2014-12-30libpayload: video: Check for 'console' pointer before dereferencing itJulius Werner
Seems that the 'if (cursor_enabled)' check in video_console_fixup_cursor() that was removed in chromium.org 1f880bca0 really meant to check for 'if (console)'. Looks like the whole video console driver is built extra robust to not fail no matter how screwed up the console is, so let's add this missing check here as well. Also fixed up a few other missing 'if (!console)' checks while I'm at it. However, what payloads should really be doing is check the return value of video_(console_)init() and not call the other video functions if that failed. This also adapts video_console_init() to correctly pass through the return value for that purpose (something that seems to have been overlooked in the dd9e4e58 refactoring). BUG=chrome-os-partner:28494 TEST=None. I don't know what Dave did to trigger this in the first place, but it's pretty straight-forward.

2014-12-30libpayload: video: Make cursor fixup independent of visibilityJulius Werner
The video console runs a video_console_fixup_cursor() function after every printed character to make sure the cursor is still in the output window and avoid overflows. For some crazy reason, this function does not run when cursor_enabled is false... however, that variable is only about cursor *visibility*, and it's imperative that we still do proper bounds checking for our output even if the cursor itself doesn't get displayed (otherwise we can end up overwriting malloc cookies that cause a panic on the next free() and other fun things like that). In fact, there seems to be no reason at all to even keep track of the cursor visibility state in the generic video console framework (the specific backends already do it, too), so let's remove that code entirely. Also set the default cursor visibilty in the corebootfb backend to 0 since that's consistent with what the other backends do. BUG=None TEST=Turn on video console on Big, generate enough output to make it scroll, make sure it does not crash.

2014-12-22libpayload: console: Allow output drivers to print whole strings at onceJulius Werner
The console output driver framework in libpayload is currently built on the putchar primitive, meaning that every driver's function gets called one character at a time. This becomes an issue when we add drivers that could output multiple characters at a time, but have a high constant overhead per invocation (such as the planned GDB stub, which needs to wrap a special frame around output strings and wait for an acknowledgement from the server). This patch adds a new 'write' function pointer to the console_output_driver structure as an alternative to 'putchar'. Output drivers need to provide at least one of the two ('write' is preferred if available). The CBMEM console driver is ported as a proof of concept (since it's our most performace-critical driver and should in theory benefit the most from less function pointer invocations, although it's probably still negligible compared to the big sprawling mess that is printf()). Even with this fix, the problem remains that printf() was written with the putchar primitive in mind. Even though normal text already contains an optimization to allow multiple characters at a time, almost all formatting directives cause their output (including things like padding whitespace) to be putchar()ed one character at a time. Therefore, this patch reworks parts of the output code (especially number printing) to all but remove that inefficiency (directives still invoke an extra write() call, but at least not one per character). Since I'm touching printf() core code anyway, I also tried to salvage what I could from that weird, broken "return negative on error" code path (not that any of our current output drivers can trigger it anyway). A final consequence of this patch is that the responsibility to prepend line feeds with carriage returns is moved into the output driver implementations. Doing this only makes sense for drivers with explicit cursor position control (i.e. serial or video), and things like the CBMEM console that appears like a normal file to the system really have no business containing carriage returns (we don't want people to accidentally associate us with Windows, now, do we?). BUG=chrome-os-partner:18390 TEST=Made sure video and CBMEM console still look good, tried printf() with as many weird edge-case strings as I could find and compared serial output as well as sprintf() return value.

2014-08-05libpayload: Change CONFIG_* to CONFIG_LP_* in the kconfig.Gabe Black
When libpayload header files are included in the payload itself, it's possible that the payloads config settings will conflict with the ones in libpayload. It's also possible for the libpayload config settings to conflict with the payloads. To avoid that, the libpayload config settings have _LP_ (for libpayload) added to them. The symbols themselves as defined in the Config.in files are still the same, but the prefix added to them is now CONFIG_LP_ instead of just CONFIG_.

2012-11-15libpayload: Always use virtual pointers in struct sysinfo_tNico Huber
We had mixed virtual and physical pointers in struct sysinfo_t. Some being virtual by accident which led to problems when we tried to reinitialize lib_sysinfo after relocating FILO (to get intentionally virtual pointers valid again). I guess this didn't cause much trouble before, as lib_get_sysinfo() was always called with physical addresses being equal to their virtual counterparts. For FILO, two possibilities seem practical: Either, have all pointers in struct sysinfo_t physical, so relocation doesn't hurt. Or, have all pointers virtual and call lib_get_sysinfo() again after relocation. This patch goes the latter way, changing the following pointers for situations where virtual pointers differ from physical: .extra_version .build .compile_time .compile_by .compile_host .compile_domain .compiler .linker .assembler .cb_version .vdat_addr .tstamp_table .cbmem_cons .mrc_cache We could also just correct the accidentally virtual pointers. But, IMO, this would lower the risk of future confusion. Note 1: Looks like .version gets never set. Note 2: .option_table and .framebuffer were virtual pointers but treated like physical ones. Even in FILO, this led to no problems as they were set before relocation.
