| | | | | | | | | | | | | | | | | | | PT_DETACH ptrace(2) requests from functioning as advertised in the manual page. As described in kern/35175, the PT_DETACH request will, under certain circumstances, pass an unwanted signal on to the traced process upan detaching from it. The PT_CONTINUE request will sometimes fail if you make it pass a signal that has "properties" that differ from the properties of the signal that origionally caused the traced process to be stopped. Since PT_KILL is nothing than PT_CONTINUE with SIGKILL, it is broken too. In the PT_KILL case, this leads to an unkillable process.

When flow control is enabled, if the operating system doesn't acknowledge the packet buffer filling, the card will begin to generate ethernet quench packets, but appears to get into a feedback loop of some sort, hosing local switches. This is a temporary workaround for 5.1: the ability to configure flow control should probably be exposed by some or another management interface on ethernet link layer devices.

There is no need to inherit any flags from the forking process; the old method however can cause flags set in userland for the forking process to be bogusly set in kernel mode when the newly forked process runs for the first time (in particular PSL_T, which is set for userland when the process is single-stepped; this would cause trace traps in kernel mode).

| | | | | | | | | | | | | | | | | | | | - Fix compilation without GEM_DEBUG. - Do not #define GEM_DEBUG by default; it adds overhead (due to bzero()ing RX space) and is not needed any more, since the driver is quite stable now. - Fix watchdog timeouts when failing to load TX packets. - Do not forcibly limit the number of descriptors used for a packet to GEM_NTXSEGS, by passing this number to bus_dma_tag_create(). There is no requirement for a limit any lower than the total number of available descriptors, and the present limit caused network problems due to mbuf chains requiring more descriptors.

* This file creates register sets based on the runtime specification.Marcel Moolenaar2003-05-151-0/+180
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The advantage of using register sets is that you don't focus on each register seperately, but instead instroduce a level of abstraction. This reduces the chance of errors, and also simplifies the code. The register sers form the basis of everything register. The sets in this file are: struct _special contains all of the control related registers, such as instruction pointer and stack pointer. It also contains interrupt specific registers like the faulting address. The set is roughly split in 3 groups. The first contains the registers that define a context or thread. This is the only group that the kernel needs to switch threads. The second group contains registers needed in addition to the first group needed to switch userland threads. This group contains the thread pointer and the FP control register. The third group contains those registers we need for execption handling and are used on top of the first two groups. struct _callee_saved, struct _callee_saved_fp These sets contain the preserved registers, including the NaT after spilling. The general registers (including branch registers) are seperated from the FP registers for ptrace(2). struct _caller_saved, struct _caller_saved_fp These sets contain the scratch registers based on SDM 2.1, This means that both ar.csd and ar.ccd are included here, even though they contain ia32 segment register descriptions. We keep seperate NaT bits for scratch and preserved registers, because they are never saved/restored at the same time. struct _high_fp The upper 96 FP registers that can be enabled/disabled seperately on the CPU from the lower 32 FP registers. Due to the size of this set, we treat them specially, even though they are defined as scratch registers.

| | | | | | | | | | | | | | | | | | | | save and restore "sets" of registers in various places. The restorectx and swapctx functions are used by cpu_switch() and deal with the special registers, as well as the preserved registers. The *callee_saved* functions are used to save and restore the preserved registers (integer and floating-point). They are useful for signal delivery and ptrace support. The save_high_fp and restore_high_fp functions are used to "load" and "unload" to and from the CPU as part of lazy context switching. The ia32 specific context functions have been kept with the ia32 code. Approved by: re@ (blanket) Notes: svn path=/head/; revision=115018

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | on the epc instruction. The epc instruction, given the permissions of the page in which the epc is located, allows the privilege level to be increased with little or no overhead. The previous privilege level is recorded in the current frame marker and is restored by a regular (function) return. Since the epc instruction has to live in a page with non-standard properties, we hardwire a "gateway" page in the address space. The address of the gateway page is exported to userland in ar.k7. This allows us to rewire the page without breaking the ABI. The syscall stubs in libc are regular function calls that slightly differ from the normal runtime. The difference is mostly to simplify the stubs themselves by by moving some of the logic to the kernel. The libc stubs call into the gateway page (offset 0), from where the kernel trampolines to the code that sets up a minimal trapframe and arranges to execute from the kernel stack. The way back is basicly the same. The kernel returns to the gateway page, whereby privilege is dropped, and jumps back to the syscall stub. Only the special registers are saved in the trapframe. None of the scratch registers are preserved and since the kernel follows the same runtime model, none of the preserved registers are saved. Future enhancements can include the implementation of lightweight syscalls, where kernel functions are performed without setting up a trapframe. Good candidates are the *context syscalls for example. Now that there's a gateway page from which code can be executed in a non-privileged context, we also have the ideal place to put the signal trampolines. By moving the signal trampolines from the user stack to the gateway page, we open up the doors to unexecutable stacks. The gateway page contains signal trampolines for both the "legacy" break-based syscall code and the new and improved epc- based syscall code.

| | | | | | | | | | | | | | | | | | | | | available by Hewlett-Packard under the MIT license. The unwinder is small, clean and fast and needed little adaptation for use in the kernel. This import has embedded in it the changes needed to make it build in a kernel environment. To optimize the common case, the kernel will minimize the number of registers saved by not saving the preserved registers. In case access to preserved registers is needed (signal handling, ptrace) the kernel will unwind to the context of the syscall or exception. For this we need an unwinder.
