2008-09-05atmel_lcdfb: fix oops in rmmod when framebuffer fails to registerStanislaw Gruszka
If framebuffer registration failed in platform driver ->probe() callback, dev_get_drvdata() points to freed memory region, but ->remove() function try to use it and the following oops occurs: Unable to handle kernel NULL pointer dereference at virtual address 00000228 pgd = c3a20000 [00000228] *pgd=23a2b031, *pte=00000000, *ppte=00000000 Internal error: Oops: 17 [#1] Modules linked in: atmel_lcdfb(-) cfbcopyarea cfbimgblt cfbfillrect [last unloaded: atmel_lcdfb] CPU: 0 Not tainted (2.6.27-rc2 #116) PC is at atmel_lcdfb_remove+0x14/0xf8 [atmel_lcdfb] LR is at platform_drv_remove+0x20/0x24 pc : [<bf006bc4>] lr : [<c0157d28>] psr: a0000013 sp : c3a45e84 ip : c3a45ea0 fp : c3a45e9c r10: 00000002 r9 : c3a44000 r8 : c0026c04 r7 : 00000880 r6 : c02bb228 r5 : 00000000 r4 : c02bb230 r3 : bf007e3c r2 : c02bb230 r1 : 00000004 r0 : c02bb228 Flags: NzCv IRQs on FIQs on Mode SVC_32 ISA ARM Segment user Control: 0005317f Table: 23a20000 DAC: 00000015 Process rmmod (pid: 6799, stack limit = 0xc3a44260) Stack: (0xc3a45e84 to 0xc3a46000) 5e80: c02bb230 bf007e3c bf007e3c c3a45eac c3a45ea0 c0157d28 bf006bc0 5ea0: c3a45ec4 c3a45eb0 c0156d20 c0157d18 c02bb230 c02bb2d8 c3a45ee0 c3a45ec8 5ec0: c0156da8 c0156cb8 bf007e3c bf007ee0 c02c8e14 c3a45efc c3a45ee4 c0156018 5ee0: c0156d50 bf007e3c bf007ee0 00000000 c3a45f18 c3a45f00 c0157220 c0155f9c 5f00: 00000000 bf007ee0 bf008000 c3a45f28 c3a45f1c c0157e34 c01571ec c3a45f38 5f20: c3a45f2c bf006ba8 c0157e30 c3a45fa4 c3a45f3c c005772c bf006ba4 656d7461 5f40: 636c5f6c 00626664 c004c988 c3a45f80 c3a45f5c 00000000 c3a45fb0 00000000 5f60: ffffffff becaccd8 00000880 00000000 000a5e80 00000001 bf007ee0 00000880 5f80: c3a45f84 00000000 becaccd4 00000002 000003df 00000081 00000000 c3a45fa8 5fa0: c0026a60 c0057584 00000002 000003df 00900081 000a5e80 00000880 00000000 5fc0: becaccd4 00000002 000003df 00000000 000a5e80 00000001 00000002 0000005f 5fe0: 4004f5ec becacbe8 0001a158 4004f5fc 20000010 00900081 f9ffbadf 7bbfb2bb Backtrace: [<bf006bb0>] (atmel_lcdfb_remove+0x0/0xf8 [atmel_lcdfb]) from [<c0157d28>] (platform_drv_remove+0x20/0x24) r6:bf007e3c r5:bf007e3c r4:c02bb230 [<c0157d08>] (platform_drv_remove+0x0/0x24) from [<c0156d20>] (__device_release_driver+0x78/0x98) [<c0156ca8>] (__device_release_driver+0x0/0x98) from [<c0156da8>] (driver_detach+0x68/0x90) r5:c02bb2d8 r4:c02bb230 [<c0156d40>] (driver_detach+0x0/0x90) from [<c0156018>] (bus_remove_driver+0x8c/0xb4) r6:c02c8e14 r5:bf007ee0 r4:bf007e3c [<c0155f8c>] (bus_remove_driver+0x0/0xb4) from [<c0157220>] (driver_unregister+0x44/0x48) r6:00000000 r5:bf007ee0 r4:bf007e3c [<c01571dc>] (driver_unregister+0x0/0x48) from [<c0157e34>] (platform_driver_unregister+0x14/0x18) r6:bf008000 r5:bf007ee0 r4:00000000 [<c0157e20>] (platform_driver_unregister+0x0/0x18) from [<bf006ba8>] (atmel_lcdfb_exit+0x14/0x1c [atmel_lcdfb]) [<bf006b94>] (atmel_lcdfb_exit+0x0/0x1c [atmel_lcdfb]) from [<c005772c>] (sys_delete_module+0x1b8/0x22c) [<c0057574>] (sys_delete_module+0x0/0x22c) from [<c0026a60>] (ret_fast_syscall+0x0/0x2c) r7:00000081 r6:000003df r5:00000002 r4:becaccd4 Code: e92dd870 e24cb004 e59050c4 e1a06000 (e5954228) ---[ end trace 85476b184d9e68d8 ]--- This patch fixes the oops.

This is unnecessary since well encoded LCD_* flags will not generate incorrect combinition of lccr* bits. Skip the check if "lcd_conn" is specified.

2008-08-12radeonfb: fix accel engine hangsDavid Miller
Some chips appear to have the 2D engine hang during screen redraw, typically in a sequence of copyarea operations. This appear to be solved by adding a flush of the engine destination pixel cache and waiting for the engine to be idle before issuing the accel operation. The performance impact seems to be fairly small. Here is a trace on an RV370 (PCI device ID 0x5b64), it records the RBBM_STATUS register, then the source x/y, destination x/y, and width/height used for the copy: ---------------------------------------- radeonfb_prim_copyarea: STATUS[00000140] src[210:70] dst[210:60] wh[a0:10] radeonfb_prim_copyarea: STATUS[00000140] src[2b8:70] dst[2b8:60] wh[88:10] radeonfb_prim_copyarea: STATUS[00000140] src[348:70] dst[348:60] wh[40:10] radeonfb_prim_copyarea: STATUS[80020140] src[390:70] dst[390:60] wh[88:10] radeonfb_prim_copyarea: STATUS[8002613f] src[40:80] dst[40:70] wh[28:10] radeonfb_prim_copyarea: STATUS[80026139] src[a8:80] dst[a8:70] wh[38:10] radeonfb_prim_copyarea: STATUS[80026133] src[e8:80] dst[e8:70] wh[80:10] radeonfb_prim_copyarea: STATUS[8002612d] src[170:80] dst[170:70] wh[30:10] radeonfb_prim_copyarea: STATUS[80026127] src[1a8:80] dst[1a8:70] wh[8:10] radeonfb_prim_copyarea: STATUS[80026121] src[1b8:80] dst[1b8:70] wh[88:10] radeonfb_prim_copyarea: STATUS[8002611b] src[248:80] dst[248:70] wh[68:10] ---------------------------------------- When things are going fine the copies complete before the next ROP is even issued, but all of a sudden the 2D unit becomes active (bit 17 in RBBM_STATUS) and the FIFO retry (bit 13) and FIFO pipeline busy (bit 14) are set as well. The FIFO begins to backup until it becomes full. What happens next is the radeon_fifo_wait() times out, and we access the chip illegally leading to a bus error which usually wedges the box. None of this makes it to the console screen, of course :-) radeon_fifo_wait() should be modified to reset the accelerator when this timeout happens instead of programming the chip anyways. ---------------------------------------- radeonfb: FIFO Timeout !

This will only happen if you 1) VC switch or 2) run "consolechars" or 3) unblank the screen. This seems to happen because until a redraw_screen() the screen scrolling method used by fbcon is not finalized yet. I've seen this with other fb drivers too. So if all you do is boot straight into X you will never see this bug on the relevant chips. Signed-off-by: David S.

This reverts commit 2d04a4a72d7e1519b4838f24bdd4b5d0f3f426dc, which made it impossible to make the softcursor use the highlight colors. Yes, the fourth bit should be "blinking", but since we cannot reasonably blink in fbcon, highlighting it with a bright background is preferable.

2008-08-05radeon: misc correctionsDavid Miller
I have a new PCI-E radeon RV380 series card (PCI device ID 5b64) that hangs in my sparc64 boxes when the init scripts set the font. The problem goes away if I disable acceleration. I haven't figured out that bug yet, but along the way I found some corrections to make based upon some auditing. 1) The RB2D_DC_FLUSH_ALL value used by the kernel fb driver and the XORG video driver differ. I've made the kernel match what XORG is using. 2) In radeonfb_engine_reset() we have top-level code structure that roughly looks like: if (family is 300, 350, or V350) do this; else do that; ... if (family is NOT 300, OR family is NOT 350, OR family is NOT V350) do another thing; this last conditional makes no sense, is always true, and obviously was likely meant to be "family is NOT 300, 350, or V350". So I've made the code match the intent. Signed-off-by: David S.
