinlock & gatepeterson modules have been enhanced to support reserved resources for each gate_type. This change is done as part of the gatehwspinlock adaptation to the open-source hwspinlock driver code. gatemp module was managing all the spinlocks previously, and with this patch, gatemp module will only control and manage a contiguous block of spinlocks from 4 to 31. The h/w spinlocks 0 to 3 will be reserved for usage by I2C driver. All the spinlocks except the reserved spinlocks are acquired upfront in the gatehwspinlock_setup function, instead of requesting it during create time. This ensures the GateMP module has control over these so that BIOS-side functionality can remain the same as before. Signed-off-by: Suman Anna <s-anna@ti.com>

Patch to add suport to build hwspinlock modules Signed-off-by: Simon Que <sque@ti.com>
2010-07-20omap:hwspinlock-added hwspinlock driverSimon Que
Created driver for OMAP hardware spinlock. This driver supports: - Reserved spinlocks for internal use - Dynamic allocation of unreserved locks - Lock, unlock, and trylock functions, with or without disabling irqs/preempt - Registered as a platform device driver The device initialization uses hwmod to configure the devices. One device will be created for each IP. It will pass spinlock register offset info to the driver. The device initialization file is: arch/arm/mach-omap2/hwspinlocks.c The driver takes in register offset info passed in device initialization. It uses hwmod to obtain the base address of the hardware spinlock module. Then it reads info from the registers. The function hwspinlock_probe() initializes the array of spinlock structures, each containing a spinlock register address calculated from the base address and lock offsets. The device driver file is: arch/arm/plat-omap/hwspinlock.c Here's an API summary: int hwspinlock_lock(struct hwspinlock *); Attempt to lock a hardware spinlock. If it is busy, the function will keep trying until it succeeds. This is a blocking function. int hwspinlock_trylock(struct hwspinlock *); Attempt to lock a hardware spinlock. If it is busy, the function will return BUSY. If it succeeds in locking, the function will return ACQUIRED. This is a non-blocking function. int hwspinlock_unlock(struct hwspinlock *); Unlock a hardware spinlock. struct hwspinlock *hwspinlock_request(void); Provides for "dynamic allocation" of a hardware spinlock. It returns the handle to the next available (unallocated) spinlock. If no more locks are available, it returns NULL. struct hwspinlock *hwspinlock_request_specific(unsigned int); Provides for "static allocation" of a specific hardware spinlock. This allows the system to use a specific spinlock, identified by an ID. If the ID is invalid or if the desired lock is already allocated, this will return NULL. Otherwise it returns a spinlock handle. int hwspinlock_free(struct hwspinlock *); Frees an allocated hardware spinlock (either reserved or unreserved).

2010-07-20ARM: flush_ptrace_access: invalidate all I-cachesWill Deacon
copy_to_user_page can be used by access_process_vm to write to an executable page of a process using a mapping acquired by kmap. For systems with I-cache aliasing, flushing the I-cache using the Kernel mapping may leave stale data in the I-cache if the user mapping is of a different colour. This patch replaces the coherent_kern_range call in flush_ptrace_access with a D-cache flush followed by a system-wide I-cache invalidation. This is required on all systems where the size of a way in the I-cache is larger than PAGE_SIZE.

2010-07-20ARM: errata: TLBIASIDIS and TLBIMVAIS operations can broadcast a faulty ASIDWill Deacon
On versions of the Cortex-A9 prior to r2p0, performing TLB invalidations by ASID match can result in the incorrect ASID being broadcast to other CPUs. As a consequence of this, the targetted TLB entries are not invalidated across the system. This workaround changes the TLB flushing routines to invalidate entries regardless of the ASID.
