Disable jumbo frames for 82573L alltogether and when ASPM is enabled since the hardware has problems with it. For the NICs that do support this in the 82573 series we set ERT_2048 to attempt to receive as much traffic as early as we can. Signed-off-by:

With a patch, ethtool can now signify the driver to advertise more than just a single speed/duplex setting. This allows you to tell the card to advertise in 10/100 in any speed if you don't have a gigabit switch for instance. Signed-off-by:

Unify our shutdown/suspend/resume code and make it similar to e1000: e1000_shutdown now calls suspend which does the exact same thing on shutdown except saving PCI config state on suspend. WoL setup code is now also more simple and works even when CONFIG_PM is not set, which was previously broken. Signed-off-by: -

Convert cmm's usage of kernel_thread to kthread_run. Also create the cmmthread at module load time, so it is possible to check if creation of the thread fails. In addition the cmmthread now gets terminated when the module gets unloaded instead of leaving a stale kernel thread. Also check the return values of other registration functions at module load and handle their return values appropriately. Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Signed-off-by:

Include the host architecture's ptrace-abi.h instead of ptrace.h. There was some cpp mangling of names around the ptrace.h include to avoid symbol clashes between UML and the host architecture. Most of these can go away. The exception is struct pt_regs, which is convenient to have in userspace, but must be renamed in order that UML can define its own. ptrace-x86_64.h needed to have some now-obsolete cpp cruft and a declaration removed.

The use of SEGMENT_RPL_MASK in the i386 ptrace.h introduced by x86-allow-a-kernel-to-not-be-in-ring-0.patch broke the UML build, as UML includes the underlying architecture's ptrace.h, but has no easy access to the x86 segment definitions. Rather than kludging around this, as in the past, this patch splits the userspace-usable parts, which are the bits that UML needs, of ptrace.h into ptrace-abi.h, which is included back into ptrace.h. Thus, there is no net effect on i386. As a side-effect, this creates a ptrace header which is close to being usable in /usr/include. x86_64 is also treated in this way for consistency. There was some trailing whitespace there, which is cleaned up. Signed-off-by:

The KSTK_* macros used an inordinate amount of stack. In order to overcome an impedance mismatch between their interface, which just returns a single register value, and the interface of get_thread_regs, which took a full pt_regs, the implementation created an on-stack pt_regs, filled it in, and returned one field. do_task_stat calls KSTK_* twice, resulting in two local pt_regs, blowing out the stack. This patch changes the interface (and name) of get_thread_regs to just return a single register from a jmp_buf. The include of archsetjmp.h" in registers.h to get the definition of jmp_buf exposed a bogus include of <setjmp.h> in start_up.c. <setjmp.h> shouldn't be used anywhere any more since UML uses the klibc setjmp/longjmp.

set_interval returns an error instead of panicing if setitimer fails. Some of its callers now check the return. enable_timer is largely tt-mode-specific, so it is marked as such, and the only skas-mode caller is made to call set-interval instead. user_time_init was a no-value-added wrapper around set_interval, so it is gone. Since set_interval is now called from kernel code, callers no longer pass ITIMER_* to it. Instead, they pass a flag which is converted into ITIMER_REAL or ITIMER_VIRTUAL. Signed-off-by:

Have most signals go through an arch-provided handler which recovers the sigcontext and then calls a generic handler. This replaces the ARCH_GET_SIGCONTEXT macro, which was somewhat fragile. On x86_64, recovering %rdx (which holds the sigcontext pointer) must be the first thing that happens. sig_handler duly invokes that first, but there is no guarantee that I can see that instructions won't be reordered such that %rdx is used before that. Having the arch provide the handler seems much more robust. Some signals in some parts of UML require their own handlers - these places don't call set_handler any more. They call sigaction or signal themselves. Signed-off-by:

- Various cleanups in the sigio code. - Removed explicit zero-initializations of a few structures. - Improved some error messages. - An API change - there was an asymmetry between reactivate_fd calling maybe_sigio_broken, which goes through all the machinery of figuring out if a file descriptor supports SIGIO and applying the workaround to it if not, and deactivate_fd, which just turns off the descriptor. This is changed so that only activate_fd calls maybe_sigio_broken, when the descriptor is first seen. reactivate_fd now calls add_sigio_fd, which is symmetric with ignore_sigio_fd. This removes a recursion which makes a critical section look more critical than it really was, obsoleting a big comment to that effect. This requires keeping track of all descriptors which are getting the SIGIO treatment, not just the ones being polled at any given moment, so that reactivate_fd, through add_sigio_fd, doesn't try to tell the SIGIO thread about descriptors it doesn't care about.

This patch adds an implementation of setjmp and longjmp to UML, allowing access to the inside of a jmpbuf without needing the access macros formerly provided by libc. The implementation is stolen from klibc. I copy the relevant files into arch/um. I have another patch which avoids the copying, but requires klibc be in the tree. setjmp and longjmp users required some tweaking. Includes of <setjmp.h> were removed and includes of the UML longjmp.h were added where necessary. There are also replacements of siglongjmp with UML_LONGJMP which I somehow missed earlier.

Make swsusp use memory bitmaps to store its internal information during the resume phase of the suspend-resume cycle. If the pfns of saveable pages are saved during the suspend phase instead of the kernel virtual addresses of these pages, we can use them during the resume phase directly to set the corresponding bits in a memory bitmap. Then, this bitmap is used to mark the page frames corresponding to the pages that were saveable before the suspend (aka "unsafe" page frames). Next, we allocate as many page frames as needed to store the entire suspend image and make sure that there will be some extra free "safe" page frames for the list of PBEs constructed later. Subsequently, the image is loaded and, if possible, the data loaded from it are written into their "original" page frames (ie. the ones they had occupied before the suspend). The image data that cannot be written into their "original" page frames are loaded into "safe" page frames and their "original" kernel virtual addresses, as well as the addresses of the "safe" pages containing their copies, are stored in a list of PBEs. Finally, the list of PBEs is used to copy the remaining image data into their "original" page frames (this is done atomically, by the architecture-dependent parts of swsusp). Signed-off-by:

Introduce the memory bitmap data structure and make swsusp use in the suspend phase. The current swsusp's internal data structure is not very efficient from the memory usage point of view, so it seems reasonable to replace it with a data structure that will require less memory, such as a pair of bitmaps. The idea is to use bitmaps that may be allocated as sets of individual pages, so that we can avoid making allocations of order greater than 0. For this reason the memory bitmap structure consists of several linked lists of objects that contain pointers to memory pages with the actual bitmap data. Still, for a typical system all of these lists fit in a single page, so it's reasonable to introduce an additional mechanism allowing us to allocate all of them efficiently without sacrificing the generality of the design. This is done with the help of the chain_allocator structure and associated functions. We need to use two memory bitmaps during the suspend phase of the suspend-resume cycle. One of them is necessary for marking the saveable pages, and the second is used to mark the pages in which to store the copies of them (aka image pages). First, the bitmaps are created and we allocate as many image pages as needed (the corresponding bits in the second bitmap are set as soon as the pages are allocated). Second, the bits corresponding to the saveable pages are set in the first bitmap and the saveable pages are copied to the image pages. Finally, the first bitmap is used to save the kernel virtual addresses of the saveable pages and the second one is used to save the contents of the image pages. Signed-off-by:
