From e81b3295bc54eb0d03f4cdfc8cbf72e731d1b402 Mon Sep 17 00:00:00 2001 From: Nathan Fontenot Date: Tue, 2 Oct 2012 16:55:01 +0000 Subject: powerpc+of: Add /proc device tree updating to of node add/remove When adding or removing a device tree node we should also update the device tree in /proc/device-tree. This action is already done in the generic OF code for adding/removing properties of a node. This patch adds this functionality for nodes.

This makes this functionality available to all architectures. Additionally the notification chain is updated to allow notifications for property add/remove/update. To make this work a pointer to a new struct (of_prop_reconfig) is passed to the routines in the notification chain. The of_prop_reconfig property contains a pointer to the node containing the property and a pointer to the property itself. In the case of property updates, the property pointer refers to the new property.

At least with a modern compiler it's inlined, so there's no point in it being static, we could #define it but it's only used in one place. By reworking the logic we can drop count and just decrement the max value as a loop counter. Also switch to a while loop so we actually print no more than 64 frames as you'd expect based on the variable name.

There is thus no need for initialize_flash_pde_data to call remove_flash_pde on the same argument. remove_flash_pde kfrees the data field of its argument, and does not clear that field, so this amounts ot a possible double free.

While they are targeted primarily towards BookE users, user-space applications such as GDB have started using them for BookS too. This patch enables the use of generic hardware breakpoint interfaces for these new flags. Apart from the usual benefits of using generic hw-breakpoint interfaces, these changes allow debuggers (such as GDB) to use a common set of ptrace flags for their watchpoint needs and allow more precise breakpoint specification (length of the variable can be specified).

It is the responsibility of the caller to set it again. However, when the caller sets the hardware breakpoint again using ptrace(PTRACE_SET_DEBUGREG, child_pid, 0, addr), the hardware breakpoint is not enabled. While gdb's approach is to unregister and re-register the hardware breakpoint every time the breakpoint is hit - which is working fine, this could affect other programs trying to re-register hardware breakpoint without unregistering. This patch enables hardware breakpoint if the caller is re-registering.

A new set of exception vectors is added at 0xc000_0000_0000_4xxx. When the HW takes us here, MSR IR/DR will be set already and we no longer need a costly RFID to turn the MMU back on again. The original 0x0 based exception vectors remain for when the HW can't leave the MMU on. Examples of this are when we can't trust the current the MMU mappings, like when we are changing from guest to hypervisor (HV 0 -> 1) or when the MMU was off already. In these cases the HW will take us to the original 0x0 based exception vectors with the MMU off as before. The below macros are copies of the macros used at the 0x0 offset but modified to handle the MMU being on. In these macros we use the link register to jump to the secondary handlers rather than using RFID (RFID was also use to turn on the MMU).

A new set of exception vectors is added at 0xc000_0000_0000_4xxx. When the HW takes us here, MSR IR/DR will be set already and we no longer need a costly RFID to turn the MMU back on again. The original 0x0 based exception vectors remain for when the HW can't leave the MMU on. Examples of this are when we can't trust the current MMU mappings, like when we are changing from guest to hypervisor (HV 0 -> 1) or when the MMU was off already. In these cases the HW will take us to the original 0x0 based exception vectors with the MMU off as before. This uses the new macros added previously too implement these new execption vectors at 0xc000_0000_0000_4xxx. We exit these exception vectors using mflr/blr (rather than mtspr SSR0/RFID), since we don't need the costly MMU switch anymore. This moves the __end_interrupts marker down past these new 0x4000 vectors since they will need to be copied down to 0x0 when the kernel is not at 0x0.

The following patch removes the locking from update_vsyscall_tz(). Locking is not only unnecessary because the vdso code copies the data unprotected in __kernel_gettimeofday() but also erroneous because updating the tb_update_count is not atomic and introduces a hard to reproduce race condition between update_vsyscall() and update_vsyscall_tz(), which further causes user space process to loop forever in vdso code. The below scenario describes the race condition, x==0 Boot CPU other CPU proc_P: x==0 timer interrupt update_vsyscall x==1 x++;sync settimeofday update_vsyscall_tz x==2 x++;sync x==3 sync;x++ sync;x++ proc_P: x==3 (loops until x becomes even) Because the ++ operator would be implemented as three instructions and not atomic on powerpc.

CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.
