H. Peter Anvin 61ee294875 [PXEXT] Change the PXE return code for EWOULDBLOCK 
Change the PXE return code for EWOULDBLOCK from PXENV_STATUS_FAILURE
to PXENV_STATUS_TFTP_OPEN.  This code is only used by the FILE_READ
PXEXT call, and is necessary to distinguish "error" from "no data" in
that call.

(The only other nonblocking call is UDP_READ, where the caller doesn't
care about the distinction, however, gPXE doesn't use EWOULDBLOCK
internally to represent this condition in that code.)

H. Peter Anvin d62e89d776 [PXEXT] Add FILE_API_CHECK API function 
Add FILE_API_CHECK to the PXEXT API so the NBP can query the
availability and status of the API.

Michael Brown 92d15eff30 [Settings] Remove assumption that all settings have DHCP tag values 
Allow for settings to be described by something other than a DHCP option
tag if desirable.  Currently used only for the MAC address setting.

Separate out fake DHCP packet creation code from dhcp.c to fakedhcp.c.

Remove notion of settings from dhcppkt.c.

Rationalise dhcp.c to use settings API only for final registration of the
DHCP options, rather than using {store,fetch}_setting throughout.

Michael Brown dbf8a02e8f [libc] Use __builtin_va_list et al in stdarg.h 
The home-grown versions don't work properly for static variadic
functions, when gcc can choose to use a non-standard calling convention.

Michael Brown ee4206a8a7 [DHCP] Fix up fake-packet creation as used by PXENV_GET_CACHED_INFO 
Add dedicated functions create_dhcpdiscover(), create_dhcpack() and
create_proxydhcpack() for use by external code such as the PXE preboot
code.

Register ProxyDHCP options under the global scope "proxydhcp".

Unregister previously-acquired DHCP and ProxyDHCP settings when DHCP
succeeds.

 2008-03-20 23:15:48 +00:00
Michael Brown acfa14423e [Settings] Add per-netdevice settings block 
Add a configuration settings block for each net device.  This will
provide the parent scope for settings applicable only to that network
device (e.g. non-volatile options stored on the NIC, options obtained via
DHCP, etc.).

Expose the MAC address as a setting.
 2008-03-20 21:06:53 +00:00
Michael Brown 260b93bb72 [Settings] Add settings hierarchy 
Add the notion of the settings hierarchy, complete with
register/unregister routines.

Rename set->store and get->fetch to avoid naming conflicts with get/put
as used in reference counting.
 2008-03-20 21:01:32 +00:00
Michael Brown a48b4d9948 [Settings] Start revamping the configuration settings API. 
Add the concept of an abstract configuration setting, comprising a (DHCP)
tag value and an associated byte sequence.

Add the concept of a settings namespace.

Add functions for extracting string, IPv4 address, and signed and
unsigned integer values from configuration settings (analogous to
dhcp_snprintf(), dhcp_ipv4_option(), etc.).

Update functions for parsing and formatting named/typed options to work
with new settings API.

Update NVO commands and config UI to use new settings API.

Michael Brown 070cbebc26 [Timers] Initialise timers on first use 
Timers are sometimes required before the call to initialise(), so we
cannot rely on initialise() to set up the timers before use.

Also fix a potential integer overflow issue in generic_currticks_udelay()
 2008-03-18 15:23:10 +00:00
Michael Brown 2652abdc5f [Timers] Miscellaneous timer system fixes 
Add missing comments to timer code.

Lock system if no suitable timer source is found.

Fix initialisation order so that timers are initialised before code that
needs to use them.
 2008-03-18 14:48:28 +00:00
Michael Brown 5a08b434c7 [Settings] show_setting() functions return snprintf()-style length. 
show_setting() and related functions now return an "actual length" in the
style of snprintf().  This is to allow consumers to allocate buffers large
enough to hold the formatted setting.
 2008-03-18 00:48:23 +00:00
Michael Brown 3e781eb87f Merge branch 'xl0-timer' 2008-03-10 13:02:53 +00:00
Michael Brown b62f2325ba [PXEXT] Add PXENV_FILE_EXEC call to PXE extensions API. 
This allows pxelinux to execute arbitrary gPXE commands.  This is
remarkably unsafe (not least because some of the commands will assume
full ownership of memory and do nasty things like edit the e820 map
underneath the calling pxelinux), but it does allow access to the
"sanboot" command.
 2008-03-04 18:16:30 +00:00
Michael Brown b08a6f5300 [Command] Add "sanboot" command. 2008-03-04 17:59:26 +00:00
Alexey Zaytsev a1572e0ab0 Modify gPXE core and drivers to work with the new timer subsystem 
Signed-off-by: Alexey Zaytsev <alexey.zaytsev@gmail.com>
 2008-03-02 03:41:10 +03:00
Alexey Zaytsev 4006d229e5 Introduce the new timer subsystem. 
Timer subsystem initialization code in core/timer.c

	Split the BIOS and RTDSC timer drivers from i386_timer.c

	Split arch/i386/firmware/pcbios/bios.c into the RTSDC
	timer driver and arch/i386/core/nap.c

	Split the headers properly:
		include/unistd.h - delay functions to be used by the
					gPXE core and drivers.

		include/gpxe/timer.h - the fimer subsystem interface
					to be used by the timer drivers
					and currticks() to be used by
					the code gPXE subsystems.

		include/latch.h	- removed
		include/timer.h - scheduled for removal. Some driver
					are using currticks, which is
					only for core subsystems.

Michael Brown bc3f0a25c6 [Infiniband] Add preliminary support for multi-port devices. 
Arbel and Hermon cards both have multiple ports.  Add the
infrastructure required to register each port as a separate IB
device.  Don't yet register more than one port, since registration
will currently fail unless a valid link is detected.

Use ib_*_{set,get}_{drv,owner}data wrappers to access driver- and
owner-private data on Infiniband structures.
