bsp/csb336: Memory map update and jump to start at image start provided. CSB336 i.MX1/i.MXS memory map organization - SDRAM starts at address 0x08000000 but 2 MB are reserved for boot-block/loader (or other use) before RTEMS image origin/load address (that is kept from previous setup) - Caching of 30 MB of SDRAM used for RTEMS (start at 0x08200000) is changed to writeback mode which provides higher throughput. - The first 1 MB of RTEMS dedicated SDRAM is remapped to address 0 to provide area for ARM CPU exceptions table. - Internal registers and rest of the Flash (above 1 MB) are mapped one to one. Registers region is extended to 2 MB to cover eSRAM found on i.MX1 chip variant. - The first two megabytes of SDRAM unused by RTEMS are mapped with attributes to allow specific purposes. - the first MB (at address 0x08000000) is nocached to allow directly set some values read by booot-block after warm reset - the second MB (at address 0x08100000) is set for write-through caching. That allows to use memory for LCD frame-buffer without need to flush cache after each redraw. Jump to start provided at address 0x08200000 allows to load application image even as plain binary file and start it by jump to image start address. Signed-off-by: Pavel Pisa <ppisa@…>

bsp/csb336: Fix MMU _ttbl_base location to not overlap with exception vectors. The initial region (64 bytes) of SDRAM RTEMS image is remapped to provide overlay of the initial/ROM exceptions table. This area cannot be used for MMU mapping table. Different correctly aligned block has to be used for MMU table. Remapping of SDRAM (address 0x08200000) to address 0 is supported only on 1 MB block granularity and that is why SDRAM_VEC area has to be 1 MB aligned too but unused part of remapped region can be freely used for other purposes (as MMU tables).

12:54 PM Changeset in rtems [d19cce29]4.11 by Sebastian Huber <sebastian.huber@…>
score: Per-CPU thread dispatch disable level Use a per-CPU thread dispatch disable level. So instead of one global thread dispatch disable level we have now one instance per processor. This is a major performance improvement for SMP. On non-SMP configurations this may simplifiy the interrupt entry/exit code. The giant lock is still present, but it is now decoupled from the thread dispatching in _Thread_Dispatch(), _Thread_Handler(), _Thread_Restart_self() and the interrupt entry/exit. Access to the giant lock is now available via _Giant_Acquire() and _Giant_Release(). The giant lock is still implicitly acquired via _Thread_Dispatch_decrement_disable_level(). The giant lock is only acquired for high-level operations in interrupt handlers (e.g. release of a semaphore, sending of an event). As a side-effect this change fixes the lost thread dispatch necessary indication bug in _Thread_Dispatch(). A per-CPU thread dispatch disable level greatly simplifies the SMP support for the interrupt entry/exit code since no spin locks have to be acquired in this area. It is only necessary to get the current processor index and use this to calculate the address of the own per-CPU control. This reduces the interrupt latency considerably. All elements for the interrupt entry/exit code are now part of the Per_CPU_Control structure: thread dispatch disable level, ISR nest level and thread dispatch necessary. Nothing else is required (except CPU port specific stuff like on SPARC).

score: Add and use _Per_CPU_Acquire_all(). Add and use _Per_CPU_Release_all(). The context switch user extensions are invoked in _Thread_Dispatch(). This change is necessary to avoid the giant lock in _Thread_Dispatch().

11:30 AM Changeset in rtems [9bf7467]4.11 by Sebastian Huber <sebastian.huber@…>
score: Use an ISR lock for TOD Two issues are addressed. 1. On single processor configurations the set/get of the now/uptime timestamps is now consistently protected by ISR disable/enable sequences. Previously nested interrupts could observe partially written values since 64-bit writes are not atomic on 32-bit architectures in general. This could lead to non-monotonic uptime timestamps. 2. The TOD now/uptime maintanence is now independent of the giant lock. This is the first step to remove the giant lock in _Thread_Dispatch().

10:59 AM Changeset in rtems [2d915cf]4.11 by Sebastian Huber <sebastian.huber@…>
score: Add and use ISR locks ISR locks are low-level locks to protect critical sections accessed by threads and interrupt service routines. On single processor configurations the ISR locks degrade to simple ISR disable/enable sequences. No additional storage or objects are required. This synchronization primitive is supported on SMP configurations. Here SMP locks are used.

2:26 PM Changeset in rtems [21ff802]4.11 by Sebastian Huber <sebastian.huber@…>
smp: Delete _ISR_Disable_on_this_core(), etc. Delete _ISR_Enable_on_this_core(), _ISR_Flash_on_this_core(), _ISR_SMP_Disable(), _ISR_SMP_Enable(), _ISR_SMP_Flash(). The ISR disable/enable interface has no parameter to pass a specific object. Thus it is only possible to implement a single global lock object with this interface. Using the ISR disable/enable as the giant lock on SMP configurations is not feasible. Potentially blocking resource obtain sequences protected by the thread dispatch disable level are subdivided into smaller ISR disabled critical sections. This works since on single processor configurations there is only one thread of execution that can block. On SMP this is different (image a mutex obtained concurrently by different threads on different processors). The thread dispatch disable level is currently used as the giant lock. There is not need to complicate things with this unused interface.

smp: Delete _ISR_SMP_Initialize()
1:46 PM Changeset in rtems [10b51ae]4.11 by Sebastian Huber <sebastian.huber@…>
score: Critical section change in _Thread_Dispatch If we enter _Thread_Dispatch() then _Thread_Dispatch_disable_level must be zero. Single processor RTEMS assumes that stores of non-zero values to _Thread_Dispatch_disable_level are observed by interrupts as non-zero values. Move the _Thread_Dispatch_set_disable_level( 1 ) out of the first ISR disabled critical section. In case interrupts happen between the _Thread_Dispatch_set_disable_level( 1 ) and _ISR_Disable( level ) then the interrupt will observe a non-zero _Thread_Dispatch_disable_level and will not issue a _Thread_Dispatch() and we can enter the ISR disabled section directly after interrupt processing. This change leads to symmetry between the single processor and SMP configuration.
