2015-02-10First step towards making uiomove() take a size_t size argument:Miod Vallat
- rename uiomove() to uiomovei() and update all its users. - introduce uiomove(), which is similar to uiomovei() but with a size_t. - rewrite uiomovei() as an uiomove() wrapper. ok kettenis@

2014-07-12reboot(9): Shutdown system by signaling init(8) from kernel where appropriateMasao Uebayashi
Some ports watch temperature in MD and try to shutdown system, when overheated, by calling directly (re)boot(9). Change this to signal init(8) from kernel, as acpi(4) and acpitz(4) do, which has been more tested. This also helps to clarify design that ``clean shutdown must be always started by init(8)''. Note that SIGUSR2 causes init(8) to call reboot(2) with RB_POWERDOWN, as acpi(4) etc. already does. It is reasonable, pointed out by kettenis@, considering system is overheated and immediate reboot may be dangerous. OK deraadt@ miod@

after discussions with beck deraadt kettenis.
2014-07-12boot(9), reboot(9): Migrate MD callers of boot(9) to reboot(9)Masao Uebayashi
I have found that some ports call boot(9) from machine-dependent code to reboot system. These should be changed to either: - Sending signal to init(8) to trigger it to shutdown system cleanly, like acpi(4) does, in cases where found problems don't prevent system from working immediately, or - Just doing panic(9) if the situation is severely broken. For now, just rewrite boot() to reboot(). Actual fixes follow. Discussed with & OK from kettenis@

2014-01-19Initialize ci_randseed better using arc4random() + a trick. Remove theTheo de Raadt
libkern srandom() API since it is not suitable for this use. ok kettenis miod
2013-11-261 << 31 cleanup. Eitan Adler pointed out that there has been aTheo de Raadt
resurrection of the bad idiom in the tree. sufficient review by miod, kettenis, tedu
2012-02-25Fix a bad case of htole64() being used instead of htole32() when setting upMiod Vallat
pci configuration space accesses to allow proper recovery from failure, causing the measure not to have any effect and the system to freeze hard. Fixes use of pcidump -x on B1000, and probably more systems.
2011-09-19%b format strings take the value before the bitname string, not the otherMiod Vallat
way around.

in the kernel, not only when com @ gsc is there. ok miod@
2011-05-01Fix counting of interrupts for devices that attach to elroy(4). SharedMark Kettenis
interrupts would be counted double, once for the interrupting device and once for the device at the head of the chain. The handlers would run properly though. Avoid this by giving each device its own interrupt counter instead of using the counter provided by the generic interrupt handling code for the head of the chain.
2011-04-23Stop calling shared interrupt handlers as soon as one of them return 1Mark Kettenis
(positive interrupt was for me), like we do on other architectures. This is done here, at the elroy(4) driver level, since this is where shared PCI interrupts are handled. We could do something similar for dino(4) but this optimization is probably not very relevant there. ok deraadt@

2010-12-26Kill pmap_phys_address(), and force every driver's mmap() routine to returnMiod Vallat
a physical address [more precisely, something suitable to pass to pmap_enter()'sphysical address argument]. This allows MI drivers to implement mmap() routines without having to know about the pmap_phys_address() implementation and #ifdef obfuscation.
2010-12-04Introduce a new pci routine, pci_conf_size(), which returns the size of aMiod Vallat
given pcitag_t configuration address space. Currently, all pci controllers will return the usual 0x100 bytes of PCI configuration space, but this will eventually change on PCIe-capable controlers. ok kettenis@

2010-06-28Allow tty drivers to request larger buffers at attach time using aTheo de Raadt
max-baud-rate hint. Adjust TTYHOG (the nearly full logic) to this new situation. The larger buffers are required by the very high speed KDDI devices in Japan (CF com, or USB ucom) so those are the only two drivers which currently ask for a larger buffer size. ok yasuoka miod
