Michael Brown	9ad5cede96	Set DHCP_MESSAGE_TYPE option within the main options block. This ... doesn't seem to be required by the RFCs, but at least ISC dhcpd and ethereal refuse to recognise it otherwise.	2006-07-20 00:18:50 +00:00
Michael Brown	881b90e82c	Packets without a DHCP_MESSAGE_TYPE option are probably just BOOTP ... packets.	2006-07-20 00:03:25 +00:00
Michael Brown	29b358dd39	conn->local_port is now network-endian; do not swap when comparing ... against value in header. Temporarily disable RX checksumming; it's broken and is holding up work on higher-layer protocols .	2006-07-20 00:03:01 +00:00

Michael Brown	82f3295794	Use more standardised format specifiers in debug messages (e.g. %p for ... a pointer).	2006-07-19 18:45:18 +00:00
Michael Brown	ab633f6a73	Reserve space for lower-layer headers when allocating packet buffer. ... Use pkb_available() rather than pkb_len() (which will always return 0 on a freshly allocated buffer). udp_send() should assume that the buffer has already been allocated.	2006-07-19 18:21:30 +00:00
Michael Brown	6858b14a34	Add pkb_available()	2006-07-19 18:16:48 +00:00

Michael Brown	254fe6e00e	Split DHCP packet creation into two parts: creating the basic packet ... structure, and populating it with options. This should allow us to use the same basic options list for both DHCPDISCOVER and DHCPREQUEST, plus making it much easier to set the non-constant parameters (e.g. requested IP address) in request packets.	2006-07-19 12:12:45 +00:00
Michael Brown	e40ebb67de	Allow for calling find_dhcp_option() with "options" set to NULL, in order ... to search through all registered option blocks. Move some static inlines that are likely to be used frequently into dhcpopts.c as normal functions, to save space.	2006-07-19 11:05:38 +00:00

Michael Brown	35b0233baa	Tidy up hex_dump() output.	2006-07-17 13:04:29 +00:00
Michael Brown	b24947f0c0	Add sketch code to reassemble a DHCP packet from our internal "everything ... is a DHCP option" data structures. We need this code in order to be able to return a DHCP packet to a PXE NBP which reflects options from our multiple sources (e.g. NVS and DHCP server). This is expensive, but necessary. Having paid this cost, we may as well try to use the same code to generate our DHCP request packets, since the process is similar.	2006-07-17 12:47:22 +00:00
Michael Brown	12da7ea475	Add (untested) code for parsing a received DHCP packet and constructing a ... DHCP options block from the contents.	2006-07-15 19:24:55 +00:00

Michael Brown	17eea9f933	Fix bug with >256 cylinders. ... Allow our functions to return a non-zero, non-error status (since the INT 13 Extensions Check has to return the API version in the register that is otherwise always used for the error code). Report a non-zero API version from the INT 13 Extensions Check; GRUB now uses extended reads.	2006-06-08 19:28:08 +00:00

Michael Brown	ef37f78cbe	Cut out almost all the optional code paths, drastically simplifying the ... flow of control through this code. We now always add PCI and PnP headers even for ISA ROMs; there's no harm in doing so. UNDI loader is still missing.	2006-06-06 15:33:39 +00:00

Michael Brown	1f394c2f7c	Backing out last change; no immediate plans to make the whole block-device ... layer asynchronous, so keeping the sync/async boundary within aoedev.c seems cleanest for now.	2006-06-01 11:14:59 +00:00
Michael Brown	d6866202f9	Until we have a functioning UDP stack and PXE API again, there's not much ... point trying to use the old boot sequence. Replaced with a call to the AoE demo code, so that people can at least build and try something useful.	2006-06-01 11:07:31 +00:00
Michael Brown	d21fc3610f	Added sample AoE test code to tree	2006-06-01 11:05:36 +00:00
Michael Brown	f6d20bb0f4	Put in a method to get the MAC address for the AoE target. (It's not ... elegant, but it works).	2006-05-31 19:12:17 +00:00
Michael Brown	99ef98d0bf	ATA devices are now asynchronous. The ATA layer itself now performs the ... async_wait(), though we may wish to move this higher up the stack, and consider making the block device model asynchronous. (There is only a marginal cost for synchronous devices, since they can simply call async_done() before returning; async_wait() will work seamlessly in this situation).	2006-05-31 18:57:11 +00:00
Michael Brown	cf96d325d8	Missing from previous checkin. ... This is the core portion of the async I/O interface.	2006-05-31 18:45:43 +00:00
Michael Brown	68125bc441	Added generic asynchronous operations code. ... Removed data_in_len and data_out_len from ata_command structure; the lengths are implied by the sector count and the presence of the data_in or data_out pointers. Changed AoE code to use subcommands by default, and made aoe_issue() nonblocking (with completion via async_wait()).	2006-05-31 14:34:17 +00:00
Michael Brown	73a449e96b	Added drivers/ata directory (forgot to check this in previously).	2006-05-31 14:31:48 +00:00

Michael Brown	1db1a6dad3	Added first sketch of a generic retry timer mechanism. The idea is to use ... these timer objects in AoE and UDP protocols (where there is no underlying retransmission mechanism) without requiring each protocol to implement its own individual retry logic. Eventually, we should be able to use the same timer code for TCP retransmissions as well.	2006-05-29 14:55:07 +00:00

Michael Brown	9f86754f90	Updated to work with libprefix.	2006-05-25 22:04:47 +00:00
Michael Brown	29340d7728	Documented the fact that the prefix can prot_call(main) without ... worrying about its stack being destroyed during the Etherboot run.	2006-05-25 22:04:17 +00:00
Michael Brown	0479e9f541	relocate.o is now dragged in by the objects that require it; there is no ... need for a CONFIG_RELOCATE.	2006-05-25 01:34:13 +00:00

Michael Brown	d82f71efd0	Also hide base memory region from E820 map.	2006-05-25 00:10:58 +00:00
Michael Brown	89da833c5d	init_librm() and prot_call() are now real-mode far calls. ... install() now calls relocate(), moves the protected-mode code to the new location, and calls hide_etherboot().	2006-05-25 00:06:45 +00:00
Michael Brown	4d81b48504	Has been obsolete for a while.	2006-05-25 00:04:37 +00:00
Michael Brown	1966945a5d	Update relocate() to work with get_memmap(). ... Change semantics; relocate() now just finds a suitable location; it doesn't actually perform the relocation itself. Code in libprefix does the copy in flat real mode.	2006-05-25 00:04:13 +00:00

Michael Brown	6631f46999	Updated to REAL_CODE().	2006-05-24 12:32:57 +00:00
Michael Brown	53935e9dc6	Set carry flag before calling INT 15,e801 and INT 15,e820. ... Ignore carry flag for INT 15,88; the Ralf Brown interrupt list says that CF is unreliable for this call.	2006-05-24 12:19:16 +00:00
Michael Brown	7a53d07027	Split out REAL_CODE() from REAL_EXEC(), preparatory to removing REAL_EXEC ... completely.	2006-05-24 09:51:04 +00:00
Michael Brown	83d80d9e79	Remove references to obsoleted REAL_CALL from documentation.	2006-05-24 09:16:48 +00:00
Michael Brown	3b525385af	Removed REAL_FRAGMENT and REAL_CALL, and left just REAL_EXEC (which is ... the only one we actually use). This allows REAL_EXEC fragments to contain proper references to constraints (e.g. "%w0"), rather than having to force the use of specific registers. Note that the "num_constraints" parameter is now completely obsolete, and that we can probably reduce the syntax to something like __asm__ __volatile__ ( REAL_CODE ( "asm statements" ) : output constraints : input constraints : clobber ); which would look much more natural, and avoid the need to always specify a clobber list. Add userptr_t to libkir.h, to allow it to at least compile.	2006-05-24 09:14:44 +00:00
Michael Brown	77a65075a6	Replaced memsizes.c with smaller memmap.c, taking advantage of __data16, ... and creating a memory map that's easier to work with than the E820 map.	2006-05-24 01:37:46 +00:00
Michael Brown	5e80847827	Code to install the new E820 mangler (which doesn't require copying ... down to base memory, since it is now in the base-memory-resident .text16 section).	2006-05-23 23:47:05 +00:00
Michael Brown	897313007b	Add __{text,data}16_array, since there's no way I can see to make the ... usual __{text,data}16 trick work with arrays. gcc seems to accept the __asm__ ( asmlabel ) only after the [] of the array declaration, not before.	2006-05-23 23:42:45 +00:00
Michael Brown	5ec2b2c251	Cope with regions bigger than 4GB. ... We now split e820 regions around ourselves, rather than just truncating the e820 region. This avoids the worst-case scenario of losing all memory over 4GB. It's more important to get the memory map right now that we're expecting to still be loaded when the OS starts in several situations (e.g. Linux with UNDI driver, any OS with iSCSI/AoE boot, etc.).	2006-05-23 23:33:37 +00:00
Dan Lynch	bef8874842	- implemented printw (formatted string output, a la printf) ... - implemented hline/vline (part of wborder family) - screen cursor now relocates at same time as window cursor when restoring after a non-wrapping function	2006-05-22 17:03:41 +00:00
Michael Brown	84a493b88d	Allow vcprintf() to be called by external code such as the curses library. ... Also trim another eight bytes from vsprintf.o. :)	2006-05-22 15:41:01 +00:00
Dan Lynch	f778500739	- fixes to _wputch to get positioning and wrap working properly ... - fixes to wborder (same) - addition of a few minor functions	2006-05-22 13:10:19 +00:00

Michael Brown	9dfb9d84b4	Made the LBA48 example clearer.	2006-05-21 16:02:38 +00:00
Michael Brown	80958ff69c	Added (untested) support for ATA devices. This code should be generic ... enough to support both real IDE chipsets and AoE.	2006-05-21 16:01:23 +00:00
Michael Brown	ca2519cea3	Refactored to reduce code size; now down from 1304 to 1105 bytes. ... Tidied up debug messages; the log now contains one line per INT 13 operation, looking like INT 13,08 (80): Get drive parameters INT 13,02 (80): Read: C/H/S 0/47/14 = LBA 0xb9e <-> 1084:0000 (count 106)	2006-05-20 15:33:32 +00:00
Michael Brown	af4aacb978	Added missing @file block	2006-05-20 13:25:07 +00:00
Michael Brown	4d0a0f822d	Use insb/outsb; it's marginally faster.	2006-05-20 12:28:44 +00:00
Michael Brown	402ba15c64	READ CAPACITY (16) turns out to be an optional command (even though ... READ(16) is mandatory); we must use READ CAPACITY (10) first and then use READ CAPACITY (16) if the READ CAPACITY (10) returns "out of range".	2006-05-19 18:54:38 +00:00
Michael Brown	444b885a7d	Add EOVERFLOW==ERANGE	2006-05-19 18:53:12 +00:00
Michael Brown	b9cbae58fa	Expert advice tells me that we *do* have to explicitly state the ... options even when we want to use the defaults.	2006-05-19 17:50:49 +00:00
Dan Lynch	acf572905c	- made some of the bit shifting attribute access simpler (in my mind) ... - added extern declarations for global vars - removed comments from static inlines (too time consuming to do them all, considering all so far have been due to the ridiculous amount of redundancy within the API spec) - removed a few more extern func decls for funcs that cannot be implemented at this time	2006-05-19 16:22:10 +00:00
Dan Lynch	d166dc57ab	- made _wputch wrap lines as well as cols (wraps back to line 0, as we have not way to scroll...) ... - implemented color_content, wborder, wblrtobot, wclrtoeol, wcolor_set and several small functions - added rest of expected global variables	2006-05-19 16:18:08 +00:00
Michael Brown	d48d0fb1bb	Add the concept of a "user pointer" (similar to the void __user * in ... the kernel), which encapsulates the information needed to refer to an external buffer. Under normal operation, this can just be a void * equivalent, but under -DKEEP_IT_REAL it would be a segoff_t equivalent. Use this concept to avoid the need for bounce buffers in int13.c, which reduces memory usage and opens up the possibility of using multi-sector reads. Extend the block-device API and the SCSI block device implementation to support multi-sector reads. Update iscsi.c to use user buffers. Move the obsolete portions of realmode.h to old_realmode.h. MS-DOS now boots an order of magnitude faster over iSCSI (~10 seconds from power-up to C:> prompt in bochs).	2006-05-19 15:06:51 +00:00
Michael Brown	0ab92faedb	Use typeof(sizeof(...)) to define a size_t. This stops gcc complaining ... about format errors for %zX arguments.	2006-05-19 14:51:59 +00:00

Michael Brown	a280587cde	iSCSI writes seem to be working (at least, the ethereal trace shows no ... errors; still need to verify data integrity). SCSI response PDUs are handled: status and sense data (if available) are returned via the scsi_command structure. Updated iSCSI session parameter usage.	2006-05-19 00:20:08 +00:00

Michael Brown	61d7b8a5ef	Added missing drivers/scsi	2006-05-17 17:31:18 +00:00
Michael Brown	a4143e8c87	Split debug functions out into core/debug.c, so that they can be ... automatically linked in on demand. Corrected warnings in misc.c. strtoul() really should be unsigned long strtoul ( const char *p, const char **endp, int base ) but such is not the ANSI standard.	2006-05-17 17:16:24 +00:00
Michael Brown	6b6096d28b	Strip down i386 PCI configuration space I/O to the bare minimum. A ... typical build will now include 880 bytes of PCI support code, compared to 2327 bytes in Etherboot 5.4. (There is a slight cost of around 5 extra bytes per access to a non-constant config space address; this should be an overall win. Driver-specific accesses will usually be to constant addresses, for which there is no additional cost.)	2006-05-17 01:12:11 +00:00
Michael Brown	15ee09ed10	Restructured PCI subsystem to fit the new device model. ... Generic PCI code now handles 64-bit BARs correctly when setting "membase"; drivers should need to call pci_bar_start() only if they want to use BARs other than the first memory or I/O BAR. Split rarely-used PCI functions out into pciextra.c. Core PCI code is now 662 bytes (down from 1308 bytes in Etherboot 5.4). 284 bytes of this saving comes from the pci/pciextra split. Cosmetic changes to lots of drivers (e.g. vendor_id->vendor in order to match the names used in Linux).	2006-05-16 15:12:06 +00:00
Michael Brown	fcdab6299c	Missed a reference to heap.h.	2006-05-16 15:01:26 +00:00
Michael Brown	0afa9db2de	Tear out old heap code, replace with code that simply allocates memory ... for use by malloc(). This breaks the image-loading code (which previously used the heap to allocate the buffer for downloading the image), but that's not a major concern since I'm going to tear out all the image formats within the next couple of days anyway. Byebye, NBI! :)	2006-05-16 15:00:36 +00:00

Michael Brown	25f5d114a0	Updated documentation. ... Shaved around 100 bytes off vsprintf.o. It's now 50 bytes smaller than the old implementation and provides much more conformant semantics, including the ability to return the number of characters that would have been printed to the string had the buffer been big enough. (iSCSI needs this functionality).	2006-05-14 03:31:20 +00:00
Michael Brown	2421723a15	Rewrote printf and friends to better support standard C semantics.	2006-05-14 02:51:55 +00:00
Michael Brown	f99e7a375e	At least cope with "%llx" by reading the correct-sized va_arg from the ... stack, even if we don't yet print it out. At some point, vsprintf() needs to be fixed up so that it can correctly cope with limited-sized buffers (i.e. vsnprintf), long longs, and standard format specifiers (e.g. "%04x"). We should also remove the special types (MAC addresses and IP addresses). This would then enable us to use gcc's ability to type-check printf format strings.	2006-05-13 11:50:52 +00:00

Michael Brown	fdb983d473	Preserve the whole of %esp across prot_call(). We have to split this ... between the low half stored in the static variable rm_sp, and the high half stored on the prot_call() stack, because: Just using the stack would screw up when a prot_call()ed routine executes a real_call(); it would have no way to find the current top of the RM stack. Extending rm_sp to rm_esp would not be safe, because the guarantee that rm_sp must return to the correct value by the time an external real-mode call returns applies only to %sp, not to %esp.	2006-05-06 19:44:23 +00:00
