xrdp의 장점 (vino/vnc 대비)

빠르다

- xrdp에 vino를 붙이면 vnc로 로컬에서 하는 수준?


견고하다(?)
- 딱히 vnc 처럼 깨지는건 못 본 듯


ctrl-c,v가 된다

- vnc는 되다 안되다.. xming 쓰면 절대 안됨


물론 업로드 속도가 된다는 가정하겠지만

xrdp 설정해두고 보니 만세! 임


vino를 통해서 xrdp를 쓰면 로컬에서 하는거니까

chrome 등에서도 openGL 가속받을 수 있고 여러모로 유리함



---

음.. mplayer나 gstramer를 통해서 오디오는 전송이 안되네.. 설정이 누락된게 있나...

아니면.. session으로 한게 아니라 그런가? vino 니까?


lxde 세션이던 gnome vino던 둘다 안되네...

xrdp를 위해 pulseaudio로 뻘짓을 해야하는 건가?

데드풀 (2016)

좀.. 기대 이하?

깨알 같은 셀프 디스가 일품이지만

조금 오버 스런 19금 연출들이 조금 눈에 거슬리고


저예산이라 그런지

일단 스토리도 너무 짧고 빈약하다는게 단점

65/100 점 정도 주면 되려나?

.text .data .code .bss ...

어셈부터 다시 공부좀 해봐야 하나... ㅠㅠ


.text는 코드 영역

.data는 초기화 된 변수

.bss는 초기화되지 않은 변수


어짜피 실행파일(elf?) 에서는 stack / heap이 존재할 이유가 없으니

세개정도의 섹션만 분석하면 답이 나오려나..


highest address

아침부터 아가씨(?) 전화에 흔들리는 마음

1. olleh 하이브리드 에그

이번에 기계값 공짜로 1년간 20기가 더 준대서 문자로 보내달랬더니

대충 1.6만원 이래서 오.. 지금 1.2만원인데 혹해서

가슴이 산들산들 흔들흔들 했으나


확인해보니 10835원이네? 안가 ㅋㅋㅋ

그런데.. 솔찍히 좀 불편하기도 하고.. 약간은 흔들리는 내 마음 ㅠㅠ



[링크 : http://smartblog.olleh.com/4340]


2. ok 캐쉬백 빔프로젝터

필요없어요. 돈 없어요. 도 안통하네 ㄷㄷㄷ

아무튼.. 하루 천원 꼴 12개월 무이자 할부. HD급! 이래서 찾아봤는데

HD는 맞네 720p ㄷㄷ 그래도 많이 싸지고 많이 성능 올라갔네..


근데 쓸데가 없잖아? 패스~

-x

--all-headers

Display all available header information, including the symbol table and relocation entries. Using -x is equivalent to specifying all of -a -f -h -p -r -t.


-h
--section-headers
--headers
Display summary information from the section headers of the object file.
File segments may be relocated to nonstandard addresses, for example by using the -Ttext, -Tdata, or -Tbss options to ld. However, some object file formats, such as a.out, do not store the starting address of the file segments. In those situations, although ld relocates the sections correctly, using objdump -h to list the file section headers cannot show the correct addresses. Instead, it shows the usual addresses, which are implicit for the target.

cortex-m3 인터럽트 관련 조사

master 인터럽트를 disable 하면 어떻게 작동할까?

우연히 그 타이밍에 발생할 인터럽트가 있었다면.. pending 될까? 아니면 그냥 잊혀지는걸까?



SW-DRL-UG-6288.pdf


13.2.2.3 IntMasterDisable

Disables the processor interrupt.

Prototype:

tBoolean

IntMasterDisable(void)

Description:

Prevents the processor from receiving interrupts. This does not affect the set of interrupts

enabled in the interrupt controller; it just gates the single interrupt from the controller to the

processor.

Note:

Previously, this function had no return value. As such, it was possible to include interrupt.h

and call this function without having included hw_types.h. Now that the return is a

tBoolean, a compiler error will occur in this case. The solution is to include hw_types.h

before including interrupt.h.

Returns:

Returns true if interrupts were already disabled when the function was called or false if they

were initially enabled.


13.2.2.4 IntMasterEnable

Enables the processor interrupt.

Prototype:

tBoolean

IntMasterEnable(void)

Description:

Allows the processor to respond to interrupts. This does not affect the set of interrupts enabled

in the interrupt controller; it just gates the single interrupt from the controller to the processor.

Note:

Previously, this function had no return value. As such, it was possible to include interrupt.h

and call this function without having included hw_types.h. Now that the return is a

tBoolean, a compiler error will occur in this case. The solution is to include hw_types.h

before including interrupt.h.

Returns:

Returns true if interrupts were disabled when the function was called or false if they were

initially enabled.


13.2.2.5 IntPendClear

Unpends an interrupt.

Prototype:

void

IntPendClear(unsigned long ulInterrupt)

Parameters:

ulInterrupt specifies the interrupt to be unpended.

Description:

The specified interrupt is unpended in the interrupt controller. This will cause any previously

generated interrupts that have not been handled yet (due to higher priority interrupts or the

interrupt no having been enabled yet) to be discarded.

Returns:

None.


13.2.2.6 IntPendSet

Pends an interrupt.

Prototype:

void

IntPendSet(unsigned long ulInterrupt)

Parameters:

ulInterrupt specifies the interrupt to be pended.

Description:

The specified interrupt is pended in the interrupt controller. This will cause the interrupt con

troller to execute the corresponding interrupt handler at the next available time, based on the

current interrupt state priorities. For example, if called by a higher priority interrupt handler,

the specified interrupt handler will not be called until after the current interrupt handler has

completed execution. The interrupt must have been enabled for it to be called.

Returns:

None.

        // Disable the MemManage interrupt.

        //

        HWREG(NVIC_SYS_HND_CTRL) &= ~(NVIC_SYS_HND_CTRL_MEM);

    }

    else if(ulInterrupt == FAULT_BUS)

    {

        //

        // Disable the bus fault interrupt.

        //

        HWREG(NVIC_SYS_HND_CTRL) &= ~(NVIC_SYS_HND_CTRL_BUS);

    }

    else if(ulInterrupt == FAULT_USAGE)

    {

        //

        // Disable the usage fault interrupt.

        //

        HWREG(NVIC_SYS_HND_CTRL) &= ~(NVIC_SYS_HND_CTRL_USAGE);

    }

    else if(ulInterrupt == FAULT_SYSTICK)

    {

        //

        // Disable the System Tick interrupt.

        //

        HWREG(NVIC_ST_CTRL) &= ~(NVIC_ST_CTRL_INTEN);

    }

    else if((ulInterrupt >= 16) && (ulInterrupt <= 47))

    {

        //

        // Disable the general interrupt.

        //

        HWREG(NVIC_DIS0) = 1 << (ulInterrupt - 16);

    }

    else if(ulInterrupt >= 48)

    {

        //

        // Disable the general interrupt.

        //

        HWREG(NVIC_DIS1) = 1 << (ulInterrupt - 48);

    }

}


cpsid / cpsie 어셈블리 인스트럭션을 통해서 마스터 인터럽트를 제어한다.



SetEnable() 시에는 EN0를


SetDisable() 시에는 DIS0를 사용한다.


용도를 찾지 못한.. 이 펜딩.. 머지?



[링크 : http://www.ti.com/lit/ds/spms037g/spms037g.pdf]



음.. disabled interrupt를 펜딩으로 상태를 설정한다?

즉, enable/disable/pending 세가지 상태 중 하나만 가능한건가?


Writing 1 to the ISPR bit corresponding to:

an interrupt that is pending has no effect

a disabled interrupt sets the state of that interrupt to pending.

svn merge... 두근두근

겁내면서 해봤는데 막상 해보니 별거 없...네?


일단 꼬부기로 시도.

귀찮(?)으니 위에 기본값으로 도전

현재는 머지 되어야 할 head에서 merge를 누름 (branch에서 수정한 내용을 head로 병합)


일단 from 이니까.. branch의 경로를 입력해주고 log를 보고 합칠 범위를 고르면 된다.

한번 밖에 수정안해서.. 그냥 마지막 녀석 하나만 병합


귀찮으니 기본값...


겁나니까 Test merge도 해보고


문제 없으니 Merge를 과감하게 클릭!


그러고 나서 확인해보니..

working copy가 바뀌었네?


merge를 commit 하기 전인데


commit 하니 그냥 하나 추가..

닫히는(?) 선으로 연결될줄 알았더니 시무룩..


음.. 잘못한건 아니겠지? ㅠㅠ

auto merge라는 개념으로는 머.. 서버에 바로 적용되거나 하는건 아닐려나..
