* Change the startup code to fix a memory leak and to allow us toMarcel Moolenaar2002-12-105-41/+141
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | accept load options (=command line options). The call graph changes from *entry*->efi_main->efi_init, where efi_main is the EFI equivalent of main to *entry*->efi_main->main, where main is what you'd expect. efi_main now is what efi_init was. The prototype of main follows that of C. The first argument is argc and the second is argv. There is no third argument. Allocation of heap pages is now handled by the EFI library and it now deallocates the pages when main() returns or when exit() is called. This allows us to safely return to the boot manager (or EFI shell) without leaks. EFI applications are responsible to free all memory themselves. Handling of the load options is a bit tricky. There are either no load options, load options in ASCII or load options in Unicode. The EFI library will translate the ASCII options to Unicode options as to simplify user code. Since the load options are passed as a single string (if present) and main() accepts argc and argv, the startup code also has to split the string into words and build the argv vector. Here the trickiness starts. When the loader is started from the EFI shell, argv[0] will automaticly load the program name. In all other cases (ie through the boot manager), this is not the case. Unfortunately, there's no trivial way to check. Hence, a set of conditions is checked to determine if we need to fill in argv[0] ourselves or not. This checking is not perfect. There are known cases where it fails to do the right thing. The logic works for most expected cases, though. This includes the case where no options are given.

* The boot manager sets the watchdog timer to 5 minutes before invokingMarcel Moolenaar2002-12-082-12/+20
| | | | | | | | | | | | | | | | | | | | | | a boot option. When the timer expires the machine is rebooted. Disable the watchdog timer for 2 reasons: o We're an interactive program. We cannot guarantee that we've booted the kernel in the time available to us. There have been situations where netbooting the right kernel took 2 tries and more time than given. Not to speak of the normal behaviour to have the loader sitting at the prompt while the user is off doing other things (such as figuring out what to type next ;-) o We may not boot a kernel at all. We may exit as the result of the user typing quit (assuming it took less than 5 minutes to type it :-). It is documented that loaders should have disabled the watchdog timer if they return to the boot manager. Not doing so would cause a reboot while in the boot manager. This appears to be harmless, besides of course the actual reboot. Approved by: re (weisse karte) Notes: svn path=/head/; revision=107683
* In efi_cons_poll we check if a key is present (pending) by checkingMarcel Moolenaar2002-12-081-4/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | the signaled state of the apropriate event. As a side-effect of checking the event, it's signaled state is cleared if it was set. In efi_cons_getchar we used to wait for the apropriate event to be signaled before reading a character. This however does not work if we poll before reading the characteri, such as during autoboot. On a more compliant EFI implementation this resulted in the behaviour that hitting a key during autoboot would stop the countdown, but would then wait for a new character to arrive instead of reading the already pending key that stopped the countdown. The correct behaviour for efi_cons_getchar is to try to read a key and if none is pending, to wait for the apropriate event to signal the arrival of a new key. Note that with the previous behaviour, the second key would determine how the autoboot was interrupted. This would indicate that the first key got lost. This indicates that EFI does not necessarily maintain a queue of pending keys. FWIW... Approved by: re (carte blanche) French corrected by: various people :-) Notes: svn path=/head/; revision=107682

* Remove a left-over virtual mapping of uncached I/O port space.Marcel Moolenaar2002-11-284-34/+6
| | | | | | | | | | | | | | | | Previous kernels unwantingly depended on this mapping, but as of version 1.123 of src/sys/ia64/ia64/machdep.c this dependency has been removed. Consequently, one has to update the kernel before updating the loader. The documented/recommended upgrade will suffice in this case. Due to a visible (from the kernels point of view) change in behaviour, bump the loader version number from 0.3 to 1.0. Approved by: re (carte blanc) Notes: svn path=/head/; revision=107367

* Create a new 32-bit fs_flags word in the superblock. Add code to moveKirk McKusick2002-11-271-1/+1
| | | | | | | | | | | | | | | | | | | | the old 8-bit fs_old_flags to the new location the first time that the filesystem is mounted by a new kernel. One of the unused flags in fs_old_flags is used to indicate that the flags have been moved. Leave the fs_old_flags word intact so that it will work properly if used on an old kernel. Change the fs_sblockloc superblock location field to be in units of bytes instead of in units of filesystem fragments. The old units did not work properly when the fragment size exceeeded the superblock size (8192). Update old fs_sblockloc values at the same time that the flags are moved.
